title: Brand guidelines
description: Documentation and examples for Bootstrap's logo and brand usage guidelines.
group: about
toc: true
---
Have a need for Bootstrap's brand resources? Great! We have only a few guidelines we follow, and in turn ask you to follow as well. These guidelines were inspired by MailChimp's [Brand Assets](https://mailchimp.com/about/brand-assets/).
## Mark and logo
Use either the Bootstrap mark (a capital **B**) or the standard logo (just **Bootstrap**). It should always appear in San Francisco Display Semibold. **Do not use the Twitter bird** in association with Bootstrap.
<div class="bd-brand-logos">
<div class="bd-brand-item">
<img class="svg" src="{{ site.baseurl }}/assets/brand/bootstrap-solid.svg" alt="Bootstrap" width="144" height="144">
</div>
<div class="bd-brand-item inverse">
<img class="svg" src="{{ site.baseurl }}/assets/brand/bootstrap-outline.svg" alt="Bootstrap" width="144" height="144">
</div>
</div>
<div class="bd-brand-logos">
<div class="bd-brand-item">
<span class="h1">Bootstrap</span>
</div>
<div class="bd-brand-item inverse">
<span class="h1">Bootstrap</span>
</div>
</div>
## Download mark
Download the Bootstrap mark in one of three styles, each available as an SVG file. Right click, Save as.
<div class="bd-brand-logos">
<div class="bd-brand-item">
<img class="svg" src="{{ site.baseurl }}/assets/brand/bootstrap-solid.svg" alt="Bootstrap" width="144" height="144">
</div>
<div class="bd-brand-item inverse">
<img class="svg" src="{{ site.baseurl }}/assets/brand/bootstrap-outline.svg" alt="Bootstrap" width="144" height="144">
</div>
<div class="bd-brand-item inverse">
<img class="svg" src="{{ site.baseurl }}/assets/brand/bootstrap-punchout.svg" alt="Bootstrap" width="144" height="144">
</div>
</div>
## Name
The project and framework should always be referred to as **Bootstrap**. No Twitter before it, no capital _s_, and no abbreviations except for one, a capital **B**.
<div class="bd-brand-logos">
<div class="bd-brand-item">
<span class="h3">Bootstrap</span>
<strong class="text-success">Right</strong>
</div>
<div class="bd-brand-item">
<span class="h3 text-muted">BootStrap</span>
<strong class="text-warning">Wrong</strong>
</div>
<div class="bd-brand-item">
<span class="h3 text-muted">Twitter Bootstrap</span>
<strong class="text-warning">Wrong</strong>
</div>
</div>
## Colors
Our docs and branding use a handful of primary colors to differentiate what *is* Bootstrap from what *is in* Bootstrap. In other words, if it's purple, it's representative of Bootstrap.
<div class="bd-brand">
<div class="color-swatches">
<div class="color-swatch bd-purple"></div>
<div class="color-swatch bd-purple-light"></div>
<div class="color-swatch bd-purple-lighter"></div>
<div class="color-swatch bd-gray"></div>
</div>
</div>

## Team
Bootstrap is maintained by a [small team of developers](https://github.com/orgs/twbs/people) on GitHub. We're actively looking to grow this team and would love to hear from you if you're excited about CSS at scale, writing and maintaining vanilla JavaScript plugins, and improving build tooling processes for frontend code.
## History
Originally created by a designer and a developer at Twitter, Bootstrap has become one of the most popular front-end frameworks and open source projects in the world.
Bootstrap was created at Twitter in mid-2010 by [@mdo](https://twitter.com/mdo) and [@fat](https://twitter.com/fat). Prior to being an open-sourced framework, Bootstrap was known as _Twitter Blueprint_. A few months into development, Twitter held its [first Hack Week](https://blog.twitter.com/2010/hack-week) and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so today.
Originally [released](https://blog.twitter.com/2011/bootstrap-from-twitter) on [<time datetime="2011-08-19 11:25">Friday, August 19, 2011</time>](https://twitter.com/mdo/statuses/104620039650557952), we've since had over [twenty releases]({{ site.repo }}/releases), including two major rewrites with v2 and v3. With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet. Building on that with Bootstrap 3, we rewrote the library once more to make it responsive by default with a mobile first approach.
With Bootstrap 4, we once again rewrote the project to account for two key architectural changes: a migration to Sass and the move to CSS's flexbox. Our intention is to help in a small way to move the web development community forward by pushing for newer CSS properties, fewer dependencies, and new technologies across more modern browsers.
## Get involved
Get involved with Bootstrap development by [opening an issue]({{ site.repo }}/issues/new) or submitting a pull request. Read our [contributing guidelines]({{ site.repo }}/blob/v{{ site.current_version }}/.github/CONTRIBUTING.md) for information on how we develop.

Bootstrap currently works around several outstanding browser bugs in major browsers to deliver the best cross-browser experience possible. Some bugs, like those listed below, cannot be solved by us.
We publicly list browser bugs that are impacting us here, in the hopes of expediting the process of fixing them. For information on Bootstrap's browser compatibility, [see our browser compatibility docs]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/browsers-devices/#supported-browsers).

# Most wanted features
There are several features specified in Web standards which would allow us to make Bootstrap more robust, elegant, or performant, but aren't yet implemented in certain browsers, thus preventing us from taking advantage of them.
We publicly list these "most wanted" feature requests here, in the hopes of expediting the process of getting them implemented.

title: Alerts
description: Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.
group: components
toc: true
---
## Examples
Alerts are available for any length of text, as well as an optional dismiss button. For proper styling, use one of the eight **required** contextual classes (e.g., `.alert-success`). For inline dismissal, use the [alerts jQuery plugin](#dismissing).
{% example html %}
{% for color in site.data.theme-colors %}
<div class="alert alert-{{ color.name }}" role="alert">
This is a {{ color.name }} alert—check it out!
</div>{% endfor %}
{% endexample %}
{% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %}
{{ callout-include | markdownify }}
### Link color
Use the `.alert-link` utility class to quickly provide matching colored links within any alert.
{% example html %}
{% for color in site.data.theme-colors %}
<div class="alert alert-{{ color.name }}" role="alert">
This is a {{ color.name }} alert with <a href="#" class="alert-link">an example link</a>. Give it a click if you like.
</div>{% endfor %}
{% endexample %}
### Additional content
Alerts can also contain additional HTML elements like headings, paragraphs and dividers.
{% example html %}
<div class="alert alert-success" role="alert">
<h4 class="alert-heading">Well done!</h4>
<p>Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.</p>
<hr>
<p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
</div>
{% endexample %}
### Dismissing
Using the alert JavaScript plugin, it's possible to dismiss any alert inline. Here's how:
- Be sure you've loaded the alert plugin, or the compiled Bootstrap JavaScript.
- If you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util). The compiled version includes this.
- Add a dismiss button and the `.alert-dismissible` class, which adds extra padding to the right of the alert and positions the `.close` button.
- On the dismiss button, add the `data-dismiss="alert"` attribute, which triggers the JavaScript functionality. Be sure to use the `<button>` element with it for proper behavior across all devices.
- To animate alerts when dismissing them, be sure to add the `.fade` and `.show` classes.
You can see this in action with a live demo:
{% example html %}
<div class="alert alert-warning alert-dismissible fade show" role="alert">
<strong>Holy guacamole!</strong> You should check in on some of those fields below.
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
{% endexample %}
## JavaScript behavior
### Triggers
Enable dismissal of an alert via JavaScript:
{% highlight js %}
$('.alert').alert()
{% endhighlight %}
Or with `data` attributes on a button **within the alert**, as demonstrated above:
{% highlight html %}
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
{% endhighlight %}
Note that closing an alert will remove it from the DOM.
### Methods
| Method | Description |
| --- | --- |
| `$().alert()` | Makes an alert listen for click events on descendant elements which have the `data-dismiss="alert"` attribute. (Not necessary when using the data-api's auto-initialization.) |
| `$().alert('close')` | Closes an alert by removing it from the DOM. If the `.fade` and `.show` classes are present on the element, the alert will fade out before it is removed. |
| `$().alert('dispose')` | Destroys an element's alert. |
{% highlight js %}$(".alert").alert('close'){% endhighlight %}
### Events
Bootstrap's alert plugin exposes a few events for hooking into alert functionality.
| Event | Description |
| --- | --- |
| `close.bs.alert` | This event fires immediately when the <code>close</code> instance method is called. |
| `closed.bs.alert` | This event is fired when the alert has been closed (will wait for CSS transitions to complete). |
{% highlight js %}
$('#myAlert').on('closed.bs.alert', function () {
// do something…
})
{% endhighlight %}

title: Badges
description: Documentation and examples for badges, our small count and labeling component.
group: components
toc: true
---
## Example
Badges scale to match the size of the immediate parent element by using relative font sizing and `em` units.
<div class="bd-example">
<div class="h1">Example heading <span class="badge badge-secondary">New</span></div>
<div class="h2">Example heading <span class="badge badge-secondary">New</span></div>
<div class="h3">Example heading <span class="badge badge-secondary">New</span></div>
<div class="h4">Example heading <span class="badge badge-secondary">New</span></div>
<div class="h5">Example heading <span class="badge badge-secondary">New</span></div>
<div class="h6">Example heading <span class="badge badge-secondary">New</span></div>
</div>
{% highlight html %}
<h1>Example heading <span class="badge badge-secondary">New</span></h1>
<h2>Example heading <span class="badge badge-secondary">New</span></h2>
<h3>Example heading <span class="badge badge-secondary">New</span></h3>
<h4>Example heading <span class="badge badge-secondary">New</span></h4>
<h5>Example heading <span class="badge badge-secondary">New</span></h5>
<h6>Example heading <span class="badge badge-secondary">New</span></h6>
{% endhighlight %}
Badges can be used as part of links or buttons to provide a counter.
{% example html %}
<button type="button" class="btn btn-primary">
Notifications <span class="badge badge-light">4</span>
</button>
{% endexample %}
Note that depending on how they are used, badges may be confusing for users of screen readers and similar assistive technologies. While the styling of badges provides a visual cue as to their purpose, these users will simply be presented with the content of the badge. Depending on the specific situation, these badges may seem like random additional words or numbers at the end of a sentence, link, or button.
Unless the context is clear (as with the "Notifications" example, where it is understood that the "4" is the number of notifications), consider including additional context with a visually hidden piece of additional text.
{% example html %}
<button type="button" class="btn btn-primary">
Profile <span class="badge badge-light">9</span>
<span class="sr-only">unread messages</span>
</button>
{% endexample %}
## Contextual variations
Add any of the below mentioned modifier classes to change the appearance of a badge.
{% example html %}
{% for color in site.data.theme-colors %}
<span class="badge badge-{{ color.name }}">{{ color.name | capitalize }}</span>{% endfor %}
{% endexample %}
{% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %}
{{ callout-include | markdownify }}
## Pill badges
Use the `.badge-pill` modifier class to make badges more rounded (with a larger `border-radius` and additional horizontal `padding`). Useful if you miss the badges from v3.
{% example html %}
{% for color in site.data.theme-colors %}
<span class="badge badge-pill badge-{{ color.name }}">{{ color.name | capitalize }}</span>{% endfor %}
{% endexample %}
## Links
Using the contextual `.badge-*` classes on an `<a>` element quickly provide _actionable_ badges with hover and focus states.
{% example html %}
{% for color in site.data.theme-colors %}
<a href="#" class="badge badge-{{ color.name }}">{{ color.name | capitalize }}</a>{% endfor %}
{% endexample %}

title: Breadcrumb
description: Indicate the current page's location within a navigational hierarchy that automatically adds separators via CSS.
group: components
---
## Overview
Separators are automatically added in CSS through [`::before`](https://developer.mozilla.org/en-US/docs/Web/CSS/::before) and [`content`](https://developer.mozilla.org/en-US/docs/Web/CSS/content).
{% example html %}
<nav aria-label="breadcrumb">
<ol class="breadcrumb">
<li class="breadcrumb-item active" aria-current="page">Home</li>
</ol>
</nav>
<nav aria-label="breadcrumb">
<ol class="breadcrumb">
<li class="breadcrumb-item"><a href="#">Home</a></li>
<li class="breadcrumb-item active" aria-current="page">Library</li>
</ol>
</nav>
<nav aria-label="breadcrumb">
<ol class="breadcrumb">
<li class="breadcrumb-item"><a href="#">Home</a></li>
<li class="breadcrumb-item"><a href="#">Library</a></li>
<li class="breadcrumb-item active" aria-current="page">Data</li>
</ol>
</nav>
{% endexample %}
## Accessibility
Since breadcrumbs provide a navigation, it's a good idea to add a meaningful label such as `aria-label="breadcrumb"` to describe the type of navigation provided in the `<nav>` element, as well as applying an `aria-current="page"` to the last item of the set to indicate that it represents the current page.
For more information, see the [WAI-ARIA Authoring Practices for the breadcrumb pattern](https://www.w3.org/TR/wai-aria-practices/#breadcrumb).

layout: docs
title: Button group
description: Group a series of buttons together on a single line with the button group, and super-power them with JavaScript.
group: components
toc: true
---
## Basic example
Wrap a series of buttons with `.btn` in `.btn-group`. Add on optional JavaScript radio and checkbox style behavior with [our buttons plugin]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/buttons/#button-plugin).
{% example html %}
<div class="btn-group" role="group" aria-label="Basic example">
<button type="button" class="btn btn-secondary">Left</button>
<button type="button" class="btn btn-secondary">Middle</button>
<button type="button" class="btn btn-secondary">Right</button>
</div>
{% endexample %}
{% callout warning %}
##### Ensure correct `role` and provide a label
In order for assistive technologies (such as screen readers) to convey that a series of buttons is grouped, an appropriate `role` attribute needs to be provided. For button groups, this would be `role="group"`, while toolbars should have a `role="toolbar"`.
In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct role attribute. In the examples provided here, we use `aria-label`, but alternatives such as `aria-labelledby` can also be used.
{% endcallout %}
## Button toolbar
Combine sets of button groups into button toolbars for more complex components. Use utility classes as needed to space out groups, buttons, and more.
{% example html %}
<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
<div class="btn-group mr-2" role="group" aria-label="First group">
<button type="button" class="btn btn-secondary">1</button>
<button type="button" class="btn btn-secondary">2</button>
<button type="button" class="btn btn-secondary">3</button>
<button type="button" class="btn btn-secondary">4</button>
</div>
<div class="btn-group mr-2" role="group" aria-label="Second group">
<button type="button" class="btn btn-secondary">5</button>
<button type="button" class="btn btn-secondary">6</button>
<button type="button" class="btn btn-secondary">7</button>
</div>
<div class="btn-group" role="group" aria-label="Third group">
<button type="button" class="btn btn-secondary">8</button>
</div>
</div>
{% endexample %}
Feel free to mix input groups with button groups in your toolbars. Similar to the example above, you'll likely need some utilities though to space things properly.
{% example html %}
<div class="btn-toolbar mb-3" role="toolbar" aria-label="Toolbar with button groups">
<div class="btn-group mr-2" role="group" aria-label="First group">
<button type="button" class="btn btn-secondary">1</button>
<button type="button" class="btn btn-secondary">2</button>
<button type="button" class="btn btn-secondary">3</button>
<button type="button" class="btn btn-secondary">4</button>
</div>
<div class="input-group">
<div class="input-group-prepend">
<div class="input-group-text" id="btnGroupAddon">@</div>
</div>
<input type="text" class="form-control" placeholder="Input group example" aria-label="Input group example" aria-describedby="btnGroupAddon">
</div>
</div>
<div class="btn-toolbar justify-content-between" role="toolbar" aria-label="Toolbar with button groups">
<div class="btn-group" role="group" aria-label="First group">
<button type="button" class="btn btn-secondary">1</button>
<button type="button" class="btn btn-secondary">2</button>
<button type="button" class="btn btn-secondary">3</button>
<button type="button" class="btn btn-secondary">4</button>
</div>
<div class="input-group">
<div class="input-group-prepend">
<div class="input-group-text" id="btnGroupAddon2">@</div>
</div>
<input type="text" class="form-control" placeholder="Input group example" aria-label="Input group example" aria-describedby="btnGroupAddon2">
</div>
</div>
{% endexample %}
## Sizing
Instead of applying button sizing classes to every button in a group, just add `.btn-group-*` to each `.btn-group`, including each one when nesting multiple groups.
<div class="bd-example">
<div class="btn-group btn-group-lg" role="group" aria-label="Large button group">
<button type="button" class="btn btn-secondary">Left</button>
<button type="button" class="btn btn-secondary">Middle</button>
<button type="button" class="btn btn-secondary">Right</button>
</div>
<br>
<div class="btn-group" role="group" aria-label="Default button group">
<button type="button" class="btn btn-secondary">Left</button>
<button type="button" class="btn btn-secondary">Middle</button>
<button type="button" class="btn btn-secondary">Right</button>
</div>
<br>
<div class="btn-group btn-group-sm" role="group" aria-label="Small button group">
<button type="button" class="btn btn-secondary">Left</button>
<button type="button" class="btn btn-secondary">Middle</button>
<button type="button" class="btn btn-secondary">Right</button>
</div>
</div>
{% highlight html %}
<div class="btn-group btn-group-lg" role="group" aria-label="...">...</div>
<div class="btn-group" role="group" aria-label="...">...</div>
<div class="btn-group btn-group-sm" role="group" aria-label="...">...</div>
{% endhighlight %}
## Nesting
Place a `.btn-group` within another `.btn-group` when you want dropdown menus mixed with a series of buttons.
{% example html %}
<div class="btn-group" role="group" aria-label="Button group with nested dropdown">
<button type="button" class="btn btn-secondary">1</button>
<button type="button" class="btn btn-secondary">2</button>
<div class="btn-group" role="group">
<button id="btnGroupDrop1" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
</button>
<div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
<a class="dropdown-item" href="#">Dropdown link</a>
<a class="dropdown-item" href="#">Dropdown link</a>
</div>
</div>
</div>
{% endexample %}
## Vertical variation
Make a set of buttons appear vertically stacked rather than horizontally. **Split button dropdowns are not supported here.**
<div class="bd-example">
<div class="btn-group-vertical" role="group" aria-label="Vertical button group">
<button type="button" class="btn btn-secondary">Button</button>
<button type="button" class="btn btn-secondary">Button</button>
<button type="button" class="btn btn-secondary">Button</button>
<button type="button" class="btn btn-secondary">Button</button>
<button type="button" class="btn btn-secondary">Button</button>
<button type="button" class="btn btn-secondary">Button</button>
</div>
</div>
<div class="bd-example">
<div class="btn-group-vertical" role="group" aria-label="Vertical button group">
<button type="button" class="btn btn-secondary">Button</button>
<button type="button" class="btn btn-secondary">Button</button>
<div class="btn-group" role="group">
<button id="btnGroupVerticalDrop1" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
</button>
<div class="dropdown-menu" aria-labelledby="btnGroupVerticalDrop1">
<a class="dropdown-item" href="#">Dropdown link</a>
<a class="dropdown-item" href="#">Dropdown link</a>
</div>
</div>
<button type="button" class="btn btn-secondary">Button</button>
<button type="button" class="btn btn-secondary">Button</button>
<div class="btn-group" role="group">
<button id="btnGroupVerticalDrop2" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

title: Buttons
description: Use Bootstrap's custom button styles for actions in forms, dialogs, and more with support for multiple sizes, states, and more.
group: components
redirect_from: "/docs/4.0/components/"
toc: true
---
## Examples
Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.
{% example html %}
{% for color in site.data.theme-colors %}
<button type="button" class="btn btn-{{ color.name }}">{{ color.name | capitalize }}</button>{% endfor %}
<button type="button" class="btn btn-link">Link</button>
{% endexample %}
{% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %}
{{ callout-include | markdownify }}
## Button tags
The `.btn` classes are designed to be used with the `<button>` element. However, you can also use these classes on `<a>` or `<input>` elements (though some browsers may apply a slightly different rendering).
When using button classes on `<a>` elements that are used to trigger in-page functionality (like collapsing content), rather than linking to new pages or sections within the current page, these links should be given a `role="button"` to appropriately convey their purpose to assistive technologies such as screen readers.
{% example html %}
<a class="btn btn-primary" href="#" role="button">Link</a>
<button class="btn btn-primary" type="submit">Button</button>
<input class="btn btn-primary" type="button" value="Input">
<input class="btn btn-primary" type="submit" value="Submit">
<input class="btn btn-primary" type="reset" value="Reset">
{% endexample %}
## Outline buttons
In need of a button, but not the hefty background colors they bring? Replace the default modifier classes with the `.btn-outline-*` ones to remove all background images and colors on any button.
{% example html %}
{% for color in site.data.theme-colors %}
<button type="button" class="btn btn-outline-{{ color.name }}">{{ color.name | capitalize }}</button>{% endfor %}
{% endexample %}
## Sizes
Fancy larger or smaller buttons? Add `.btn-lg` or `.btn-sm` for additional sizes.
{% example html %}
<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-secondary btn-lg">Large button</button>
{% endexample %}
{% example html %}
<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-secondary btn-sm">Small button</button>
{% endexample %}
Create block level buttons—those that span the full width of a parent—by adding `.btn-block`.
{% example html %}
<button type="button" class="btn btn-primary btn-lg btn-block">Block level button</button>
<button type="button" class="btn btn-secondary btn-lg btn-block">Block level button</button>
{% endexample %}
## Active state
Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. **There's no need to add a class to `<button>`s as they use a pseudo-class**. However, you can still force the same active appearance with `.active` (and include the <code>aria-pressed="true"</code> attribute) should you need to replicate the state programmatically.
{% example html %}
<a href="#" class="btn btn-primary btn-lg active" role="button" aria-pressed="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg active" role="button" aria-pressed="true">Link</a>
{% endexample %}
## Disabled state
Make buttons look inactive by adding the `disabled` boolean attribute to any `<button>` element.
{% example html %}
<button type="button" class="btn btn-lg btn-primary" disabled>Primary button</button>
<button type="button" class="btn btn-secondary btn-lg" disabled>Button</button>
{% endexample %}
Disabled buttons using the `<a>` element behave a bit different:
- `<a>`s don't support the `disabled` attribute, so you must add the `.disabled` class to make it visually appear disabled.
- Some future-friendly styles are included to disable all `pointer-events` on anchor buttons. In browsers which support that property, you won't see the disabled cursor at all.
- Disabled buttons should include the `aria-disabled="true"` attribute to indicate the state of the element to assistive technologies.
{% example html %}
<a href="#" class="btn btn-primary btn-lg disabled" role="button" aria-disabled="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg disabled" role="button" aria-disabled="true">Link</a>
{% endexample %}
{% callout warning %}
##### Link functionality caveat
The `.disabled` class uses `pointer-events: none` to try to disable the link functionality of `<a>`s, but that CSS property is not yet standardized. In addition, even in browsers that do support `pointer-events: none`, keyboard navigation remains unaffected, meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links. So to be safe, add a `tabindex="-1"` attribute on these links (to prevent them from receiving keyboard focus) and use custom JavaScript to disable their functionality.
{% endcallout %}
## Button plugin
Do more with buttons. Control button states or create groups of buttons for more components like toolbars.
### Toggle states
Add `data-toggle="button"` to toggle a button's `active` state. If you're pre-toggling a button, you must manually add the `.active` class **and** `aria-pressed="true"` to the `<button>`.
{% example html %}
<button type="button" class="btn btn-primary" data-toggle="button" aria-pressed="false" autocomplete="off">
Single toggle
</button>
{% endexample %}
### Checkbox and radio buttons
Bootstrap's `.button` styles can be applied to other elements, such as `<label>`s, to provide checkbox or radio style button toggling. Add `data-toggle="buttons"` to a `.btn-group` containing those modified buttons to enable their toggling behavior via JavaScript and add `.btn-group-toggle` to style the `<input>`s within your buttons. **Note that you can create single input-powered buttons or groups of them.**
The checked state for these buttons is **only updated via `click` event** on the button. If you use another method to update the input—e.g., with `<input type="reset">` or by manually applying the input's `checked` property—you'll need to toggle `.active` on the `<label>` manually.
Note that pre-checked buttons require you to manually add the `.active` class to the input's `<label>`.
{% example html %}
<div class="btn-group-toggle" data-toggle="buttons">
<label class="btn btn-secondary active">
<input type="checkbox" checked autocomplete="off"> Checked
</label>
</div>
{% endexample %}
{% example html %}
<div class="btn-group btn-group-toggle" data-toggle="buttons">
<label class="btn btn-secondary active">
<input type="radio" name="options" id="option1" autocomplete="off" checked> Active
</label>
<label class="btn btn-secondary">
<input type="radio" name="options" id="option2" autocomplete="off"> Radio
</label>
<label class="btn btn-secondary">
<input type="radio" name="options" id="option3" autocomplete="off"> Radio
</label>
</div>
{% endexample %}
### Methods
| Method | Description |
| --- | --- |
| `$().button('toggle')` | Toggles push state. Gives the button the appearance that it has been activated. |
| `$().button('dispose')` | Destroys an element's button. |

title: Cards
description: Bootstrap's cards provide a flexible and extensible content container with multiple variants and options.
group: components
toc: true
---
## About
A **card** is a flexible and extensible content container. It includes options for headers and footers, a wide variety of content, contextual background colors, and powerful display options. If you're familiar with Bootstrap 3, cards replace our old panels, wells, and thumbnails. Similar functionality to those components is available as modifier classes for cards.
## Example
Cards are built with as little markup and styles as possible, but still manage to deliver a ton of control and customization. Built with flexbox, they offer easy alignment and mix well with other Bootstrap components. They have no `margin` by default, so use [spacing utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) as needed.
Below is an example of a basic card with mixed content and a fixed width. Cards have no fixed width to start, so they'll naturally fill the full width of its parent element. This is easily customized with our various [sizing options](#sizing).
{% example html %}
<div class="card" style="width: 18rem;">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
{% endexample %}
## Content types
Cards support a wide variety of content, including images, text, list groups, links, and more. Below are examples of what's supported.
### Body
The building block of a card is the `.card-body`. Use it whenever you need a padded section within a card.
{% example html %}
<div class="card">
<div class="card-body">
This is some text within a card body.
</div>
</div>
{% endexample %}
### Titles, text, and links
Card titles are used by adding `.card-title` to a `<h*>` tag. In the same way, links are added and placed next to each other by adding `.card-link` to an `<a>` tag.
Subtitles are used by adding a `.card-subtitle` to a `<h*>` tag. If the `.card-title` and the `.card-subtitle` items are placed in a `.card-body` item, the card title and subtitle are aligned nicely.
{% example html %}
<div class="card" style="width: 18rem;">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<h6 class="card-subtitle mb-2 text-muted">Card subtitle</h6>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
<a href="#" class="card-link">Card link</a>
<a href="#" class="card-link">Another link</a>
</div>
</div>
{% endexample %}
### Images
`.card-img-top` places an image to the top of the card. With `.card-text`, text can be added to the card. Text within `.card-text` can also be styled with the standard HTML tags.
{% example html %}
<div class="card" style="width: 18rem;">
<img class="card-img-top" data-src="holder.js/100px180/?text=Image cap" alt="Card image cap">
<div class="card-body">
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
</div>
</div>
{% endexample %}
### List groups
Create lists of content in a card with a flush list group.
{% example html %}
<div class="card" style="width: 18rem;">
<ul class="list-group list-group-flush">
<li class="list-group-item">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>
<li class="list-group-item">Vestibulum at eros</li>
</ul>
</div>
{% endexample %}
{% example html %}
<div class="card" style="width: 18rem;">
<div class="card-header">
Featured
</div>
<ul class="list-group list-group-flush">
<li class="list-group-item">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>
<li class="list-group-item">Vestibulum at eros</li>
</ul>
</div>
{% endexample %}
### Kitchen sink
Mix and match multiple content types to create the card you need, or throw everything in there. Shown below are image styles, blocks, text styles, and a list group—all wrapped in a fixed-width card.
{% example html %}
<div class="card" style="width: 18rem;">
<img class="card-img-top" data-src="holder.js/100px180/?text=Image cap" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
</div>
<ul class="list-group list-group-flush">
<li class="list-group-item">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>
<li class="list-group-item">Vestibulum at eros</li>
</ul>
<div class="card-body">
<a href="#" class="card-link">Card link</a>
<a href="#" class="card-link">Another link</a>
</div>
</div>
{% endexample %}
### Header and footer
Add an optional header and/or footer within a card.
{% example html %}
<div class="card">
<div class="card-header">
Featured
</div>
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
{% endexample %}
Card headers can be styled by adding `.card-header` to `<h*>` elements.
{% example html %}
<div class="card">
<h5 class="card-header">Featured</h5>
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
{% endexample %}
{% example html %}
<div class="card">
<div class="card-header">
Quote
</div>
<div class="card-body">
<blockquote class="blockquote mb-0">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
<footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>
</div>
</div>
{% endexample %}
{% example html %}
<div class="card text-center">
<div class="card-header">
Featured
</div>
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
<div class="card-footer text-muted">
2 days ago
</div>
</div>
{% endexample %}
## Sizing
Cards assume no specific `width` to start, so they'll be 100% wide unless otherwise stated. You can change this as needed with custom CSS, grid classes, grid Sass mixins, or utilities.
### Using grid markup
Using the grid, wrap cards in columns and rows as needed.
{% example html %}
<div class="row">
<div class="col-sm-6">
<div class="card">
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
</div>
<div class="col-sm-6">
<div class="card">
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
</div>
</div>
{% endexample %}
### Using utilities
Use our handful of [available sizing utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/sizing/) to quickly set a card's width.
{% example html %}
<div class="card w-75">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Button</a>
</div>
</div>
<div class="card w-50">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Button</a>
</div>
</div>
{% endexample %}
### Using custom CSS
Use custom CSS in your stylesheets or as inline styles to set a width.
{% example html %}
<div class="card" style="width: 18rem;">
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
{% endexample %}
## Text alignment
You can quickly change the text alignment of any card—in its entirety or specific parts—with our [text align classes]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/#text-alignment).
{% example html %}
<div class="card" style="width: 18rem;">
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
<div class="card text-center" style="width: 18rem;">
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
<div class="card text-right" style="width: 18rem;">
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
{% endexample %}
## Navigation
Add some navigation to a card's header (or block) with Bootstrap's [nav components]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/navs/).
{% example html %}
<div class="card text-center">
<div class="card-header">
<ul class="nav nav-tabs card-header-tabs">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
</div>
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
{% endexample %}
{% example html %}
<div class="card text-center">
<div class="card-header">
<ul class="nav nav-pills card-header-pills">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
</div>
<div class="card-body">
<h5 class="card-title">Special title treatment</h5>
<p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
{% endexample %}
## Images
Cards include a few options for working with images. Choose from appending "image caps" at either end of a card, overlaying images with card content, or simply embedding the image in a card.
### Image caps
Similar to headers and footers, cards can include top and bottom "image caps"—images at the top or bottom of a card.
{% example html %}
<div class="card mb-3">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
<div class="card">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
<img class="card-img-bottom" data-src="holder.js/100px180/" alt="Card image cap">
</div>
{% endexample %}
### Image overlays
Turn an image into a card background and overlay your card's text. Depending on the image, you may or may not need additional styles or utilities.
{% example html %}
<div class="card bg-dark text-white">
<img class="card-img" data-src="holder.js/100px270/#55595c:#373a3c/text:Card image" alt="Card image">
<div class="card-img-overlay">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<p class="card-text">Last updated 3 mins ago</p>
</div>
</div>
{% endexample %}
## Card styles
Cards include various options for customizing their backgrounds, borders, and color.
### Background and color
Use [text and background utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/colors/) to change the appearance of a card.
{% example html %}
{% for color in site.data.theme-colors %}
<div class="card{% unless color.name == "light" %} text-white{% endunless %} bg-{{ color.name }} mb-3" style="max-width: 18rem;">
<div class="card-header">Header</div>
<div class="card-body">
<h5 class="card-title">{{ color.name | capitalize }} card title</h5>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
</div>
</div>{% endfor %}
{% endexample %}
{% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %}
{{ callout-include | markdownify }}
### Border
Use [border utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/borders/) to change just the `border-color` of a card. Note that you can put `.text-{color}` classes on the parent `.card` or a subset of the card's contents as shown below.
{% example html %}
{% for color in site.data.theme-colors %}
<div class="card border-{{ color.name }} mb-3" style="max-width: 18rem;">
<div class="card-header">Header</div>
<div class="card-body{% unless color.name == "light" %} text-{{ color.name }}{% endunless %}">
<h5 class="card-title">{{ color.name | capitalize }} card title</h5>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
</div>
</div>{% endfor %}
{% endexample %}
### Mixins utilities
You can also change the borders on the card header and footer as needed, and even remove their `background-color` with `.bg-transparent`.
{% example html %}
<div class="card border-success mb-3" style="max-width: 18rem;">
<div class="card-header bg-transparent border-success">Header</div>
<div class="card-body text-success">
<h5 class="card-title">Success card title</h5>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
</div>
<div class="card-footer bg-transparent border-success">Footer</div>
</div>
{% endexample %}
## Card layout
In addition to styling the content within cards, Bootstrap includes a few options for laying out series of cards. For the time being, **these layout options are not yet responsive**.
### Card groups
Use card groups to render cards as a single, attached element with equal width and height columns. Card groups use `display: flex;` to achieve their uniform sizing.
{% example html %}
<div class="card-group">
<div class="card">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
<div class="card">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
<div class="card">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
</div>
{% endexample %}
When using card groups with footers, their content will automatically line up.
{% example html %}
<div class="card-group">
<div class="card">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
</div>
<div class="card-footer">
<small class="text-muted">Last updated 3 mins ago</small>
</div>
</div>
<div class="card">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
</div>
<div class="card-footer">
<small class="text-muted">Last updated 3 mins ago</small>
</div>

### Card decks
Need a set of equal width and height cards that aren't attached to one another? Use card decks.
{% example html %}
<div class="card-deck">
<div class="card">
<img class="card-img-top" data-src="holder.js/100px200/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
<div class="card">
<img class="card-img-top" data-src="holder.js/100px200/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
<div class="card">
<img class="card-img-top" data-src="holder.js/100px200/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
</div>
{% endexample %}
Just like with card groups, card footers in decks will automatically line up.
{% example html %}
<div class="card-deck">
<div class="card">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
</div>
<div class="card-footer">
<small class="text-muted">Last updated 3 mins ago</small>
</div>
</div>
<div class="card">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
</div>
<div class="card-footer">
<small class="text-muted">Last updated 3 mins ago</small>
</div>
</div>
<div class="card">
<img class="card-img-top" data-src="holder.js/100px180/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
</div>
<div class="card-footer">
<small class="text-muted">Last updated 3 mins ago</small>
</div>
</div>
</div>
{% endexample %}
### Card columns
Cards can be organized into [Masonry](https://masonry.desandro.com/)-like columns with just CSS by wrapping them in `.card-columns`. Cards are built with CSS `column` properties instead of flexbox for easier alignment. Cards are ordered from top to bottom and left to right.
**Heads up!** Your mileage with card columns may vary. To prevent cards breaking across columns, we must set them to `display: inline-block` as `column-break-inside: avoid` isn't a bulletproof solution yet.
{% example html %}
<div class="card-columns">
<div class="card">
<img class="card-img-top" data-src="holder.js/100px160/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title that wraps to a new line</h5>
<p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
</div>
</div>
<div class="card p-3">
<blockquote class="blockquote mb-0 card-body">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
<footer class="blockquote-footer">
<small class="text-muted">
Someone famous in <cite title="Source Title">Source Title</cite>
</small>
</footer>
</blockquote>
</div>
<div class="card">
<img class="card-img-top" data-src="holder.js/100px160/" alt="Card image cap">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
<div class="card bg-primary text-white text-center p-3">
<blockquote class="blockquote mb-0">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat.</p>
<footer class="blockquote-footer">
<small>
Someone famous in <cite title="Source Title">Source Title</cite>
</small>
</footer>
</blockquote>
</div>
<div class="card text-center">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
<div class="card">
<img class="card-img" data-src="holder.js/100px260/" alt="Card image">
</div>
<div class="card p-3 text-right">
<blockquote class="blockquote mb-0">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
<footer class="blockquote-footer">
<small class="text-muted">

</div>
<div class="card">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
<p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
</div>
</div>
</div>
{% endexample %}
Card columns can also be extended and customized with some additional code. Shown below is an extension of the `.card-columns` class using the same CSS we use—CSS columns— to generate a set of responsive tiers for changing the number of columns.
{% highlight scss %}
.card-columns {
@include media-breakpoint-only(lg) {
column-count: 4;
}
@include media-breakpoint-only(xl) {
column-count: 5;
}
}
{% endhighlight %}

title: Carousel
description: A slideshow component for cycling through elements—images or slides of text—like a carousel.
group: components
toc: true
---
## How it works
The carousel is a slideshow for cycling through a series of content, built with CSS 3D transforms and a bit of JavaScript. It works with a series of images, text, or custom markup. It also includes support for previous/next controls and indicators.
In browsers where the [Page Visibility API](https://www.w3.org/TR/page-visibility/) is supported, the carousel will avoid sliding when the webpage is not visible to the user (such as when the browser tab is inactive, the browser window is minimized, etc.).
Please be aware that nested carousels are not supported, and carousels are generally not compliant with accessibility standards.
Lastly, if you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util).
## Example
Carousels don't automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. While carousels support previous/next controls and indicators, they're not explicitly required. Add and customize as you see fit.
Be sure to set a unique id on the `.carousel` for optional controls, especially if you're using multiple carousels on a single page.
### Slides only
Here's a carousel with slides only. Note the presence of the `.d-block` and `.img-fluid` on carousel images to prevent browser default image alignment.
{% example html %}
<div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel">
<div class="carousel-inner">
<div class="carousel-item active">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=777&fg=555&text=First slide" alt="First slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=666&fg=444&text=Second slide" alt="Second slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=555&fg=333&text=Third slide" alt="Third slide">
</div>
</div>
</div>
{% endexample %}
### With controls
Adding in the previous and next controls:
{% example html %}
<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
<div class="carousel-inner">
<div class="carousel-item active">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=777&fg=555&text=First slide" alt="First slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=666&fg=444&text=Second slide" alt="Second slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=555&fg=333&text=Third slide" alt="Third slide">
</div>
</div>
<a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
{% endexample %}
### With indicators
You can also add the indicators to the carousel, alongside the controls, too.
{% example html %}
<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
<li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
<li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
</ol>
<div class="carousel-inner">
<div class="carousel-item active">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=777&fg=555&text=First slide" alt="First slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=666&fg=444&text=Second slide" alt="Second slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=555&fg=333&text=Third slide" alt="Third slide">
</div>
</div>
<a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
{% endexample %}
{% callout warning %}
##### Initial active element required
The `.active` class needs to be added to one of the slides. Otherwise, the carousel will not be visible.
{% endcallout %}
### With captions
Add captions to your slides easily with the `.carousel-caption` element within any `.carousel-item`. They can be easily hidden on smaller viewports, as shown below, with optional [display utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/display/). We hide them initially with `.d-none` and bring them back on medium-sized devices with `.d-md-block`.
<div class="bd-example">
<div id="carouselExampleCaptions" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-target="#carouselExampleCaptions" data-slide-to="0" class="active"></li>
<li data-target="#carouselExampleCaptions" data-slide-to="1"></li>
<li data-target="#carouselExampleCaptions" data-slide-to="2"></li>
</ol>
<div class="carousel-inner">
<div class="carousel-item active">
<img class="d-block w-100" data-src="holder.js/800x400?auto=yes&bg=777&fg=555&text=First slide" alt="First slide">
<div class="carousel-caption d-none d-md-block">

</div>
{% highlight html %}
<div class="carousel-item">
<img src="..." alt="...">
<div class="carousel-caption d-none d-md-block">
<h5>...</h5>
<p>...</p>
</div>
</div>
{% endhighlight %}
## Usage
### Via data attributes
Use data attributes to easily control the position of the carousel. `data-slide` accepts the keywords `prev` or `next`, which alters the slide position relative to its current position. Alternatively, use `data-slide-to` to pass a raw slide index to the carousel `data-slide-to="2"`, which shifts the slide position to a particular index beginning with `0`.
The `data-ride="carousel"` attribute is used to mark a carousel as animating starting at page load. **It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.**
### Via JavaScript
Call carousel manually with:
{% highlight js %}
$('.carousel').carousel()
{% endhighlight %}
### Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-interval=""`.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 100px;">Name</th>
<th style="width: 50px;">Type</th>
<th style="width: 50px;">Default</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>interval</td>
<td>number</td>
<td>5000</td>
<td>The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle.</td>
</tr>
<tr>
<td>keyboard</td>
<td>boolean</td>
<td>true</td>
<td>Whether the carousel should react to keyboard events.</td>
</tr>
<tr>
<td>pause</td>
<td>string | boolean</td>
<td>"hover"</td>
<td><p>If set to <code>"hover"</code>, pauses the cycling of the carousel on <code>mouseenter</code> and resumes the cycling of the carousel on <code>mouseleave</code>. If set to <code>false</code>, hovering over the carousel won't pause it.</p>
<p>On touch-enabled devices, when set to <code>"hover"</code>, cycling will pause on <code>touchend</code> (once the user finished interacting with the carousel) for two intervals, before automatically resuming. Note that this is in addition to the above mouse behavior.</p></td>
</tr>
<tr>
<td>ride</td>
<td>string</td>
<td>false</td>
<td>Autoplays the carousel after the user manually cycles the first item. If "carousel", autoplays the carousel on load.</td>
</tr>
<tr>
<td>wrap</td>
<td>boolean</td>
<td>true</td>
<td>Whether the carousel should cycle continuously or have hard stops.</td>
</tr>
</tbody>
</table>
### Methods
{% capture callout-include %}{% include callout-danger-async-methods.md %}{% endcapture %}
{{ callout-include | markdownify }}
#### `.carousel(options)`
Initializes the carousel with an optional options `object` and starts cycling through items.
{% highlight js %}
$('.carousel').carousel({
interval: 2000
})
{% endhighlight %}
#### `.carousel('cycle')`
Cycles through the carousel items from left to right.
#### `.carousel('pause')`
Stops the carousel from cycling through items.
#### `.carousel(number)`
Cycles the carousel to a particular frame (0 based, similar to an array). **Returns to the caller before the target item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
#### `.carousel('prev')`
Cycles to the previous item. **Returns to the caller before the previous item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
#### `.carousel('next')`
Cycles to the next item. **Returns to the caller before the next item has been shown** (i.e. before the `slid.bs.carousel` event occurs).
#### `.carousel('dispose')`
Destroys an element's carousel.
### Events
Bootstrap's carousel class exposes two events for hooking into carousel functionality. Both events have the following additional properties:
- `direction`: The direction in which the carousel is sliding (either `"left"` or `"right"`).
- `relatedTarget`: The DOM element that is being slid into place as the active item.
- `from`: The index of the current item
- `to`: The index of the next item
All carousel events are fired at the carousel itself (i.e. at the `<div class="carousel">`).
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 150px;">Event Type</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>slide.bs.carousel</td>
<td>This event fires immediately when the <code>slide</code> instance method is invoked.</td>
</tr>
<tr>
<td>slid.bs.carousel</td>
<td>This event is fired when the carousel has completed its slide transition.</td>
</tr>
</tbody>
</table>
{% highlight js %}
$('#myCarousel').on('slide.bs.carousel', function () {
// do something…
})
{% endhighlight %}

title: Collapse
description: Toggle the visibility of content across your project with a few classes and our JavaScript plugins.
group: components
toc: true
---
## Example
Click the buttons below to show and hide another element via class changes:
- `.collapse` hides content
- `.collapsing` is applied during transitions
- `.collapse.show` shows content
You can use a link with the `href` attribute, or a button with the `data-target` attribute. In both cases, the `data-toggle="collapse"` is required.
{% example html %}
<p>
<a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">
Link with href
</a>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
Button with data-target
</button>
</p>
<div class="collapse" id="collapseExample">
<div class="card card-body">
Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.
</div>
</div>
{% endexample %}
## Multiple targets
A `<button>` or `<a>` can show and hide multiple elements by referencing them with a JQuery selector in its `href` or `data-target` attribute.
Multiple `<button>` or `<a>` can show and hide an element if they each reference it with their `href` or `data-target` attribute
{% example html %}
<p>
<a class="btn btn-primary" data-toggle="collapse" href="#multiCollapseExample1" role="button" aria-expanded="false" aria-controls="multiCollapseExample1">Toggle first element</a>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#multiCollapseExample2" aria-expanded="false" aria-controls="multiCollapseExample2">Toggle second element</button>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target=".multi-collapse" aria-expanded="false" aria-controls="multiCollapseExample1 multiCollapseExample2">Toggle both elements</button>
</p>
<div class="row">
<div class="col">
<div class="collapse multi-collapse" id="multiCollapseExample1">
<div class="card card-body">

</div>
{% endexample %}
## Accordion example
Using the [card]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/card/) component, you can extend the default collapse behavior to create an accordion.
{% example html %}
<div id="accordion">

</div>
</div>
{% endexample %}
## Accessibility
Be sure to add `aria-expanded` to the control element. This attribute explicitly conveys the current state of the collapsible element tied to the control to screen readers and similar assistive technologies. If the collapsible element is closed by default, the attribute on the control element should have a value of `aria-expanded="false"`. If you've set the collapsible element to be open by default using the `show` class, set `aria-expanded="true"` on the control instead. The plugin will automatically toggle this attribute on the control based on whether or not the collapsible element has been opened or closed (via JavaScript, or because the user triggered another control element also tied to the same collapsbile element). If the control element's HTML element is not a button (e.g., an `<a>` or `<div>`), the attribute `role="button"` should be added to the element.
If your control element is targeting a single collapsible element i.e. the `data-target` attribute is pointing to an `id` selector you should add the `aria-controls` attribute to the control element, containing the `id` of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.
Note that Bootstrap's current implementation does not cover the various keyboard interactions described in the [WAI-ARIA Authoring Practices 1.1 accordion pattern](https://www.w3.org/TR/wai-aria-practices-1.1/#accordion) - you will need to include these yourself with custom JavaScript.
## Usage
The collapse plugin utilizes a few classes to handle the heavy lifting:
- `.collapse` hides the content
- `.collapse.show` shows the content
- `.collapsing` is added when the transition starts, and removed when it finishes
These classes can be found in `_transitions.scss`.
### Via data attributes
Just add `data-toggle="collapse"` and a `data-target` to the element to automatically assign control of one or more collapsible elements. The `data-target` attribute accepts a CSS selector to apply the collapse to. Be sure to add the class `collapse` to the collapsible element. If you'd like it to default open, add the additional class `show`.
To add accordion-like group management to a collapsible area, add the data attribute `data-parent="#selector"`. Refer to the demo to see this in action.
### Via JavaScript
Enable manually with:
{% highlight js %}
$('.collapse').collapse()
{% endhighlight %}
### Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-parent=""`.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 100px;">Name</th>
<th style="width: 50px;">Type</th>
<th style="width: 50px;">Default</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>parent</td>
<td>selector | jQuery object | DOM element </td>
<td>false</td>
<td>If parent is provided, then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this is dependent on the <code>card</code> class). The attribute has to be set on the target collapsible area.</td>
</tr>
<tr>
<td>toggle</td>
<td>boolean</td>
<td>true</td>
<td>Toggles the collapsible element on invocation</td>
</tr>
</tbody>
</table>
### Methods
{% capture callout-include %}{% include callout-danger-async-methods.md %}{% endcapture %}
{{ callout-include | markdownify }}
#### `.collapse(options)`
Activates your content as a collapsible element. Accepts an optional options `object`.
{% highlight js %}
$('#myCollapsible').collapse({
toggle: false
})
{% endhighlight %}
#### `.collapse('toggle')`
Toggles a collapsible element to shown or hidden. **Returns to the caller before the collapsible element has actually been shown or hidden** (i.e. before the `shown.bs.collapse` or `hidden.bs.collapse` event occurs).
#### `.collapse('show')`
Shows a collapsible element. **Returns to the caller before the collapsible element has actually been shown** (i.e. before the `shown.bs.collapse` event occurs).
#### `.collapse('hide')`
Hides a collapsible element. **Returns to the caller before the collapsible element has actually been hidden** (i.e. before the `hidden.bs.collapse` event occurs).
#### `.collapse('dispose')`
Destroys an element's collapse.
### Events
Bootstrap's collapse class exposes a few events for hooking into collapse functionality.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 150px;">Event Type</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>show.bs.collapse</td>
<td>This event fires immediately when the <code>show</code> instance method is called.</td>
</tr>
<tr>
<td>shown.bs.collapse</td>
<td>This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete).</td>
</tr>
<tr>
<td>hide.bs.collapse</td>
<td>This event is fired immediately when the <code>hide</code> method has been called.</td>
</tr>
<tr>
<td>hidden.bs.collapse</td>
<td>This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete).</td>
</tr>
</tbody>
</table>
{% highlight js %}
$('#myCollapsible').on('hidden.bs.collapse', function () {
// do something…
})
{% endhighlight %}

title: Dropdowns
description: Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.
group: components
toc: true
---
## Overview
Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They're made interactive with the included Bootstrap dropdown JavaScript plugin. They're toggled by clicking, not by hovering; this is [an intentional design decision.](http://markdotto.com/2012/02/27/bootstrap-explained-dropdowns/)
Dropdowns are built on a third party library, [Popper.js](https://popper.js.org/), which provides dynamic positioning and viewport detection. Be sure to include [popper.min.js]({{ site.cdn.popper }}) before Bootstrap's JavaScript or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper.js. Popper.js isn't used to position dropdowns in navbars though as dynamic positioning isn't required.
If you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util).
## Accessibility
The [<abbr title="Web Accessibility Initiative">WAI</abbr> <abbr title="Accessible Rich Internet Applications">ARIA</abbr>](https://www.w3.org/TR/wai-aria/) standard defines an actual [`role="menu"` widget](https://www.w3.org/TR/wai-aria/roles#menu), but this is specific to application-like menus which trigger actions or functions. <abbr title="Accessible Rich Internet Applications">ARIA</abbr> menus can only contain menu items, checkbox menu items, radio button menu items, radio button groups, and sub-menus.
Bootstrap's dropdowns, on the other hand, are designed to be generic and applicable to a variety of situations and markup structures. For instance, it is possible to create dropdowns that contain additional inputs and form controls, such as search fields or login forms. For this reason, Bootstrap does not expect (nor automatically add) any of the `role` and `aria-` attributes required for true <abbr title="Accessible Rich Internet Applications">ARIA</abbr> menus. Authors will have to include these more specific attributes themselves.
However, Bootstrap does add built-in support for most standard keyboard menu interactions, such as the ability to move through individual `.dropdown-item` elements using the cursor keys and close the menu with the <kbd>ESC</kbd> key.
## Examples
Wrap the dropdown's toggle (your button or link) and the dropdown menu within `.dropdown`, or another element that declares `position: relative;`. Dropdowns can be triggered from `<a>` or `<button>` elements to better fit your potential needs.
### Single button dropdowns
Any single `.btn` can be turned into a dropdown toggle with some markup changes. Here's how you can put them to work with either `<button>` elements:
{% example html %}
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown button
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</div>
{% endexample %}
And with `<a>` elements:
{% example html %}
<div class="dropdown show">
<a class="btn btn-secondary dropdown-toggle" href="#" role="button" id="dropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown link
</a>
<div class="dropdown-menu" aria-labelledby="dropdownMenuLink">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</div>
{% endexample %}
The best part is you can do this with any button variant, too:
<div class="bd-example">
<div class="btn-group">
<button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Primary</button>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Action</a>

<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Separated link</a>
</div>
</div><!-- /btn-group -->
</div>
{% highlight html %}
<!-- Example single danger button -->
<div class="btn-group">
<button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Action
</button>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Separated link</a>
</div>
</div>
{% endhighlight %}
### Split button dropdowns
Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of `.dropdown-toggle-split` for proper spacing around the dropdown caret.
We use this extra class to reduce the horizontal `padding` on either side of the caret by 25% and remove the `margin-left` that's added for regular button dropdowns. Those extra changes keep the caret centered in the split button and provide a more appropriately sized hit area next to the main button.
<div class="bd-example">
<div class="btn-group">
<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-primary dropdown-toggle dropdown-toggle-split" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

{% endhighlight %}
## Dropup variation
Trigger dropdown menus above elements by adding `.dropup` to the parent element.

## Dropright variation
Trigger dropdown menus at the right of the elements by adding `.dropright` to the parent element.

## Dropleft variation
Trigger dropdown menus at the left of the elements by adding `.dropleft` to the parent element.
<div class="bd-example">
<div class="btn-group dropleft">
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

<button type="button" class="btn btn-secondary">
Split dropleft

{% endhighlight %}
## Menu items
Historically dropdown menu contents *had* to be links, but that's no longer the case with v4. Now you can optionally use `<button>` elements in your dropdowns instead of just `<a>`s.
{% example html %}
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenu2" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenu2">
<button class="dropdown-item" type="button">Action</button>
<button class="dropdown-item" type="button">Another action</button>
<button class="dropdown-item" type="button">Something else here</button>
</div>
</div>
{% endexample %}
## Menu alignment
By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. Add `.dropdown-menu-right` to a `.dropdown-menu` to right align the dropdown menu.
{% callout info %}
**Heads up!** Dropdowns are positioned thanks to Popper.js (except when they are contained in a navbar).
{% endcallout %}

<div class="btn-group">
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Right-aligned menu
</button>
<div class="dropdown-menu dropdown-menu-right">
<button class="dropdown-item" type="button">Action</button>
<button class="dropdown-item" type="button">Another action</button>
<button class="dropdown-item" type="button">Something else here</button>
</div>
</div>
{% endexample %}
## Menu headers
Add a header to label sections of actions in any dropdown menu.
{% example html %}
<div class="dropdown-menu">
<h6 class="dropdown-header">Dropdown header</h6>
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
</div>
{% endexample %}
## Menu dividers
Separate groups of related menu items with a divider.
{% example html %}
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Separated link</a>
</div>
{% endexample %}
## Menu forms
Put a form within a dropdown menu, or make it into a dropdown menu, and use [margin or padding utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) to give it the negative space you require.
{% example html %}
<div class="dropdown-menu">
<form class="px-4 py-3">
<div class="form-group">
<label for="exampleDropdownFormEmail1">Email address</label>
<input type="email" class="form-control" id="exampleDropdownFormEmail1" placeholder="email@example.com">
</div>
<div class="form-group">
<label for="exampleDropdownFormPassword1">Password</label>
<input type="password" class="form-control" id="exampleDropdownFormPassword1" placeholder="Password">
</div>
<div class="form-check">
<input type="checkbox" class="form-check-input" id="dropdownCheck">
<label class="form-check-label" for="dropdownCheck">
Remember me
</label>
</div>
<button type="submit" class="btn btn-primary">Sign in</button>
</form>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">New around here? Sign up</a>
<a class="dropdown-item" href="#">Forgot password?</a>
</div>
{% endexample %}
{% example html %}
<form class="dropdown-menu p-4">
<div class="form-group">
<label for="exampleDropdownFormEmail2">Email address</label>
<input type="email" class="form-control" id="exampleDropdownFormEmail2" placeholder="email@example.com">
</div>
<div class="form-group">
<label for="exampleDropdownFormPassword2">Password</label>
<input type="password" class="form-control" id="exampleDropdownFormPassword2" placeholder="Password">
</div>
<div class="form-check">
<input type="checkbox" class="form-check-input" id="dropdownCheck2">
<label class="form-check-label" for="dropdownCheck2">
Remember me
</label>
</div>
<button type="submit" class="btn btn-primary">Sign in</button>
</form>
{% endexample %}
## Active menu items
Add `.active` to items in the dropdown to **style them as active**.
{% example html %}
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Regular link</a>
<a class="dropdown-item active" href="#">Active link</a>
<a class="dropdown-item" href="#">Another link</a>
</div>
{% endexample %}
## Disabled menu items
Add `.disabled` to items in the dropdown to **style them as disabled**.
{% example html %}
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Regular link</a>
<a class="dropdown-item disabled" href="#">Disabled link</a>
<a class="dropdown-item" href="#">Another link</a>
</div>
{% endexample %}
## Usage
Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the `.show` class on the parent list item. The `data-toggle="dropdown"` attribute is relied on for closing dropdown menus at an application level, so it's a good idea to always use it.
{% callout info %}
On touch-enabled devices, opening a dropdown adds empty (`$.noop`) `mouseover` handlers to the immediate children of the `<body>` element. This admittedly ugly hack is necessary to work around a [quirk in iOS' event delegation](https://www.quirksmode.org/blog/archives/2014/02/mouse_event_bub.html), which would otherwise prevent a tap anywhere outside of the dropdown from triggering the code that closes the dropdown. Once the dropdown is closed, these additional empty `mouseover` handlers are removed.
{% endcallout %}
### Via data attributes
Add `data-toggle="dropdown"` to a link or button to toggle a dropdown.
{% highlight html %}
<div class="dropdown">
<button id="dLabel" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown trigger
</button>
<div class="dropdown-menu" aria-labelledby="dLabel">
...
</div>
</div>
{% endhighlight %}
### Via JavaScript
Call the dropdowns via JavaScript:
{% highlight js %}
$('.dropdown-toggle').dropdown()
{% endhighlight %}
{% callout info %}
##### `data-toggle="dropdown"` still required
Regardless of whether you call your dropdown via JavaScript or instead use the data-api, `data-toggle="dropdown"` is always required to be present on the dropdown's trigger element.
{% endcallout %}
### Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-offset=""`.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 100px;">Name</th>
<th style="width: 100px;">Type</th>
<th style="width: 50px;">Default</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>offset</td>
<td>number | string | function</td>
<td>0</td>
<td>Offset of the dropdown relative to its target. For more information refer to Popper.js's <a href="https://popper.js.org/popper-documentation.html#modifiers..offset.offset">offset docs</a>.</td>
</tr>
<tr>
<td>flip</td>
<td>boolean</td>
<td>true</td>
<td>Allow Dropdown to flip in case of an overlapping on the reference element. For more information refer to Popper.js's <a href="https://popper.js.org/popper-documentation.html#modifiers..flip.enabled">flip docs</a>.</td>
</tr>
<tr>
<td>boundary</td>
<td>string | element</td>
<td>'scrollParent'</td>
<td>Overflow constraint boundary of the dropdown menu. Accepts the values of <code>'viewport'</code>, <code>'window'</code>, <code>'scrollParent'</code>, or an HTMLElement reference (JavaScript only). For more information refer to Popper.js's <a href="https://popper.js.org/popper-documentation.html#modifiers..preventOverflow.boundariesElement">preventOverflow docs</a>.</td>
</tr>
</tbody>
</table>
Note when `boundary` is set to any value other than `'scrollParent'`, the style `position: static` is applied to the `.dropdown` container.
### Methods
| Method | Description |
| --- | --- |
| `$().dropdown('toggle')` | Toggles the dropdown menu of a given navbar or tabbed navigation. |
| `$().dropdown('update')` | Updates the position of an element's dropdown. |
| `$().dropdown('dispose')` | Destroys an element's dropdown. |
### Events
All dropdown events are fired at the `.dropdown-menu`'s parent element and have a `relatedTarget` property, whose value is the toggling anchor element.
| Event | Description |
| --- | --- |
| `show.bs.dropdown` | This event fires immediately when the show instance method is called. |
| `shown.bs.dropdown` | This event is fired when the dropdown has been made visible to the user (will wait for CSS transitions, to complete). |
| `hide.bs.dropdown` | This event is fired immediately when the hide instance method has been called. |
| `hidden.bs.dropdown`| This event is fired when the dropdown has finished being hidden from the user (will wait for CSS transitions, to complete). |
{% highlight js %}
$('#myDropdown').on('show.bs.dropdown', function () {
// do something…
})
{% endhighlight %}

title: Input group
description: Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs.
group: components
toc: true
---
## Basic example
Place one add-on or button on either side of an input. You may also place one on both sides of an input. **We do not support multiple form-controls in a single input group** and `<label>`s must come outside the input group.
{% example html %}
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text" id="basic-addon1">@</span>
</div>
<input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>
<div class="input-group mb-3">
<input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
<div class="input-group-append">
<span class="input-group-text" id="basic-addon2">@example.com</span>
</div>
</div>
<label for="basic-url">Your vanity URL</label>
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text" id="basic-addon3">https://example.com/users/</span>
</div>
<input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text">$</span>
</div>
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
<div class="input-group-append">
<span class="input-group-text">.00</span>
</div>
</div>
<div class="input-group">
<div class="input-group-prepend">
<span class="input-group-text">With textarea</span>
</div>
<textarea class="form-control" aria-label="With textarea"></textarea>
</div>
{% endexample %}
## Sizing
Add the relative form sizing classes to the `.input-group` itself and contents within will automatically resize—no need for repeating the form control size classes on each element.
**Sizing on the individual input group elements isn't supported.**
{% example html %}
<div class="input-group input-group-sm mb-3">
<div class="input-group-prepend">
<span class="input-group-text" id="inputGroup-sizing-sm">Small</span>
</div>
<input type="text" class="form-control" aria-label="Small" aria-describedby="inputGroup-sizing-sm">
</div>
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text" id="inputGroup-sizing-default">Default</span>
</div>
<input type="text" class="form-control" aria-label="Default" aria-describedby="inputGroup-sizing-default">
</div>
<div class="input-group input-group-lg">
<div class="input-group-prepend">
<span class="input-group-text" id="inputGroup-sizing-lg">Large</span>
</div>
<input type="text" class="form-control" aria-label="Large" aria-describedby="inputGroup-sizing-sm">
</div>
{% endexample %}
## Checkboxes and radios
Place any checkbox or radio option within an input group's addon instead of text.
{% example html %}
<div class="input-group mb-3">
<div class="input-group-prepend">
<div class="input-group-text">
<input type="checkbox" aria-label="Checkbox for following text input">
</div>
</div>
<input type="text" class="form-control" aria-label="Text input with checkbox">
</div>
<div class="input-group">
<div class="input-group-prepend">
<div class="input-group-text">
<input type="radio" aria-label="Radio button for following text input">
</div>
</div>
<input type="text" class="form-control" aria-label="Text input with radio button">
</div>
{% endexample %}
## Multiple inputs
While multiple `<input>`s are supported visually, validation styles are only available for input groups with a single `<input>`.
{% example html %}
<div class="input-group">
<div class="input-group-prepend">
<span class="input-group-text" id="">First and last name</span>
</div>
<input type="text" class="form-control">
<input type="text" class="form-control">
</div>
{% endexample %}
## Multiple addons
Multiple add-ons are supported and can be mixed with checkbox and radio input versions.
{% example html %}
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text">$</span>
<span class="input-group-text">0.00</span>
</div>
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
</div>
<div class="input-group">
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
<div class="input-group-append">
<span class="input-group-text">$</span>
<span class="input-group-text">0.00</span>
</div>
</div>
{% endexample %}
## Button addons
{% example html %}
<div class="input-group mb-3">
<div class="input-group-prepend">
<button class="btn btn-outline-secondary" type="button">Button</button>
</div>
<input type="text" class="form-control" placeholder="" aria-label="" aria-describedby="basic-addon1">
</div>
<div class="input-group mb-3">
<input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
<div class="input-group-append">
<button class="btn btn-outline-secondary" type="button">Button</button>

<input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
<div class="input-group-append">
<button class="btn btn-outline-secondary" type="button">Button</button>
<button class="btn btn-outline-secondary" type="button">Button</button>

## Accessibility
Screen readers will have trouble with your forms if you don't include a label for every input. For these input groups, ensure that any additional label or functionality is conveyed to assistive technologies.
The exact technique to be used (`<label>` elements hidden using the `.sr-only` class, or use of the `aria-label` and `aria-labelledby` attributes, possibly in combination with `aria-describedby`) and what additional information will need to be conveyed will vary depending on the exact type of interface widget you're implementing. The examples in this section provide a few suggested, case-specific approaches.

description: Lightweight, flexible component for showcasing hero unit style content.
group: components
---
A lightweight, flexible component that can optionally extend the entire viewport to showcase key marketing messages on your site.
{% example html %}
<div class="jumbotron">
<h1 class="display-4">Hello, world!</h1>
<p class="lead">This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.</p>
<hr class="my-4">
<p>It uses utility classes for typography and spacing to space content out within the larger container.</p>
<p class="lead">
<a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a>
</p>
</div>
{% endexample %}
To make the jumbotron full width, and without rounded corners, add the `.jumbotron-fluid` modifier class and add a `.container` or `.container-fluid` within.
{% example html %}
<div class="jumbotron jumbotron-fluid">
<div class="container">
<h1 class="display-4">Fluid jumbotron</h1>
<p class="lead">This is a modified jumbotron that occupies the entire horizontal space of its parent.</p>

layout: docs
title: List group
description: List groups are a flexible and powerful component for displaying a series of content. Modify and extend them to support just about any content within.
group: components
toc: true
---
## Basic example
The most basic list group is an unordered list with list items and the proper classes. Build upon it with the options that follow, or with your own CSS as needed.
{% example html %}
<ul class="list-group">
<li class="list-group-item">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>
<li class="list-group-item">Morbi leo risus</li>
<li class="list-group-item">Porta ac consectetur ac</li>
<li class="list-group-item">Vestibulum at eros</li>
</ul>
{% endexample %}
## Active items
Add `.active` to a `.list-group-item` to indicate the current active selection.
{% example html %}
<ul class="list-group">
<li class="list-group-item active">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>
<li class="list-group-item">Morbi leo risus</li>
<li class="list-group-item">Porta ac consectetur ac</li>
<li class="list-group-item">Vestibulum at eros</li>
</ul>
{% endexample %}
## Disabled items
Add `.disabled` to a `.list-group-item` to make it _appear_ disabled. Note that some elements with `.disabled` will also require custom JavaScript to fully disable their click events (e.g., links).
{% example html %}
<ul class="list-group">
<li class="list-group-item disabled">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>
<li class="list-group-item">Morbi leo risus</li>
<li class="list-group-item">Porta ac consectetur ac</li>
<li class="list-group-item">Vestibulum at eros</li>
</ul>
{% endexample %}
## Links and buttons
Use `<a>`s or `<button>`s to create _actionable_ list group items with hover, disabled, and active states by adding `.list-group-item-action`. We separate these pseudo-classes to ensure list groups made of non-interactive elements (like `<li>`s or `<div>`s) don't provide a click or tap affordance.
Be sure to **not use the standard `.btn` classes here**.
{% example html %}
<div class="list-group">
<a href="#" class="list-group-item list-group-item-action active">
Cras justo odio
</a>
<a href="#" class="list-group-item list-group-item-action">Dapibus ac facilisis in</a>
<a href="#" class="list-group-item list-group-item-action">Morbi leo risus</a>
<a href="#" class="list-group-item list-group-item-action">Porta ac consectetur ac</a>
<a href="#" class="list-group-item list-group-item-action disabled">Vestibulum at eros</a>
</div>
{% endexample %}
With `<button>`s, you can also make use of the `disabled` attribute instead of the `.disabled` class. Sadly, `<a>`s don't support the disabled attribute.
{% example html %}
<div class="list-group">
<button type="button" class="list-group-item list-group-item-action active">
Cras justo odio
</button>
<button type="button" class="list-group-item list-group-item-action">Dapibus ac facilisis in</button>
<button type="button" class="list-group-item list-group-item-action">Morbi leo risus</button>
<button type="button" class="list-group-item list-group-item-action">Porta ac consectetur ac</button>
<button type="button" class="list-group-item list-group-item-action" disabled>Vestibulum at eros</button>
</div>
{% endexample %}
## Flush
Add `.list-group-flush` to remove some borders and rounded corners to render list group items edge-to-edge in a parent container (e.g., cards).
{% example html %}
<ul class="list-group list-group-flush">
<li class="list-group-item">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>
<li class="list-group-item">Morbi leo risus</li>
<li class="list-group-item">Porta ac consectetur ac</li>
<li class="list-group-item">Vestibulum at eros</li>
</ul>
{% endexample %}
## Contextual classes
Use contextual classes to style list items with a stateful background and color.
{% example html %}
<ul class="list-group">
<li class="list-group-item">Dapibus ac facilisis in</li>
{% for color in site.data.theme-colors %}
<li class="list-group-item list-group-item-{{ color.name }}">This is a {{ color.name }} list group item</li>{% endfor %}
</ul>
{% endexample %}
Contextual classes also work with `.list-group-item-action`. Note the addition of the hover styles here not present in the previous example. Also supported is the `.active` state; apply it to indicate an active selection on a contextual list group item.
{% example html %}
<div class="list-group">
<a href="#" class="list-group-item list-group-item-action">Dapibus ac facilisis in</a>
{% for color in site.data.theme-colors %}
<a href="#" class="list-group-item list-group-item-action list-group-item-{{ color.name }}">This is a {{ color.name }} list group item</a>{% endfor %}
</div>
{% endexample %}
{% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %}
{{ callout-include | markdownify }}
## With badges
Add badges to any list group item to show unread counts, activity, and more with the help of some [utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/).
{% example html %}
<ul class="list-group">
<li class="list-group-item d-flex justify-content-between align-items-center">
Cras justo odio
<span class="badge badge-primary badge-pill">14</span>
</li>
<li class="list-group-item d-flex justify-content-between align-items-center">
Dapibus ac facilisis in
<span class="badge badge-primary badge-pill">2</span>
</li>
<li class="list-group-item d-flex justify-content-between align-items-center">
Morbi leo risus
<span class="badge badge-primary badge-pill">1</span>
</li>
</ul>
{% endexample %}
## Custom content
Add nearly any HTML within, even for linked list groups like the one below, with the help of [flexbox utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/).
{% example html %}
<div class="list-group">
<a href="#" class="list-group-item list-group-item-action flex-column align-items-start active">
<div class="d-flex w-100 justify-content-between">
<h5 class="mb-1">List group item heading</h5>
<small>3 days ago</small>
</div>
<p class="mb-1">Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
<small>Donec id elit non mi porta.</small>
</a>
<a href="#" class="list-group-item list-group-item-action flex-column align-items-start">
<div class="d-flex w-100 justify-content-between">
<h5 class="mb-1">List group item heading</h5>
<small class="text-muted">3 days ago</small>
</div>
<p class="mb-1">Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
<small class="text-muted">Donec id elit non mi porta.</small>
</a>
<a href="#" class="list-group-item list-group-item-action flex-column align-items-start">
<div class="d-flex w-100 justify-content-between">
<h5 class="mb-1">List group item heading</h5>
<small class="text-muted">3 days ago</small>
</div>
<p class="mb-1">Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
<small class="text-muted">Donec id elit non mi porta.</small>
</a>
</div>

## JavaScript behavior
Use the tab JavaScript plugin—include it individually or through the compiled `bootstrap.js` file—to extend our list group to create tabbable panes of local content.
<div class="bd-example" role="tabpanel">
<div class="row">
<div class="col-4">
<div class="list-group" id="list-tab" role="tablist">
<a class="list-group-item list-group-item-action active" id="list-home-list" data-toggle="tab" href="#list-home" role="tab" aria-controls="list-home">Home</a>

{% endhighlight %}
### Using data attributes
You can activate a list group navigation without writing any JavaScript by simply specifying `data-toggle="list"` or on an element. Use these data attributes on `.list-group-item`.
<div role="tabpanel">
{% highlight html %}
<!-- List group -->
<div class="list-group" id="myList" role="tablist">
<a class="list-group-item list-group-item-action active" data-toggle="list" href="#home" role="tab">Home</a>
<a class="list-group-item list-group-item-action" data-toggle="list" href="#profile" role="tab">Profile</a>
<a class="list-group-item list-group-item-action" data-toggle="list" href="#messages" role="tab">Messages</a>
<a class="list-group-item list-group-item-action" data-toggle="list" href="#settings" role="tab">Settings</a>
</div>
<!-- Tab panes -->
<div class="tab-content">
<div class="tab-pane active" id="home" role="tabpanel">...</div>
<div class="tab-pane" id="profile" role="tabpanel">...</div>
<div class="tab-pane" id="messages" role="tabpanel">...</div>
<div class="tab-pane" id="settings" role="tabpanel">...</div>
</div>
{% endhighlight %}
</div>
### Via JavaScript
Enable tabbable list item via JavaScript (each list item needs to be activated individually):
{% highlight js %}
$('#myList a').on('click', function (e) {
e.preventDefault()
$(this).tab('show')
})
{% endhighlight %}
You can activate individual list item in several ways:
{% highlight js %}
$('#myList a[href="#profile"]').tab('show') // Select tab by name
$('#myList a:first-child').tab('show') // Select first tab
$('#myList a:last-child').tab('show') // Select last tab
$('#myList a:nth-child(3)').tab('show') // Select third tab
{% endhighlight %}
### Fade effect
To make tabs panel fade in, add `.fade` to each `.tab-pane`. The first tab pane must also have `.show` to make the initial content visible.
{% highlight html %}
<div class="tab-content">
<div class="tab-pane fade show active" id="home" role="tabpanel">...</div>
<div class="tab-pane fade" id="profile" role="tabpanel">...</div>
<div class="tab-pane fade" id="messages" role="tabpanel">...</div>
<div class="tab-pane fade" id="settings" role="tabpanel">...</div>
</div>
{% endhighlight %}
### Methods
#### $().tab
Activates a list item element and content container. Tab should have either a `data-target` or an `href` targeting a container node in the DOM.
{% highlight html %}
<div class="list-group" id="myList" role="tablist">
<a class="list-group-item list-group-item-action active" data-toggle="list" href="#home" role="tab">Home</a>
<a class="list-group-item list-group-item-action" data-toggle="list" href="#profile" role="tab">Profile</a>
<a class="list-group-item list-group-item-action" data-toggle="list" href="#messages" role="tab">Messages</a>
<a class="list-group-item list-group-item-action" data-toggle="list" href="#settings" role="tab">Settings</a>
</div>
<div class="tab-content">
<div class="tab-pane active" id="home" role="tabpanel">...</div>
<div class="tab-pane" id="profile" role="tabpanel">...</div>
<div class="tab-pane" id="messages" role="tabpanel">...</div>
<div class="tab-pane" id="settings" role="tabpanel">...</div>
</div>
<script>
$(function () {
$('#myList a:last-child').tab('show')
})
</script>
{% endhighlight %}
#### .tab('show')
Selects the given list item and shows its associated pane. Any other list item that was previously selected becomes unselected and its associated pane is hidden. **Returns to the caller before the tab pane has actually been shown** (for example, before the `shown.bs.tab` event occurs).
{% highlight js %}
$('#someListItem').tab('show')
{% endhighlight %}
### Events
When showing a new tab, the events fire in the following order:
1. `hide.bs.tab` (on the current active tab)
2. `show.bs.tab` (on the to-be-shown tab)
3. `hidden.bs.tab` (on the previous active tab, the same one as for the `hide.bs.tab` event)
4. `shown.bs.tab` (on the newly-active just-shown tab, the same one as for the `show.bs.tab` event)
If no tab was already active, the `hide.bs.tab` and `hidden.bs.tab` events will not be fired.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 150px;">Event type</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>show.bs.tab</td>
<td>This event fires on tab show, but before the new tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>
</tr>
<tr>
<td>shown.bs.tab</td>
<td>This event fires on tab show after a tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>
</tr>
<tr>
<td>hide.bs.tab</td>
<td>This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use <code>event.target</code> and <code>event.relatedTarget</code> to target the current active tab and the new soon-to-be-active tab, respectively.</td>
</tr>
<tr>
<td>hidden.bs.tab</td>
<td>This event fires after a new tab is shown (and thus the previous active tab is hidden). Use <code>event.target</code> and <code>event.relatedTarget</code> to target the previous active tab and the new active tab, respectively.</td>
</tr>
</tbody>
</table>
{% highlight js %}
$('a[data-toggle="list"]').on('shown.bs.tab', function (e) {
e.target // newly activated tab
e.relatedTarget // previous active tab
})
{% endhighlight %}

title: Modal
description: Use Bootstrap's JavaScript modal plugin to add dialogs to your site for lightboxes, user notifications, or completely custom content.
group: components
toc: true
---
## How it works
Before getting started with Bootstrap's modal component, be sure to read the following as our menu options have recently changed.
- Modals are built with HTML, CSS, and JavaScript. They're positioned over everything else in the document and remove scroll from the `<body>` so that modal content scrolls instead.
- Clicking on the modal "backdrop" will automatically close the modal.
- Bootstrap only supports one modal window at a time. Nested modals aren't supported as we believe them to be poor user experiences.
- Modals use `position: fixed`, which can sometimes be a bit particular about its rendering. Whenever possible, place your modal HTML in a top-level position to avoid potential interference from other elements. You'll likely run into issues when nesting a `.modal` within another fixed element.
- Once again, due to `position: fixed`, there are some caveats with using modals on mobile devices. [See our browser support docs]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/browsers-devices/#modals-and-dropdowns-on-mobile) for details.
- Due to how HTML5 defines its semantics, [the `autofocus` HTML attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#attr-autofocus) has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript:
{% highlight js %}
$('#myModal').on('shown.bs.modal', function () {
$('#myInput').trigger('focus')
})
{% endhighlight %}
Keep reading for demos and usage guidelines.
## Examples
### Modal components
Below is a _static_ modal example (meaning its `position` and `display` have been overridden). Included are the modal header, modal body (required for `padding`), and modal footer (optional). We ask that you include modal headers with dismiss actions whenever possible, or provide another explicit dismiss action.
<div class="bd-example bd-example-modal">
<div class="modal" tabindex="-1" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">
<p>Modal body text goes here.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</div>
{% highlight html %}
<div class="modal" tabindex="-1" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">

</button>
</div>
<div class="modal-body">

<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
{% endhighlight %}
### Live demo
Toggle a working modal demo by clicking the button below. It will slide down and fade in from the top of the page.
<div id="exampleModalLive" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="exampleModalLiveLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLiveLabel">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">
<p>Woohoo, you're reading this text in a modal!</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
<div class="bd-example">
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalLive">
Launch demo modal
</button>
</div>
{% highlight html %}
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">

</div>
<div class="modal-footer">

<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
{% endhighlight %}
### Scrolling long content
When modals become too long for the user's viewport or device, they scroll independent of the page itself. Try the demo below to see what we mean.
<div id="exampleModalLong" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">

### Tooltips and popovers
[Tooltips]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/tooltips/) and [popovers]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/popovers/) can be placed within modals as needed. When modals are closed, any tooltips and popovers within are also automatically dismissed.

### Using the grid
Utilize the Bootstrap grid system within a modal by nesting `.container-fluid` within the `.modal-body`. Then, use the normal grid system classes as you would anywhere else.
<div id="gridSystemModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="gridModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="gridModalLabel">Grids in modals</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
</div>
<div class="modal-body">
<div class="container-fluid bd-example-row">

### Varying modal content
Have a bunch of buttons that all trigger the same modal with slightly different contents? Use `event.relatedTarget` and [HTML `data-*` attributes](https://developer.mozilla.org/en-US/docs/Learn/HTML/Howto/Use_data_attributes) (possibly [via jQuery](https://api.jquery.com/data/)) to vary the contents of the modal depending on which button was clicked.
Below is a live demo followed by example HTML and JavaScript. For more information, [read the modal events docs](#events) for details on `relatedTarget`.
{% example html %}
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@mdo">Open modal for @mdo</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@fat">Open modal for @fat</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@getbootstrap">Open modal for @getbootstrap</button>
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">New message</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">
<form>
<div class="form-group">
<label for="recipient-name" class="col-form-label">Recipient:</label>
<input type="text" class="form-control" id="recipient-name">
</div>
<div class="form-group">
<label for="message-text" class="col-form-label">Message:</label>
<textarea class="form-control" id="message-text"></textarea>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Send message</button>
</div>
</div>
</div>
</div>
{% endexample %}
{% highlight js %}
$('#exampleModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget) // Button that triggered the modal
var recipient = button.data('whatever') // Extract info from data-* attributes
// If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
// Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
var modal = $(this)
modal.find('.modal-title').text('New message to ' + recipient)
modal.find('.modal-body input').val(recipient)
})
{% endhighlight %}
### Remove animation
For modals that simply appear rather than fade in to view, remove the `.fade` class from your modal markup.
{% highlight html %}
<div class="modal" tabindex="-1" role="dialog" aria-labelledby="..." aria-hidden="true">
...
</div>
{% endhighlight %}
### Dynamic heights
If the height of a modal changes while it is open, you should call `$('#myModal').modal('handleUpdate')` to readjust the modal's position in case a scrollbar appears.
### Accessibility
Be sure to add `role="dialog"` and `aria-labelledby="..."`, referencing the modal title, to `.modal`, and `role="document"` to the `.modal-dialog` itself. Additionally, you may give a description of your modal dialog with `aria-describedby` on `.modal`.
### Embedding YouTube videos
Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. [See this helpful Stack Overflow post](https://stackoverflow.com/questions/18622508/bootstrap-3-and-youtube-in-modal) for more information.
## Optional sizes
Modals have two optional sizes, available via modifier classes to be placed on a `.modal-dialog`. These sizes kick in at certain breakpoints to avoid horizontal scrollbars on narrower viewports.
<div class="bd-example">
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bd-example-modal-lg">Large modal</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bd-example-modal-sm">Small modal</button>
</div>
{% highlight html %}
<!-- Large modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bd-example-modal-lg">Large modal</button>
<div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
...
</div>
</div>
</div>
<!-- Small modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bd-example-modal-sm">Small modal</button>
<div class="modal fade bd-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
<div class="modal-dialog modal-sm">
<div class="modal-content">
...
</div>
</div>
</div>
{% endhighlight %}
<div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="myLargeModalLabel">Large modal</h4>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">
...
</div>
</div>
</div>
</div>
<div class="modal fade bd-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
<div class="modal-dialog modal-sm">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="mySmallModalLabel">Small modal</h4>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">
...
</div>
</div>
</div>
</div>
## Usage
The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds `.modal-open` to the `<body>` to override default scrolling behavior and generates a `.modal-backdrop` to provide a click area for dismissing shown modals when clicking outside the modal.
### Via data attributes
Activate a modal without writing JavaScript. Set `data-toggle="modal"` on a controller element, like a button, along with a `data-target="#foo"` or `href="#foo"` to target a specific modal to toggle.
{% highlight html %}
<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
{% endhighlight %}
### Via JavaScript
Call a modal with id `myModal` with a single line of JavaScript:
{% highlight js %}$('#myModal').modal(options){% endhighlight %}
### Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-backdrop=""`.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 100px;">Name</th>
<th style="width: 50px;">Type</th>
<th style="width: 50px;">Default</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>backdrop</td>
<td>boolean or the string <code>'static'</code></td>
<td>true</td>
<td>Includes a modal-backdrop element. Alternatively, specify <code>static</code> for a backdrop which doesn't close the modal on click.</td>
</tr>
<tr>
<td>keyboard</td>
<td>boolean</td>
<td>true</td>
<td>Closes the modal when escape key is pressed</td>
</tr>
<tr>
<td>focus</td>
<td>boolean</td>
<td>true</td>
<td>Puts the focus on the modal when initialized.</td>
</tr>
<tr>
<td>show</td>
<td>boolean</td>
<td>true</td>
<td>Shows the modal when initialized.</td>
</tr>
</tbody>
</table>
### Methods
{% capture callout-include %}{% include callout-danger-async-methods.md %}{% endcapture %}
{{ callout-include | markdownify }}
#### `.modal(options)`
Activates your content as a modal. Accepts an optional options `object`.
{% highlight js %}
$('#myModal').modal({
keyboard: false
})
{% endhighlight %}
#### `.modal('toggle')`
Manually toggles a modal. **Returns to the caller before the modal has actually been shown or hidden** (i.e. before the `shown.bs.modal` or `hidden.bs.modal` event occurs).
{% highlight js %}$('#myModal').modal('toggle'){% endhighlight %}
#### `.modal('show')`
Manually opens a modal. **Returns to the caller before the modal has actually been shown** (i.e. before the `shown.bs.modal` event occurs).
{% highlight js %}$('#myModal').modal('show'){% endhighlight %}
#### `.modal('hide')`
Manually hides a modal. **Returns to the caller before the modal has actually been hidden** (i.e. before the `hidden.bs.modal` event occurs).
{% highlight js %}$('#myModal').modal('hide'){% endhighlight %}
#### `.modal('handleUpdate')`
Manually readjust the modal's position if the height of a modal changes while it is open (i.e. in case a scrollbar appears).
{% highlight js %}$('#myModal').modal('handleUpdate'){% endhighlight %}
#### `.modal('dispose')`
Destroys an element's modal.
### Events
Bootstrap's modal class exposes a few events for hooking into modal functionality. All modal events are fired at the modal itself (i.e. at the `<div class="modal">`).
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 150px;">Event Type</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>show.bs.modal</td>
<td>This event fires immediately when the <code>show</code> instance method is called. If caused by a click, the clicked element is available as the <code>relatedTarget</code> property of the event.</td>
</tr>
<tr>
<td>shown.bs.modal</td>
<td>This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the <code>relatedTarget</code> property of the event.</td>
</tr>
<tr>
<td>hide.bs.modal</td>
<td>This event is fired immediately when the <code>hide</code> instance method has been called.</td>
</tr>
<tr>
<td>hidden.bs.modal</td>
<td>This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).</td>
</tr>
</tbody>
</table>
{% highlight js %}
$('#myModal').on('hidden.bs.modal', function (e) {
// do something...
})
{% endhighlight %}

group: components
toc: true

## How it works
Here's what you need to know before getting started with the navbar:
- Navbars require a wrapping `.navbar` with `.navbar-expand{-sm|-md|-lg|-xl}` for responsive collapsing and [color scheme](#color-schemes) classes.
- Navbars and their contents are fluid by default. Use [optional containers](#containers) to limit their horizontal width.
- Use our [spacing]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) and [flex]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/) utility classes for controlling spacing and alignment within navbars.
- Navbars are responsive by default, but you can easily modify them to change that. Responsive behavior depends on our Collapse JavaScript plugin.
- Navbars are hidden by default when printing. Force them to be printed by adding `.d-print` to the `.navbar`. See the [display]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/display/) utility class.
- Ensure accessibility by using a `<nav>` element or, if using a more generic element such as a `<div>`, add a `role="navigation"` to every navbar to explicitly identify it as a landmark region for users of assistive technologies.
Read on for an example and list of supported sub-components.
## Supported content
Navbars come with built-in support for a handful of sub-components. Choose from the following as needed:
- `.navbar-brand` for your company, product, or project name.
- `.navbar-nav` for a full-height and lightweight navigation (including support for dropdowns).
- `.navbar-toggler` for use with our collapse plugin and other [navigation toggling](#responsive-behaviors) behaviors.
- `.form-inline` for any form controls and actions.
- `.navbar-text` for adding vertically centered strings of text.
- `.collapse.navbar-collapse` for grouping and hiding navbar contents by a parent breakpoint.
Here's an example of all the sub-components included in a responsive light-themed navbar that automatically collapses at the `lg` (large) breakpoint.
{% example html %}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdown">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</div>
</nav>
{% endexample %}
This example uses [color]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/colors/) (`bg-light`) and [spacing]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) (`my-2`, `my-lg-0`, `mr-sm-0`, `my-sm-0`) utility classes.
### Brand
The `.navbar-brand` can be applied to most elements, but an anchor works best as some elements might require utility classes or custom styles.
{% example html %}
<!-- As a link -->
<nav class="navbar navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
</nav>
<!-- As a heading -->
<nav class="navbar navbar-light bg-light">
<span class="navbar-brand mb-0 h1">Navbar</span>
</nav>
{% endexample %}
Adding images to the `.navbar-brand` will likely always require custom styles or utilities to properly size. Here are some examples to demonstrate.
{% example html %}
<!-- Just an image -->
<nav class="navbar navbar-light bg-light">
<a class="navbar-brand" href="#">
<img src="{{ site.baseurl }}/assets/brand/bootstrap-solid.svg" width="30" height="30" alt="">
</a>
</nav>
{% endexample %}
{% example html %}
<!-- Image and text -->
<nav class="navbar navbar-light bg-light">
<a class="navbar-brand" href="#">
<img src="{{ site.baseurl }}/assets/brand/bootstrap-solid.svg" width="30" height="30" class="d-inline-block align-top" alt="">
Bootstrap
</a>
</nav>
{% endexample %}
### Nav
Navbar navigation links build on our `.nav` options with their own modifier class and require the use of [toggler classes](#toggler) for proper responsive styling. **Navigation in navbars will also grow to occupy as much horizontal space as possible** to keep your navbar contents securely aligned.
Active states—with `.active`—to indicate the current page can be applied directly to `.nav-link`s or their immediate parent `.nav-item`s.
{% example html %}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
</div>
</nav>
{% endexample %}
And because we use classes for our navs, you can avoid the list-based approach entirely if you like.
{% example html %}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavAltMarkup">
<div class="navbar-nav">
<a class="nav-item nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
<a class="nav-item nav-link" href="#">Features</a>
<a class="nav-item nav-link" href="#">Pricing</a>
<a class="nav-item nav-link disabled" href="#">Disabled</a>
</div>
</div>
</nav>
{% endexample %}
You may also utilize dropdowns in your navbar nav. Dropdown menus require a wrapping element for positioning, so be sure to use separate and nested elements for `.nav-item` and `.nav-link` as shown below.
{% example html %}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavDropdown">
<ul class="navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown link
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
</ul>
</div>
</nav>
{% endexample %}
### Forms
Place various form controls and components within a navbar with `.form-inline`.
{% example html %}
<nav class="navbar navbar-light bg-light">
<form class="form-inline">
<input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</nav>
{% endexample %}
Align the contents of your inline forms with utilities as needed.
{% example html %}
<nav class="navbar navbar-light bg-light justify-content-between">
<a class="navbar-brand">Navbar</a>
<form class="form-inline">
<input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</nav>
{% endexample %}
Input groups work, too:
{% example html %}
<nav class="navbar navbar-light bg-light">
<form class="form-inline">
<div class="input-group">
<div class="input-group-prepend">
<span class="input-group-text" id="basic-addon1">@</span>
</div>
<input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>
</form>
</nav>
{% endexample %}
Various buttons are supported as part of these navbar forms, too. This is also a great reminder that vertical alignment utilities can be used to align different sized elements.
{% example html %}
<nav class="navbar navbar-light bg-light">
<form class="form-inline">
<button class="btn btn-outline-success" type="button">Main button</button>
<button class="btn btn-sm btn-outline-secondary" type="button">Smaller button</button>
</form>
</nav>
{% endexample %}
### Text
Navbars may contain bits of text with the help of `.navbar-text`. This class adjusts vertical alignment and horizontal spacing for strings of text.
{% example html %}
<nav class="navbar navbar-light bg-light">
<span class="navbar-text">
Navbar text with an inline element
</span>
</nav>
{% endexample %}
Mix and match with other components and utilities as needed.
{% example html %}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar w/ text</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarText">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">

## Color schemes
Theming the navbar has never been easier thanks to the combination of theming classes and `background-color` utilities. Choose from `.navbar-light` for use with light background colors, or `.navbar-dark` for dark background colors. Then, customize with `.bg-*` utilities.
<div class="bd-example">

</nav>
<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
<!-- Navbar content -->
</nav>
{% endhighlight %}
## Containers
Although it's not required, you can wrap a navbar in a `.container` to center it on a page or add one within to only center the contents of a [fixed or static top navbar](#placement).
{% example html %}
<div class="container">
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
</nav>
</div>
{% endexample %}
When the container is within your navbar, its horizontal padding is removed at breakpoints lower than your specified `.navbar-expand{-sm|-md|-lg|-xl}` class. This ensures we're not doubling up on padding unnecessarily on lower viewports when your navbar is collapsed.
{% example html %}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container">
<a class="navbar-brand" href="#">Navbar</a>
</div>
</nav>
{% endexample %}
## Placement
Use our [position utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/position/) to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, or stickied to the top (scrolls with the page until it reaches the top, then stays there). Fixed navbars use `position: fixed`, meaning they're pulled from the normal flow of the DOM and may require custom CSS (e.g., `padding-top` on the `<body>`) to prevent overlap with other elements.
Also note that **`.sticky-top` uses `position: sticky`, which [isn't fully supported in every browser](https://caniuse.com/#feat=css-sticky)**.
{% example html %}
<nav class="navbar navbar-light bg-light">
<a class="navbar-brand" href="#">Default</a>
</nav>
{% endexample %}
{% example html %}
<nav class="navbar fixed-top navbar-light bg-light">
<a class="navbar-brand" href="#">Fixed top</a>
</nav>
{% endexample %}
{% example html %}
<nav class="navbar fixed-bottom navbar-light bg-light">
<a class="navbar-brand" href="#">Fixed bottom</a>
</nav>
{% endexample %}
{% example html %}
<nav class="navbar sticky-top navbar-light bg-light">
<a class="navbar-brand" href="#">Sticky top</a>
</nav>
{% endexample %}
## Responsive behaviors
Navbars can utilize `.navbar-toggler`, `.navbar-collapse`, and `.navbar-expand{-sm|-md|-lg|-xl}` classes to change when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.
For navbars that never collapse, add the `.navbar-expand` class on the navbar. For navbars that always collapse, don't add any `.navbar-expand` class.
### Toggler
Navbar togglers are left-aligned by default, but should they follow a sibling element like a `.navbar-brand`, they'll automatically be aligned to the far right. Reversing your markup will reverse the placement of the toggler. Below are examples of different toggle styles.
With no `.navbar-brand` shown in lowest breakpoint:
{% example html %}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarTogglerDemo01">
<a class="navbar-brand" href="#">Hidden brand</a>
<ul class="navbar-nav mr-auto mt-2 mt-lg-0">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</div>
</nav>
{% endexample %}
With a brand name shown on the left and toggler on the right:
{% example html %}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo02" aria-controls="navbarTogglerDemo02" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarTogglerDemo02">
<ul class="navbar-nav mr-auto mt-2 mt-lg-0">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" type="search" placeholder="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</div>
</nav>
{% endexample %}
With a toggler on the left and brand name on the right:
{% example html %}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo03" aria-controls="navbarTogglerDemo03" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<div class="collapse navbar-collapse" id="navbarTogglerDemo03">
<ul class="navbar-nav mr-auto mt-2 mt-lg-0">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</div>
</nav>
{% endexample %}
### External content
Sometimes you want to use the collapse plugin to trigger hidden content elsewhere on the page. Because our plugin works on the `id` and `data-target` matching, that's easily done!
{% example html %}
<div class="pos-f-t">
<div class="collapse" id="navbarToggleExternalContent">
<div class="bg-dark p-4">
<h4 class="text-white">Collapsed content</h4>
<span class="text-muted">Toggleable via the navbar brand.</span>
</div>
</div>
<nav class="navbar navbar-dark bg-dark">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
</nav>
</div>
{% endexample %}

## Base nav
Navigation available in Bootstrap share general markup and styles, from the base `.nav` class to the active and disabled states. Swap modifier classes to switch between each style.
The base `.nav` component is built with flexbox and provide a strong foundation for building all types of navigation components. It includes some style overrides (for working with lists), some link padding for larger hit areas, and basic disabled styling.
{% callout info %}
The base `.nav` component does not include any `.active` state. The following examples include the class, mainly to demonstrate that this particular class does not trigger any special styling.
{% endcallout %}
{% example html %}
<ul class="nav">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
{% endexample %}
Classes are used throughout, so your markup can be super flexible. Use `<ul>`s like above, or roll your own with say a `<nav>` element. Because the `.nav` uses `display: flex`, the nav links behave the same as nav items would, but without the extra markup.
{% example html %}
<nav class="nav">
<a class="nav-link active" href="#">Active</a>
<a class="nav-link" href="#">Link</a>
<a class="nav-link" href="#">Link</a>
<a class="nav-link disabled" href="#">Disabled</a>
</nav>
{% endexample %}
## Available styles
Change the style of `.nav`s component with modifiers and utilities. Mix and match as needed, or build your own.
### Horizontal alignment
Change the horizontal alignment of your nav with [flexbox utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/layout/grid/#horizontal-alignment). By default, navs are left-aligned, but you can easily change them to center or right aligned.
Centered with `.justify-content-center`:
{% example html %}
<ul class="nav justify-content-center">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
{% endexample %}
Right-aligned with `.justify-content-end`:
{% example html %}
<ul class="nav justify-content-end">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
{% endexample %}
### Vertical
Stack your navigation by changing the flex item direction with the `.flex-column` utility. Need to stack them on some viewports but not others? Use the responsive versions (e.g., `.flex-sm-column`).
{% example html %}
<ul class="nav flex-column">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
{% endexample %}
As always, vertical navigation is possible without `<ul>`s, too.
{% example html %}
<nav class="nav flex-column">
<a class="nav-link active" href="#">Active</a>
<a class="nav-link" href="#">Link</a>
<a class="nav-link" href="#">Link</a>
<a class="nav-link disabled" href="#">Disabled</a>
</nav>
{% endexample %}
### Tabs
Takes the basic nav from above and adds the `.nav-tabs` class to generate a tabbed interface. Use them to create tabbable regions with our [tab JavaScript plugin](#javascript-behavior).
{% example html %}
<ul class="nav nav-tabs">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
{% endexample %}
### Pills
Take that same HTML, but use `.nav-pills` instead:
{% example html %}
<ul class="nav nav-pills">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
{% endexample %}
### Fill and justify
Force your `.nav`'s contents to extend the full available width one of two modifier classes. To proportionately fill all available space with your `.nav-item`s, use `.nav-fill`. Notice that all horizontal space is occupied, but not every nav item has the same width.
{% example html %}
<ul class="nav nav-pills nav-fill">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Longer nav link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
{% endexample %}
When using a `<nav>`-based navigation, be sure to include `.nav-item` on the anchors.
{% example html %}
<nav class="nav nav-pills nav-fill">
<a class="nav-item nav-link active" href="#">Active</a>
<a class="nav-item nav-link" href="#">Link</a>
<a class="nav-item nav-link" href="#">Link</a>
<a class="nav-item nav-link disabled" href="#">Disabled</a>
</nav>
{% endexample %}
For equal-width elements, use `.nav-justified`. All horizontal space will be occupied by nav links, but unlike the `.nav-fill` above, every nav item will be the same width.
{% example html %}
<nav class="nav nav-pills nav-justified">
<a class="nav-link active" href="#">Active</a>
<a class="nav-link" href="#">Longer nav link</a>
<a class="nav-link" href="#">Link</a>
<a class="nav-link disabled" href="#">Disabled</a>
</nav>
{% endexample %}
Similar to the `.nav-fill` example using a `<nav>`-based navigation, be sure to include `.nav-item` on the anchors.
{% example html %}
<nav class="nav nav-pills nav-justified">
<a class="nav-item nav-link active" href="#">Active</a>
<a class="nav-item nav-link" href="#">Link</a>
<a class="nav-item nav-link" href="#">Link</a>
<a class="nav-item nav-link disabled" href="#">Disabled</a>
</nav>
{% endexample %}
## Working with flex utilities
If you need responsive nav variations, consider using a series of [flexbox utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/). While more verbose, these utilities offer greater customization across responsive breakpoints. In the example below, our nav will be stacked on the lowest breakpoint, then adapt to a horizontal layout that fills the available width starting from the small breakpoint.
{% example html %}
<nav class="nav nav-pills flex-column flex-sm-row">
<a class="flex-sm-fill text-sm-center nav-link active" href="#">Active</a>
<a class="flex-sm-fill text-sm-center nav-link" href="#">Link</a>
<a class="flex-sm-fill text-sm-center nav-link" href="#">Link</a>
<a class="flex-sm-fill text-sm-center nav-link disabled" href="#">Disabled</a>
</nav>
{% endexample %}
## Regarding accessibility
If you're using navs to provide a navigation bar, be sure to add a `role="navigation"` to the most logical parent container of the `<ul>`, or wrap a `<nav>` element around the whole navigation. Do not add the role to the `<ul>` itself, as this would prevent it from being announced as an actual list by assistive technologies.
Note that navigation bars, even if visually styled as tabs with the `.nav-tabs` class, should **not** be given `role="tablist"`, `role="tab"` or `role="tabpanel"` attributes. These are only appropriate for dynamic tabbed interfaces, as described in the [<abbr title="Web Accessibility Initiative">WAI</abbr> <abbr title="Accessible Rich Internet Applications">ARIA</abbr> Authoring Practices](https://www.w3.org/TR/wai-aria-practices/#tabpanel). See [JavaScript behavior](#javascript-behavior) for dynamic tabbed interfaces in this section for an example.
## Using dropdowns
Add dropdown menus with a little extra HTML and the [dropdowns JavaScript plugin]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/dropdowns/#usage).
### Tabs with dropdowns
{% example html %}
<ul class="nav nav-tabs">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Dropdown</a>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Separated link</a>
</div>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
{% endexample %}
### Pills with dropdowns
{% example html %}
<ul class="nav nav-pills">
<li class="nav-item">
<a class="nav-link active" href="#">Active</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Dropdown</a>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Separated link</a>
</div>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
{% endexample %}
## JavaScript behavior
Use the tab JavaScript plugin—include it individually or through the compiled `bootstrap.js` file—to extend our navigational tabs and pills to create tabbable panes of local content, even via dropdown menus.
If you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util).
Dynamic tabbed interfaces, as described in the [<abbr title="Web Accessibility Initiative">WAI</abbr> <abbr title="Accessible Rich Internet Applications">ARIA</abbr> Authoring Practices](https://www.w3.org/TR/wai-aria-practices/#tabpanel), require `role="tablist"`, `role="tab"`, `role="tabpanel"`, and additional `aria-` attributes in order to convey their structure, functionality and current state to users of assistive technologies (such as screen readers).
Note that dynamic tabbed interfaces should <em>not</em> contain dropdown menus, as this causes both usability and accessibility issues. From a usability perspective, the fact that the currently displayed tab's trigger element is not immediately visible (as it's inside the closed dropdown menu) can cause confusion. From an accessibility point of view, there is currently no sensible way to map this sort of construct to a standard WAI ARIA pattern, meaning that it cannot be easily made understandable to users of assistive technologies.

To help fit your needs, this works with `<ul>`-based markup, as shown above, or with any arbitrary "roll your own" markup. Note that if you're using `<nav>`, you shouldn't add `role="tablist"` directly to it, as this would override the element's native role as a navigation landmark. Instead, switch to an alternative element (in the exammple below, a simple `<div>`) and wrap the `<nav>` around it.

{% endhighlight %}
### Using data attributes
You can activate a tab or pill navigation without writing any JavaScript by simply specifying `data-toggle="tab"` or `data-toggle="pill"` on an element. Use these data attributes on `.nav-tabs` or `.nav-pills`.
{% highlight html %}
<!-- Nav tabs -->
<ul class="nav nav-tabs" id="myTab" role="tablist">
<li class="nav-item">
<a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">Profile</a>
</li>
<li class="nav-item">
<a class="nav-link" id="messages-tab" data-toggle="tab" href="#messages" role="tab" aria-controls="messages" aria-selected="false">Messages</a>
</li>
<li class="nav-item">
<a class="nav-link" id="settings-tab" data-toggle="tab" href="#settings" role="tab" aria-controls="settings" aria-selected="false">Settings</a>
</li>
</ul>
<!-- Tab panes -->
<div class="tab-content">
<div class="tab-pane active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
<div class="tab-pane" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
<div class="tab-pane" id="messages" role="tabpanel" aria-labelledby="messages-tab">...</div>
<div class="tab-pane" id="settings" role="tabpanel" aria-labelledby="settings-tab">...</div>
</div>
{% endhighlight %}
### Via JavaScript
Enable tabbable tabs via JavaScript (each tab needs to be activated individually):
{% highlight js %}
$('#myTab a').on('click', function (e) {
e.preventDefault()
$(this).tab('show')
})
{% endhighlight %}
You can activate individual tabs in several ways:
{% highlight js %}
$('#myTab a[href="#profile"]').tab('show') // Select tab by name
$('#myTab li:first-child a').tab('show') // Select first tab
$('#myTab li:last-child a').tab('show') // Select last tab
$('#myTab li:nth-child(3) a').tab('show') // Select third tab
{% endhighlight %}
### Fade effect
To make tabs fade in, add `.fade` to each `.tab-pane`. The first tab pane must also have `.show` to make the initial content visible.
{% highlight html %}
<div class="tab-content">
<div class="tab-pane fade show active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
<div class="tab-pane fade" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
<div class="tab-pane fade" id="messages" role="tabpanel" aria-labelledby="messages-tab">...</div>
<div class="tab-pane fade" id="settings" role="tabpanel" aria-labelledby="settings-tab">...</div>
</div>
{% endhighlight %}
### Methods
{% capture callout-include %}{% include callout-danger-async-methods.md %}{% endcapture %}
{{ callout-include | markdownify }}
#### $().tab
Activates a tab element and content container. Tab should have either a `data-target` or an `href` targeting a container node in the DOM.
{% highlight html %}
<ul class="nav nav-tabs" id="myTab" role="tablist">
<li class="nav-item">
<a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">Profile</a>
</li>
<li class="nav-item">
<a class="nav-link" id="messages-tab" data-toggle="tab" href="#messages" role="tab" aria-controls="messages" aria-selected="false">Messages</a>
</li>
<li class="nav-item">
<a class="nav-link" id="settings-tab" data-toggle="tab" href="#settings" role="tab" aria-controls="settings" aria-selected="false">Settings</a>
</li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
<div class="tab-pane" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
<div class="tab-pane" id="messages" role="tabpanel" aria-labelledby="messages-tab">...</div>
<div class="tab-pane" id="settings" role="tabpanel" aria-labelledby="settings-tab">...</div>
</div>
<script>
$(function () {
$('#myTab li:last-child a').tab('show')
})
</script>
{% endhighlight %}
#### .tab('show')
Selects the given tab and shows its associated pane. Any other tab that was previously selected becomes unselected and its associated pane is hidden. **Returns to the caller before the tab pane has actually been shown** (i.e. before the `shown.bs.tab` event occurs).
{% highlight js %}
$('#someTab').tab('show')
{% endhighlight %}
#### .tab('dispose')
Destroys an element's tab.
### Events
When showing a new tab, the events fire in the following order:
1. `hide.bs.tab` (on the current active tab)
2. `show.bs.tab` (on the to-be-shown tab)
3. `hidden.bs.tab` (on the previous active tab, the same one as for the `hide.bs.tab` event)
4. `shown.bs.tab` (on the newly-active just-shown tab, the same one as for the `show.bs.tab` event)
If no tab was already active, then the `hide.bs.tab` and `hidden.bs.tab` events will not be fired.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 150px;">Event Type</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>show.bs.tab</td>
<td>This event fires on tab show, but before the new tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>
</tr>
<tr>
<td>shown.bs.tab</td>
<td>This event fires on tab show after a tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>
</tr>
<tr>
<td>hide.bs.tab</td>
<td>This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use <code>event.target</code> and <code>event.relatedTarget</code> to target the current active tab and the new soon-to-be-active tab, respectively.</td>
</tr>
<tr>
<td>hidden.bs.tab</td>
<td>This event fires after a new tab is shown (and thus the previous active tab is hidden). Use <code>event.target</code> and <code>event.relatedTarget</code> to target the previous active tab and the new active tab, respectively.</td>
</tr>
</tbody>
</table>
{% highlight js %}
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
e.target // newly activated tab
e.relatedTarget // previous active tab
})

title: Pagination
description: Documentation and examples for showing pagination to indicate a series of related content exists across multiple pages.
group: components
toc: true
---
## Overview
We use a large block of connected links for our pagination, making links hard to miss and easily scalable—all while providing large hit areas. Pagination is built with list HTML elements so screen readers can announce the number of available links. Use a wrapping `<nav>` element to identify it as a navigation section to screen readers and other assistive technologies.
In addition, as pages likely have more than one such navigation section, it's advisable to provide a descriptive `aria-label` for the `<nav>` to reflect its purpose. For example, if the pagination component is used to navigate between a set of search results, an appropriate label could be `aria-label="Search results pages"`.
{% example html %}
<nav aria-label="Page navigation example">
<ul class="pagination">
<li class="page-item"><a class="page-link" href="#">Previous</a></li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item"><a class="page-link" href="#">Next</a></li>
</ul>
</nav>
{% endexample %}
## Working with icons
Looking to use an icon or symbol in place of text for some pagination links? Be sure to provide proper screen reader support with `aria` attributes and the `.sr-only` utility.
{% example html %}
<nav aria-label="Page navigation example">
<ul class="pagination">
<li class="page-item">
<a class="page-link" href="#" aria-label="Previous">
<span aria-hidden="true">&laquo;</span>
<span class="sr-only">Previous</span>
</a>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#" aria-label="Next">
<span aria-hidden="true">&raquo;</span>
<span class="sr-only">Next</span>
</a>
</li>
</ul>
</nav>
{% endexample %}
## Disabled and active states
Pagination links are customizable for different circumstances. Use `.disabled` for links that appear un-clickable and `.active` to indicate the current page.
While the `.disabled` class uses `pointer-events: none` to _try_ to disable the link functionality of `<a>`s, that CSS property is not yet standardized and doesn't account for keyboard navigation. As such, you should always add `tabindex="-1"` on disabled links and use custom JavaScript to fully disable their functionality.
{% example html %}
<nav aria-label="...">
<ul class="pagination">
<li class="page-item disabled">
<a class="page-link" href="#" tabindex="-1">Previous</a>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item active">
<a class="page-link" href="#">2 <span class="sr-only">(current)</span></a>
</li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#">Next</a>
</li>
</ul>
</nav>
{% endexample %}
You can optionally swap out active or disabled anchors for `<span>`, or omit the anchor in the case of the prev/next arrows, to remove click functionality and prevent keyboard focus while retaining intended styles.
{% example html %}
<nav aria-label="...">
<ul class="pagination">
<li class="page-item disabled">
<span class="page-link">Previous</span>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item active">
<span class="page-link">
2
<span class="sr-only">(current)</span>
</span>
</li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#">Next</a>
</li>
</ul>
</nav>
{% endexample %}
## Sizing
Fancy larger or smaller pagination? Add `.pagination-lg` or `.pagination-sm` for additional sizes.
{% example html %}
<nav aria-label="...">
<ul class="pagination pagination-lg">
<li class="page-item disabled">
<a class="page-link" href="#" tabindex="-1">1</a>
</li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
</ul>
</nav>
{% endexample %}
{% example html %}
<nav aria-label="...">
<ul class="pagination pagination-sm">
<li class="page-item disabled">
<a class="page-link" href="#" tabindex="-1">1</a>
</li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
</ul>
</nav>
{% endexample %}
## Alignment
Change the alignment of pagination components with [flexbox utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/).
{% example html %}
<nav aria-label="Page navigation example">
<ul class="pagination justify-content-center">
<li class="page-item disabled">
<a class="page-link" href="#" tabindex="-1">Previous</a>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#">Next</a>
</li>
</ul>
</nav>
{% endexample %}
{% example html %}
<nav aria-label="Page navigation example">
<ul class="pagination justify-content-end">
<li class="page-item disabled">
<a class="page-link" href="#" tabindex="-1">Previous</a>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>

title: Popovers
description: Documentation and examples for adding Bootstrap popovers, like those found in iOS, to any element on your site.
group: components
toc: true
---
## Overview
Things to know when using the popover plugin:
- Popovers rely on the 3rd party library [Popper.js](https://popper.js.org/) for positioning. You must include [popper.min.js]({{ site.cdn.popper }}) before bootstrap.js or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper.js in order for popovers to work!
- Popovers require the [tooltip plugin]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/tooltips/) as a dependency.
- If you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util).
- Popovers are opt-in for performance reasons, so **you must initialize them yourself**.
- Zero-length `title` and `content` values will never show a popover.
- Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
- Triggering popovers on hidden elements will not work.
- Popovers for `.disabled` or `disabled` elements must be triggered on a wrapper element.
- When triggered from anchors that wrap across multiple lines, popovers will be centered between the anchors' overall width. Use `white-space: nowrap;` on your `<a>`s to avoid this behavior.
- Popovers must be hidden before their corresponding elements have been removed from the DOM.
Keep reading to see how popovers work with some examples.
## Example: Enable popovers everywhere
One way to initialize all popovers on a page would be to select them by their `data-toggle` attribute:
{% highlight js %}
$(function () {
$('[data-toggle="popover"]').popover()
})
{% endhighlight %}
## Example: Using the `container` option
When you have some styles on a parent element that interfere with a popover, you'll want to specify a custom `container` so that the popover's HTML appears within that element instead.
{% highlight js %}
$(function () {
$('.example-popover').popover({
container: 'body'
})
})
{% endhighlight %}
## Example
{% example html %}
<button type="button" class="btn btn-lg btn-danger" data-toggle="popover" title="Popover title" data-content="And here's some amazing content. It's very engaging. Right?">Click to toggle popover</button>
{% endexample %}
### Four directions
Four options are available: top, right, bottom, and left aligned.
<div class="bd-example popover-demo">
<div class="bd-example-popovers">
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="top" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
Popover on top
</button>
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="right" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
Popover on right
</button>
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
Popover on bottom
</button>
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="left" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
Popover on left
</button>
</div>
</div>
{% highlight html %}
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="top" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
Popover on top
</button>
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="right" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
Popover on right
</button>
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Vivamus
sagittis lacus vel augue laoreet rutrum faucibus.">
Popover on bottom
</button>
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="left" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
Popover on left
</button>
{% endhighlight %}
### Dismiss on next click
Use the `focus` trigger to dismiss popovers on the user's next click of a different element than the toggle element.
{% callout danger %}
#### Specific markup required for dismiss-on-next-click
For proper cross-browser and cross-platform behavior, you must use the `<a>` tag, _not_ the `<button>` tag, and you also must include a [`tabindex`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/tabindex) attribute.
{% endcallout %}
{% example html %}
<a tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" data-trigger="focus" title="Dismissible popover" data-content="And here's some amazing content. It's very engaging. Right?">Dismissible popover</a>
{% endexample %}
{% highlight js %}
$('.popover-dismiss').popover({
trigger: 'focus'
})
{% endhighlight %}
### Disabled elements
Elements with the `disabled` attribute aren't interactive, meaning users cannot hover or click them to trigger a popover (or tooltip). As a workaround, you'll want to trigger the popover from a wrapper `<div>` or `<span>` and override the `pointer-events` on the disabled element.
For disabled popover triggers, you may also prefer `data-trigger="hover"` so that the popover appears as immediate visual feedback to your users as they may not expect to _click_ on a disabled element.
{% example html %}
<span class="d-inline-block" data-toggle="popover" data-content="Disabled popover">
<button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
</span>
{% endexample %}
## Usage
Enable popovers via JavaScript:
{% highlight js %}$('#example').popover(options){% endhighlight %}
### Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-animation=""`.
<table class="table table-bordered table-striped">

{% callout info %}
#### Data attributes for individual popovers
Options for individual popovers can alternatively be specified through the use of data attributes, as explained above.
{% endcallout %}
### Methods
{% capture callout-include %}{% include callout-danger-async-methods.md %}{% endcapture %}
{{ callout-include | markdownify }}
#### `$().popover(options)`
Initializes popovers for an element collection.
#### `.popover('show')`
Reveals an element's popover. **Returns to the caller before the popover has actually been shown** (i.e. before the `shown.bs.popover` event occurs). This is considered a "manual" triggering of the popover. Popovers whose both title and content are zero-length are never displayed.
{% highlight js %}$('#element').popover('show'){% endhighlight %}
#### `.popover('hide')`
Hides an element's popover. **Returns to the caller before the popover has actually been hidden** (i.e. before the `hidden.bs.popover` event occurs). This is considered a "manual" triggering of the popover.
{% highlight js %}$('#element').popover('hide'){% endhighlight %}
#### `.popover('toggle')`
Toggles an element's popover. **Returns to the caller before the popover has actually been shown or hidden** (i.e. before the `shown.bs.popover` or `hidden.bs.popover` event occurs). This is considered a "manual" triggering of the popover.
{% highlight js %}$('#element').popover('toggle'){% endhighlight %}
#### `.popover('dispose')`
Hides and destroys an element's popover. Popovers that use delegation (which are created using [the `selector` option](#options)) cannot be individually destroyed on descendant trigger elements.
{% highlight js %}$('#element').popover('dispose'){% endhighlight %}
#### `.popover('enable')`
Gives an element's popover the ability to be shown. **Popovers are enabled by default.**
{% highlight js %}$('#element').popover('enable'){% endhighlight %}
#### `.popover('disable')`
Removes the ability for an element's popover to be shown. The popover will only be able to be shown if it is re-enabled.
{% highlight js %}$('#element').popover('disable'){% endhighlight %}
#### `.popover('toggleEnabled')`
Toggles the ability for an element's popover to be shown or hidden.
{% highlight js %}$('#element').popover('toggleEnabled'){% endhighlight %}
#### `.popover('update')`
Updates the position of an element's popover.
{% highlight js %}$('#element').popover('update'){% endhighlight %}
### Events
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 150px;">Event Type</th>
<th>Description</th>

</thead>
<tbody>
<tr>
<td>show.bs.popover</td>
<td>This event fires immediately when the <code>show</code> instance method is called.</td>

layout: docs
title: Progress
description: Documentation and examples for using Bootstrap custom progress bars featuring support for stacked bars, animated backgrounds, and text labels.
group: components
toc: true
---
## How it works
Progress components are built with two HTML elements, some CSS to set the width, and a few attributes. We don't use [the HTML5 `<progress>` element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/progress), ensuring you can stack progress bars, animate them, and place text labels over them.
- We use the `.progress` as a wrapper to indicate the max value of the progress bar.
- We use the inner `.progress-bar` to indicate the progress so far.
- The `.progress-bar` requires an inline style, utility class, or custom CSS to set their width.
- The `.progress-bar` also requires some `role` and `aria` attributes to make it accessible.
Put that all together, and you have the following examples.
{% example html %}
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endexample %}
Bootstrap provides a handful of [utilities for setting width]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/sizing/). Depending on your needs, these may help with quickly configuring progress.
{% example html %}
<div class="progress">
<div class="progress-bar w-75" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endexample %}
## Labels
Add labels to your progress bars by placing text within the `.progress-bar`.
{% example html %}
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">25%</div>
</div>
{% endexample %}
## Height
We only set a `height` value on the `.progress`, so if you change that value the inner `.progress-bar` will automatically resize accordingly.
{% example html %}
<div class="progress" style="height: 1px;">
<div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress" style="height: 20px;">
<div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endexample %}
## Backgrounds
Use background utility classes to change the appearance of individual progress bars.
{% example html %}
<div class="progress">
<div class="progress-bar bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endexample %}
## Multiple bars
Include multiple progress bars in a progress component if you need.
{% example html %}
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 15%" aria-valuenow="15" aria-valuemin="0" aria-valuemax="100"></div>
<div class="progress-bar bg-success" role="progressbar" style="width: 30%" aria-valuenow="30" aria-valuemin="0" aria-valuemax="100"></div>
<div class="progress-bar bg-info" role="progressbar" style="width: 20%" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endexample %}
## Striped
Add `.progress-bar-striped` to any `.progress-bar` to apply a stripe via CSS gradient over the progress bar's background color.
{% example html %}
<div class="progress">
<div class="progress-bar progress-bar-striped" role="progressbar" style="width: 10%" aria-valuenow="10" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-striped bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-striped bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-striped bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-striped bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endexample %}
## Animated stripes
The striped gradient can also be animated. Add `.progress-bar-animated` to `.progress-bar` to animate the stripes right to left via CSS3 animations.
<div class="bd-example">
<div class="progress">
<div class="progress-bar progress-bar-striped" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
</div>
<button type="button" class="btn btn-secondary bd-toggle-animated-progress" data-toggle="button" aria-pressed="false" autocomplete="off">
Toggle animation
</button>
</div>
{% highlight html %}
<div class="progress">
<div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
</div>
{% endhighlight %}

title: Scrollspy
description: Automatically update Bootstrap navigation or list group components based on scroll position to indicate which link is currently active in the viewport.
group: components
toc: true
---
## How it works
Scrollspy has a few requirements to function properly:
- If you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util).
- It must be used on a Bootstrap [nav component]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/navs/) or [list group]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/list-group/).
- Scrollspy requires `position: relative;` on the element you're spying on, usually the `<body>`.
- When spying on elements other than the `<body>`, be sure to have a `height` set and `overflow-y: scroll;` applied.
- Anchors (`<a>`) are required and must point to an element with that `id`.
When successfully implemented, your nav or list group will update accordingly, moving the `.active` class from one item to the next based on their associated targets.
## Example in navbar
Scroll the area below the navbar and watch the active class change. The dropdown items will be highlighted as well.
<div class="bd-example">
<nav id="navbar-example2" class="navbar navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>

## Example with nested nav
Scrollspy also works with nested `.nav`s. If a nested `.nav` is `.active`, its parents will also be `.active`. Scroll the area next to the navbar and watch the active class change.
<div class="bd-example">
<div class="row">
<div class="col-4">
<nav id="navbar-example3" class="navbar navbar-light bg-light flex-column">

## Usage
### Via data attributes
To easily add scrollspy behavior to your topbar navigation, add `data-spy="scroll"` to the element you want to spy on (most typically this would be the `<body>`). Then add the `data-target` attribute with the ID or class of the parent element of any Bootstrap `.nav` component.
{% highlight css %}
body {
position: relative;
}
{% endhighlight %}
{% highlight html %}
<body data-spy="scroll" data-target="#navbar-example">
...
<div id="navbar-example">
<ul class="nav nav-tabs" role="tablist">
...
</ul>
</div>
...
</body>
{% endhighlight %}
### Via JavaScript
After adding `position: relative;` in your CSS, call the scrollspy via JavaScript:
{% highlight js %}
$('body').scrollspy({ target: '#navbar-example' })
{% endhighlight %}
{% callout danger %}
#### Resolvable ID targets required
Navbar links must have resolvable id targets. For example, a `<a href="#home">home</a>` must correspond to something in the DOM like `<div id="home"></div>`.
{% endcallout %}
{% callout info %}
#### Non-`:visible` target elements ignored
Target elements that are not [`:visible` according to jQuery](https://api.jquery.com/visible-selector/) will be ignored and their corresponding nav items will never be highlighted.
{% endcallout %}
### Methods
#### `.scrollspy('refresh')`
When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so:
{% highlight js %}
$('[data-spy="scroll"]').each(function () {
var $spy = $(this).scrollspy('refresh')
})
{% endhighlight %}
#### `.scrollspy('dispose')`
Destroys an element's scrollspy.
### Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-offset=""`.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 100px;">Name</th>
<th style="width: 100px;">Type</th>
<th style="width: 50px;">Default</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>offset</td>
<td>number</td>
<td>10</td>
<td>Pixels to offset from top when calculating position of scroll.</td>
</tr>
</tbody>
</table>
### Events
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 150px;">Event Type</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>activate.bs.scrollspy</td>
<td>This event fires on the scroll element whenever a new item becomes activated by the scrollspy.</td>
</tr>
</tbody>
</table>
{% highlight js %}
$('[data-spy="scroll"]').on('activate.bs.scrollspy', function () {
// do something…
})
{% endhighlight %}

title: Tooltips
description: Documentation and examples for adding custom Bootstrap tooltips with CSS and JavaScript using CSS3 for animations and data-attributes for local title storage.
group: components
toc: true
---
## Overview
Things to know when using the tooltip plugin:
- Tooltips rely on the 3rd party library [Popper.js](https://popper.js.org/) for positioning. You must include [popper.min.js]({{ site.cdn.popper }}) before bootstrap.js or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper.js in order for tooltips to work!
- If you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util).
- Tooltips are opt-in for performance reasons, so **you must initialize them yourself**.
- Tooltips with zero-length titles are never displayed.
- Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
- Triggering tooltips on hidden elements will not work.
- Tooltips for `.disabled` or `disabled` elements must be triggered on a wrapper element.
- When triggered from hyperlinks that span multiple lines, tooltips will be centered. Use `white-space: nowrap;` on your `<a>`s to avoid this behavior.
- Tooltips must be hidden before their corresponding elements have been removed from the DOM.
Got all that? Great, let's see how they work with some examples.
## Example: Enable tooltips everywhere
One way to initialize all tooltips on a page would be to select them by their `data-toggle` attribute:
{% highlight js %}
$(function () {
$('[data-toggle="tooltip"]').tooltip()
})
{% endhighlight %}
## Examples
Hover over the links below to see tooltips:
<div class="bd-example tooltip-demo">
<p class="muted">Tight pants next level keffiyeh <a href="#" data-toggle="tooltip" title="Default tooltip">you probably</a> haven't heard of them. Photo booth beard raw denim letterpress vegan messenger bag stumptown. Farm-to-table seitan, mcsweeney's fixie sustainable quinoa 8-bit american apparel <a href="#" data-toggle="tooltip" title="Another tooltip">have a</a> terry richardson vinyl chambray. Beard stumptown, cardigans banh mi lomo thundercats. Tofu biodiesel williamsburg marfa, four loko mcsweeney's cleanse vegan chambray. A really ironic artisan <a href="#" data-toggle="tooltip" title="Another one here too">whatever keytar</a>, scenester farm-to-table banksy Austin <a href="#" data-toggle="tooltip" title="The last tip!">twitter handle</a> freegan cred raw denim single-origin coffee viral.
</p>
</div>
Hover over the buttons below to see the four tooltips directions: top, right, bottom, and left.
<div class="bd-example tooltip-demo">
<div class="bd-example-tooltips">
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="top" title="Tooltip on top">Tooltip on top</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="right" title="Tooltip on right">Tooltip on right</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">Tooltip on bottom</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="left" title="Tooltip on left">Tooltip on left</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">Tooltip with HTML</button>
</div>
</div>
{% highlight html %}
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="top" title="Tooltip on top">
Tooltip on top
</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="right" title="Tooltip on right">
Tooltip on right
</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">
Tooltip on bottom
</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="left" title="Tooltip on left">
Tooltip on left
</button>
{% endhighlight %}
And with custom HTML added:
{% highlight html %}
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">
Tooltip with HTML
</button>
{% endhighlight %}
## Usage
The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.
Trigger the tooltip via JavaScript:
{% highlight js %}
$('#example').tooltip(options)
{% endhighlight %}
### Markup
The required markup for a tooltip is only a `data` attribute and `title` on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to `top` by the plugin).
{% callout warning %}
##### Making tooltips work for keyboard and assistive technology users
You should only add tooltips to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as `<span>`s) can be made focusable by adding the `tabindex="0"` attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users. In addition, most assistive technologies currently do not announce the tooltip in this situation.
Additionally, do not rely solely on `hover` as the trigger for your tooltip, as this will make your tooltips impossible to trigger for keyboard users.
{% endcallout %}
{% highlight html %}
<!-- HTML to write -->
<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>
<!-- Generated markup by the plugin -->
<div class="tooltip bs-tooltip-top" role="tooltip">
<div class="arrow"></div>
<div class="tooltip-inner">
Some tooltip text!
</div>
</div>
{% endhighlight %}
### Disabled elements
Elements with the `disabled` attribute aren't interactive, meaning users cannot focus, hover, or click them to trigger a tooltip (or popover). As a workaround, you'll want to trigger the tooltip from a wrapper `<div>` or `<span>`, ideally made keyboard-focusable using `tabindex="0"`, and override the `pointer-events` on the disabled element.
<div class="tooltip-demo">
{% example html %}
<span class="d-inline-block" tabindex="0" data-toggle="tooltip" title="Disabled tooltip">
<button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
</span>
{% endexample %}
</div>
### Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-animation=""`.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 100px;">Name</th>

</tr>
<tr>
<td>container</td>
<td>string | element | false</td>
<td>false</td>
<td>
<p>Appends the tooltip to a specific element. Example: <code>container: 'body'</code>. This option is particularly useful in that it allows you to position the tooltip in the flow of the document near the triggering element - which will prevent the tooltip from floating away from the triggering element during a window resize.</p>
</td>

</td>
</tr>
<tr>
<td>html</td>
<td>boolean</td>
<td>false</td>
<td>
<p>Allow HTML in the tooltip.</p>
<p>If true, HTML tags in the tooltip's <code>title</code> will be rendered in the tooltip. If false, jQuery's <code>text</code> method will be used to insert content into the DOM.</p>

</td>
</tr>
<tr>
<td>selector</td>
<td>string | false</td>
<td>false</td>
<td>If a selector is provided, tooltip objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have popovers added.

<td>title</td>
<td>string | element | function</td>
<td>''</td>
<td>
<p>Default title value if <code>title</code> attribute isn't present.</p>

<td>trigger</td>
<td>string</td>
<td>'hover focus'</td>
<td>

<p><code>'hover'</code> on its own will result in tooltips that cannot be triggered via the keyboard, and should only be used if alternative methods for conveying the same information for keyboard users is present.</p>
</td>
</tr>
<tr>
<td>offset</td>
<td>number | string</td>

{% callout info %}
#### Data attributes for individual tooltips
Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above.
{% endcallout %}
### Methods
{% capture callout-include %}{% include callout-danger-async-methods.md %}{% endcapture %}
{{ callout-include | markdownify }}
#### `$().tooltip(options)`
Attaches a tooltip handler to an element collection.
#### `.tooltip('show')`
Reveals an element's tooltip. **Returns to the caller before the tooltip has actually been shown** (i.e. before the `shown.bs.tooltip` event occurs). This is considered a "manual" triggering of the tooltip. Tooltips with zero-length titles are never displayed.
{% highlight js %}$('#element').tooltip('show'){% endhighlight %}
#### `.tooltip('hide')`
Hides an element's tooltip. **Returns to the caller before the tooltip has actually been hidden** (i.e. before the `hidden.bs.tooltip` event occurs). This is considered a "manual" triggering of the tooltip.
{% highlight js %}$('#element').tooltip('hide'){% endhighlight %}
#### `.tooltip('toggle')`
Toggles an element's tooltip. **Returns to the caller before the tooltip has actually been shown or hidden** (i.e. before the `shown.bs.tooltip` or `hidden.bs.tooltip` event occurs). This is considered a "manual" triggering of the tooltip.
{% highlight js %}$('#element').tooltip('toggle'){% endhighlight %}
#### `.tooltip('dispose')`
Hides and destroys an element's tooltip. Tooltips that use delegation (which are created using [the `selector` option](#options)) cannot be individually destroyed on descendant trigger elements.
{% highlight js %}$('#element').tooltip('dispose'){% endhighlight %}
#### `.tooltip('enable')`
Gives an element's tooltip the ability to be shown. **Tooltips are enabled by default.**
{% highlight js %}$('#element').tooltip('enable'){% endhighlight %}
#### `.tooltip('disable')`
Removes the ability for an element's tooltip to be shown. The tooltip will only be able to be shown if it is re-enabled.
{% highlight js %}$('#element').tooltip('disable'){% endhighlight %}
#### `.tooltip('toggleEnabled')`
Toggles the ability for an element's tooltip to be shown or hidden.
{% highlight js %}$('#element').tooltip('toggleEnabled'){% endhighlight %}
#### `.tooltip('update')`
Updates the position of an element's tooltip.
{% highlight js %}$('#element').tooltip('update'){% endhighlight %}

## Inline code
Wrap inline snippets of code with `<code>`. Be sure to escape HTML angle brackets.
{% example html %}
For example, <code>&lt;section&gt;</code> should be wrapped as inline.
{% endexample %}
## Code blocks
Use `<pre>`s for multiple lines of code. Once again, be sure to escape any angle brackets in the code for proper rendering. You may optionally add the `.pre-scrollable` class, which will set a max-height of 350px and provide a y-axis scrollbar.
{% example html %}
<pre><code>&lt;p&gt;Sample text here...&lt;/p&gt;
&lt;p&gt;And another line of sample text here...&lt;/p&gt;
</code></pre>
{% endexample %}
## Variables
For indicating variables use the `<var>` tag.
{% example html %}
<var>y</var> = <var>m</var><var>x</var> + <var>b</var>
{% endexample %}
## User input
Use the `<kbd>` to indicate input that is typically entered via keyboard.
{% example html %}
To switch directories, type <kbd>cd</kbd> followed by the name of the directory.<br>
To edit settings, press <kbd><kbd>ctrl</kbd> + <kbd>,</kbd></kbd>
{% endexample %}
## Sample output
For indicating sample output from a program use the `<samp>` tag.
{% example html %}
<samp>This text is meant to be treated as sample output from a computer program.</samp>
{% endexample %}

title: Figures
description: Documentation and examples for displaying related images and text with the figure component in Bootstrap.
group: content
---
Anytime you need to display a piece of content—like an image with an optional caption, consider using a `<figure>`.
Use the included `.figure` , `.figure-img` and `.figure-caption` classes to provide some baseline styles for the HTML5 `<figure>` and `<figcaption>` elements. Images in figures have no explicit size, so be sure to add the `.img-fluid` class to your `<img>` to make it responsive.
{% example html %}
<figure class="figure">
<img data-src="holder.js/400x300" class="figure-img img-fluid rounded" alt="A generic square placeholder image with rounded corners in a figure.">
<figcaption class="figure-caption">A caption for the above image.</figcaption>
</figure>
{% endexample %}
Aligning the figure's caption is easy with our [text utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/#text-alignment).
{% example html %}
<figure class="figure">
<img data-src="holder.js/400x300" class="figure-img img-fluid rounded" alt="A generic square placeholder image with rounded corners in a figure.">
<figcaption class="figure-caption text-right">A caption for the above image.</figcaption>
</figure>

title: Images
description: Documentation and examples for opting images into responsive behavior (so they never become larger than their parent elements) and add lightweight styles to them—all via classes.
group: content
toc: true
---
## Responsive images
Images in Bootstrap are made responsive with `.img-fluid`. `max-width: 100%;` and `height: auto;` are applied to the image so that it scales with the parent element.
<div class="bd-example">
<img data-src="holder.js/100px250" class="img-fluid" alt="Generic responsive image">
</div>
{% highlight html %}
<img src="..." class="img-fluid" alt="Responsive image">
{% endhighlight %}
{% callout warning %}
##### SVG images and IE 10
In Internet Explorer 10, SVG images with `.img-fluid` are disproportionately sized. To fix this, add `width: 100% \9;` where necessary. This fix improperly sizes other image formats, so Bootstrap doesn't apply it automatically.
{% endcallout %}
## Image thumbnails
In addition to our [border-radius utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/borders/), you can use `.img-thumbnail` to give an image a rounded 1px border appearance.
<div class="bd-example bd-example-images">
<img data-src="holder.js/200x200" class="img-thumbnail" alt="A generic square placeholder image with a white border around it, making it resemble a photograph taken with an old instant camera">
</div>
{% highlight html %}
<img src="..." alt="..." class="img-thumbnail">
{% endhighlight %}
## Aligning images
Align images with the [helper float classes]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/float) or [text alignment classes]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/#text-alignment). `block`-level images can be centered using [the `.mx-auto` margin utility class]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/#horizontal-centering).
<div class="bd-example bd-example-images">
<img data-src="holder.js/200x200" class="rounded float-left" alt="A generic square placeholder image with rounded corners">
<img data-src="holder.js/200x200" class="rounded float-right" alt="A generic square placeholder image with rounded corners">
</div>
{% highlight html %}
<img src="..." class="rounded float-left" alt="...">
<img src="..." class="rounded float-right" alt="...">
{% endhighlight %}
<div class="bd-example bd-example-images">
<img data-src="holder.js/200x200" class="rounded mx-auto d-block" alt="A generic square placeholder image with rounded corners">
</div>
{% highlight html %}
<img src="..." class="rounded mx-auto d-block" alt="...">
{% endhighlight %}
<div class="bd-example bd-example-images">
<div class="text-center">
<img data-src="holder.js/200x200" class="rounded" alt="A generic square placeholder image with rounded corners">
</div>
</div>
{% highlight html %}
<div class="text-center">
<img src="..." class="rounded" alt="...">
</div>
{% endhighlight %}
## Picture
If you are using the `<picture>` element to specify multiple `<source>` elements for a specific `<img>`, make sure to add the `.img-*` classes to the `<img>` and not to the `<picture>` tag.
{% highlight html %}
<picture>
<source srcset="..." type="image/svg+xml">
<img src="..." class="img-fluid img-thumbnail" alt="...">
</picture>
{% endhighlight %}

title: Reboot
description: Reboot, a collection of element-specific CSS changes in a single file, kickstart Bootstrap to provide an elegant, consistent, and simple baseline to build upon.
group: content
redirect_from: "/docs/4.0/content/"
toc: true
---
## Approach
Reboot builds upon Normalize, providing many HTML elements with somewhat opinionated styles using only element selectors. Additional styling is done only with classes. For example, we reboot some `<table>` styles for a simpler baseline and later provide `.table`, `.table-bordered`, and more.
Here are our guidelines and reasons for choosing what to override in Reboot:
- Update some browser default values to use `rem`s instead of `em`s for scalable component spacing.
- Avoid `margin-top`. Vertical margins can collapse, yielding unexpected results. More importantly though, a single direction of `margin` is a simpler mental model.
- For easier scaling across device sizes, block elements should use `rem`s for `margin`s.
- Keep declarations of `font`-related properties to a minimum, using `inherit` whenever possible.
## Page defaults
The `<html>` and `<body>` elements are updated to provide better page-wide defaults. More specifically:
- The `box-sizing` is globally set on every element—including `*::before` and `*::after`, to `border-box`. This ensures that the declared width of element is never exceeded due to padding or border.
- No base `font-size` is declared on the `<html>`, but `16px` is assumed (the browser default). `font-size: 1rem` is applied on the `<body>` for easy responsive type-scaling via media queries while respecting user preferences and ensuring a more accessible approach.
- The `<body>` also sets a global `font-family`, `line-height`, and `text-align`. This is inherited later by some form elements to prevent font inconsistencies.
- For safety, the `<body>` has a declared `background-color`, defaulting to `#fff`.
## Native font stack
The default web fonts (Helvetica Neue, Helvetica, and Arial) have been dropped in Bootstrap 4 and replaced with a "native font stack" for optimum text rendering on every device and OS. Read more about [native font stacks in this *Smashing Magazine* article](https://www.smashingmagazine.com/2015/11/using-system-ui-fonts-practical-guide/).
{% highlight sass %}
$font-family-sans-serif:
// Safari for OS X and iOS (San Francisco)
-apple-system,
// Chrome < 56 for OS X (San Francisco)
BlinkMacSystemFont,
// Windows
"Segoe UI",
// Android
"Roboto",
// Basic web fallback
"Helvetica Neue", Arial, sans-serif,
// Emoji fonts
"Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol" !default;
{% endhighlight %}
This `font-family` is applied to the `<body>` and automatically inherited globally throughout Bootstrap. To switch the global `font-family`, update `$font-family-base` and recompile Bootstrap.
## Headings and paragraphs
All heading elementse.g., `<h1>`and `<p>` are reset to have their `margin-top` removed. Headings have `margin-bottom: .5rem` added and paragraphs `margin-bottom: 1rem` for easy spacing.
<table>
<thead>
<tr>
<th>Heading</th>
<th>Example</th>
</tr>
</thead>
<tbody>
<tr>
<td>
{% markdown %}`<h1></h1>`{% endmarkdown %}
</td>
<td><span class="h1">h1. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h2></h2>`{% endmarkdown %}
</td>
<td><span class="h2">h2. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h3></h3>`{% endmarkdown %}
</td>
<td><span class="h3">h3. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h4></h4>`{% endmarkdown %}
</td>
<td><span class="h4">h4. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h5></h5>`{% endmarkdown %}
</td>
<td><span class="h5">h5. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h6></h6>`{% endmarkdown %}
</td>
<td><span class="h6">h6. Bootstrap heading</span></td>
</tr>
</tbody>
</table>
## Lists
All lists—`<ul>`, `<ol>`, and `<dl>`—have their `margin-top` removed and a `margin-bottom: 1rem`. Nested lists have no `margin-bottom`.
<div class="bd-example">
{% markdown %}
* Lorem ipsum dolor sit amet
* Consectetur adipiscing elit
* Integer molestie lorem at massa
* Facilisis in pretium nisl aliquet
* Nulla volutpat aliquam velit
* Phasellus iaculis neque
* Purus sodales ultricies
* Vestibulum laoreet porttitor sem
* Ac tristique libero volutpat at
* Faucibus porta lacus fringilla vel
* Aenean sit amet erat nunc
* Eget porttitor lorem
1. Lorem ipsum dolor sit amet
2. Consectetur adipiscing elit
3. Integer molestie lorem at massa
4. Facilisis in pretium nisl aliquet
5. Nulla volutpat aliquam velit
6. Faucibus porta lacus fringilla vel
7. Aenean sit amet erat nunc
8. Eget porttitor lorem
{% endmarkdown %}
</div>
For simpler styling, clear hierarchy, and better spacing, description lists have updated `margin`s. `<dd>`s reset `margin-left` to `0` and add `margin-bottom: .5rem`. `<dt>`s are **bolded**.
<div class="bd-example">
{% markdown %}
<dl>
<dt>Description lists</dt>
<dd>A description list is perfect for defining terms.</dd>
<dt>Euismod</dt>
<dd>Vestibulum id ligula porta felis euismod semper eget lacinia odio sem.</dd>
<dd>Donec id elit non mi porta gravida at eget metus.</dd>
<dt>Malesuada porta</dt>
<dd>Etiam porta sem malesuada magna mollis euismod.</dd>
</dl>
{% endmarkdown %}
</div>
## Preformatted text
The `<pre>` element is reset to remove its `margin-top` and use `rem` units for its `margin-bottom`.
<div class="bd-example">
{% markdown %}
<pre>
.example-element {
margin-bottom: 1rem;
}
</pre>
{% endmarkdown %}
</div>
## Tables
Tables are slightly adjusted to style `<caption>`s, collapse borders, and ensure consistent `text-align` throughout. Additional changes for borders, padding, and more come with [the `.table` class]({{ site.baseurl }}/docs/{{ site.docs_version }}/content/tables/).
<div class="bd-example">
<table>
<caption>
This is an example table, and this is its caption to describe the contents.
</caption>
<thead>
<tr>
<th>Table heading</th>
<th>Table heading</th>
<th>Table heading</th>
<th>Table heading</th>
</tr>
</thead>
<tbody>
<tr>
<td>Table cell</td>
<td>Table cell</td>
<td>Table cell</td>
<td>Table cell</td>
</tr>
<tr>
<td>Table cell</td>
<td>Table cell</td>
<td>Table cell</td>
<td>Table cell</td>
</tr>
<tr>
<td>Table cell</td>
<td>Table cell</td>
<td>Table cell</td>
<td>Table cell</td>
</tr>
</tbody>
</table>
</div>
## Forms
Various form elements have been rebooted for simpler base styles. Here are some of the most notable changes:
- `<fieldset>`s have no borders, padding, or margin so they can be easily used as wrappers for individual inputs or groups of inputs.
- `<legend>`s, like fieldsets, have also been restyled to be displayed as a heading of sorts.
- `<label>`s are set to `display: inline-block` to allow `margin` to be applied.
- `<input>`s, `<select>`s, `<textarea>`s, and `<button>`s are mostly addressed by Normalize, but Reboot removes their `margin` and sets `line-height: inherit`, too.
- `<textarea>`s are modified to only be resizable vertically as horizontal resizing often "breaks" page layout.
These changes, and more, are demonstrated below.
<form class="bd-example">
<fieldset>
<legend>Example legend</legend>
<p>
<label for="input">Example input</label>
<input type="text" id="input" placeholder="Example input">
</p>
<p>
<label for="select">Example select</label>
<select id="select">
<option value="">Choose...</option>
<optgroup label="Option group 1">
<option value="">Option 1</option>
<option value="">Option 2</option>
<option value="">Option 3</option>
</optgroup>
<optgroup label="Option group 2">
<option value="">Option 4</option>
<option value="">Option 5</option>
<option value="">Option 6</option>
</optgroup>
</select>
</p>
<p>
<label>
<input type="checkbox" value="">
Check this checkbox
</label>
</p>
<p>
<label>
<input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
Option one is this and that
</label>
<label>
<input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
Option two is something else that's also super long to demonstrate the wrapping of these fancy form controls.
</label>
<label>
<input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled>
Option three is disabled
</label>
</p>
<p>
<label for="textarea">Example textarea</label>
<textarea id="textarea" rows="3"></textarea>

<p>
<label for="date">Example date</label>
<input type="date" id="date">
</p>
<p>
<label for="time">Example time</label>
<input type="time" id="time">
</p>
<p>
<label for="output">Example output</label>
<output name="result" id="output">100</output>

<input type="submit" value="Input submit button">
<input type="button" value="Input button">

<p>
<button type="submit" disabled>Button submit</button>
<input type="submit" value="Input submit button" disabled>
<input type="button" value="Input button" disabled>
</p>
</fieldset>
</form>
## Misc elements
### Address
The `<address>` element is updated to reset the browser default `font-style` from `italic` to `normal`. `line-height` is also now inherited, and `margin-bottom: 1rem` has been added. `<address>`s are for presenting contact information for the nearest ancestor (or an entire body of work). Preserve formatting by ending lines with `<br>`.
<div class="bd-example">
<address>
<strong>Twitter, Inc.</strong><br>
1355 Market St, Suite 900<br>
San Francisco, CA 94103<br>
<abbr title="Phone">P:</abbr> (123) 456-7890
</address>
<address>
<strong>Full Name</strong><br>
<a href="mailto:#">first.last@example.com</a>
</address>
</div>
### Blockquote
The default `margin` on blockquotes is `1em 40px`, so we reset that to `0 0 1rem` for something more consistent with other elements.
<div class="bd-example">
<blockquote class="blockquote">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
<footer>Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>
</div>
### Inline elements
The `<abbr>` element receives basic styling to make it stand out amongst paragraph text.
<div class="bd-example">
Nulla <abbr title="attribute">attr</abbr> vitae elit libero, a pharetra augue.
</div>
### Summary
The default `cursor` on summary is `text`, so we reset that to `pointer` to convey that the element can be interacted with by clicking on it.
<div class="bd-example">
<details>
<summary>Some details</summary>
<p>More info about the details.</p>
</details>
<details open>
<summary>Even more details</summary>
<p>Here are even more details about the details.</p>
</details>
</div>
## HTML5 `[hidden]` attribute
HTML5 adds [a new global attribute named `[hidden]`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden), which is styled as `display: none` by default. Borrowing an idea from [PureCSS](https://purecss.io/), we improve upon this default by making `[hidden] { display: none !important; }` to help prevent its `display` from getting accidentally overridden. While `[hidden]` isn't natively supported by IE10, the explicit declaration in our CSS gets around that problem.
{% highlight html %}
<input type="text" hidden>
{% endhighlight %}
{% callout warning %}
##### jQuery incompatibility
`[hidden]` is not compatible with jQuery's `$(...).hide()` and `$(...).show()` methods. Therefore, we don't currently especially endorse `[hidden]` over other techniques for managing the `display` of elements.
{% endcallout %}
To merely toggle the visibility of an element, meaning its `display` is not modified and the element can still affect the flow of the document, use [the `.invisible` class]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/visibility/) instead.

title: Tables
description: Documentation and examples for opt-in styling of tables (given their prevalent use in JavaScript plugins) with Bootstrap.
group: content
toc: true
---
## Examples
Due to the widespread use of tables across third-party widgets like calendars and date pickers, we've designed our tables to be **opt-in**. Just add the base class `.table` to any `<table>`, then extend with custom styles or our various included modifier classes.
Using the most basic table markup, here's how `.table`-based tables look in Bootstrap. **All table styles are inherited in Bootstrap 4**, meaning any nested tables will be styled in the same manner as the parent.
{% example html %}
<table class="table">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td>Larry</td>
<td>the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
You can also invert the colors—with light text on dark backgrounds—with `.table-dark`.
{% example html %}
<table class="table table-dark">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td>Larry</td>
<td>the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
## Table head options
Similar to tables and dark tables, use the modifier classes `.thead-light` or `.thead-dark` to make `<thead>`s appear light or dark gray.
{% example html %}
<table class="table">
<thead class="thead-dark">
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td>Larry</td>
<td>the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
<table class="table">
<thead class="thead-light">
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td>Larry</td>
<td>the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
## Striped rows
Use `.table-striped` to add zebra-striping to any table row within the `<tbody>`.
{% example html %}
<table class="table table-striped">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td>Larry</td>
<td>the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
{% example html %}
<table class="table table-striped table-dark">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td>Larry</td>
<td>the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
## Bordered table
Add `.table-bordered` for borders on all sides of the table and cells.
{% example html %}
<table class="table table-bordered">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td colspan="2">Larry the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
{% example html %}
<table class="table table-bordered table-dark">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td colspan="2">Larry the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
## Hoverable rows
Add `.table-hover` to enable a hover state on table rows within a `<tbody>`.
{% example html %}
<table class="table table-hover">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td colspan="2">Larry the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
{% example html %}
<table class="table table-hover table-dark">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td colspan="2">Larry the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
## Small table
Add `.table-sm` to make tables more compact by cutting cell padding in half.
{% example html %}
<table class="table table-sm">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td colspan="2">Larry the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
{% example html %}
<table class="table table-sm table-dark">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>

<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>

<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td colspan="2">Larry the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
## Contextual classes
Use contextual classes to color table rows or individual cells.
<div class="bd-example">
<table class="table">
<thead>
<tr>
<th scope="col">Class</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
</tr>
</thead>
<tbody>
<tr class="table-active">
<th scope="row">Active</th>
<td>Cell</td>
<td>Cell</td>
</tr>
<tr>

Regular table background variants are not available with the dark table, however, you may use [text or background utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/colors/) to achieve similar styles.

Create responsive tables by wrapping any `.table` with `.table-responsive{-sm|-md|-lg|-xl}`, making the table scroll horizontally at each `max-width` breakpoint of up to (but not including) 576px, 768px, 992px, and 1120px, respectively.
{% capture callout-include %}{% include callout-info-mediaqueries-breakpoints.md %}{% endcapture %}
{{ callout-include | markdownify }}
## Captions
A `<caption>` functions like a heading for a table. It helps users with screen readers to find a table and understand what it's about and decide if they want to read it.
{% example html %}
<table class="table">
<caption>List of users</caption>
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Handle</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Mark</td>
<td>Otto</td>
<td>@mdo</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Jacob</td>
<td>Thornton</td>
<td>@fat</td>
</tr>
<tr>
<th scope="row">3</th>
<td>Larry</td>
<td>the Bird</td>
<td>@twitter</td>
</tr>
</tbody>
</table>
{% endexample %}
## Responsive tables
Responsive tables allow tables to be scrolled horizontally with ease. Make any table responsive across all viewports by wrapping a `.table` with `.table-responsive`. Or, pick a maximum breakpoint with which to have a responsive table up to by using `.table-responsive{-sm|-md|-lg|-xl}`.
{% callout warning %}
##### Vertical clipping/truncation
Responsive tables make use of `overflow-y: hidden`, which clips off any content that goes beyond the bottom or top edges of the table. In particular, this can clip off dropdown menus and other third-party widgets.
{% endcallout %}
### Always responsive
Across every breakpoint, use `.table-responsive` for horizontally scrolling tables.
<div class="bd-example">
<div class="table-responsive">
<table class="table">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
<tr>
<th scope="row">3</th>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
</tbody>
</table>
</div>
</div>
{% highlight html %}
<div class="table-responsive">
<table class="table">
...
</table>
</div>
{% endhighlight %}
### Breakpoint specific
Use `.table-responsive{-sm|-md|-lg|-xl}` as needed to create responsive tables up to a particular breakpoint. From that breakpoint and up, the table will behave normally and not scroll horizontally.
<div class="bd-example">
{% for bp in site.data.breakpoints %}{% unless bp.breakpoint == "xs" %}
<div class="table-responsive{{ bp.abbr }}">
<table class="table">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
<th scope="col">Heading</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
<tr>
<th scope="row">2</th>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
<tr>
<th scope="row">3</th>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
</tbody>
</table>
</div>
{% endunless %}{% endfor %}
</div>
{% highlight html %}
{% for bp in site.data.breakpoints %}{% unless bp.breakpoint == "xs" %}
<div class="table-responsive{{ bp.abbr }}">
<table class="table">
...
</table>
</div>
{% endunless %}{% endfor %}
{% endhighlight %}

group: content
toc: true
---
## Global settings
Bootstrap sets basic global display, typography, and link styles. When more control is needed, check out the [textual utility classes]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/).
- Use a [native font stack]({{ site.baseurl }}/docs/{{ site.docs_version }}/content/reboot/#native-font-stack) that selects the best `font-family` for each OS and device.
- For a more inclusive and accessible type scale, we assume the browser default root `font-size` (typically 16px) so visitors can customize their browser defaults as needed.
- Use the `$font-family-base`, `$font-size-base`, and `$line-height-base` attributes as our typographic base applied to the `<body>`.
- Set the global link color via `$link-color` and apply link underlines only on `:hover`.
- Use `$body-bg` to set a `background-color` on the `<body>` (`#fff` by default).
These styles can be found within `_reboot.scss`, and the global variables are defined in `_variables.scss`. Make sure to set `$font-size-base` in `rem`.
## Headings
All HTML headings, `<h1>` through `<h6>`, are available.
<table>
<thead>
<tr>
<th>Heading</th>
<th>Example</th>
</tr>
</thead>
<tbody>
<tr>
<td>
{% markdown %}`<h1></h1>`{% endmarkdown %}
</td>
<td><span class="h1">h1. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h2></h2>`{% endmarkdown %}
</td>
<td><span class="h2">h2. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h3></h3>`{% endmarkdown %}
</td>
<td><span class="h3">h3. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h4></h4>`{% endmarkdown %}
</td>
<td><span class="h4">h4. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h5></h5>`{% endmarkdown %}
</td>
<td><span class="h5">h5. Bootstrap heading</span></td>
</tr>
<tr>
<td>
{% markdown %}`<h6></h6>`{% endmarkdown %}
</td>
<td><span class="h6">h6. Bootstrap heading</span></td>
</tr>
</tbody>
</table>
{% highlight html %}
<h1>h1. Bootstrap heading</h1>
<h2>h2. Bootstrap heading</h2>
<h3>h3. Bootstrap heading</h3>
<h4>h4. Bootstrap heading</h4>
<h5>h5. Bootstrap heading</h5>
<h6>h6. Bootstrap heading</h6>
{% endhighlight %}
`.h1` through `.h6` classes are also available, for when you want to match the font styling of a heading but cannot use the associated HTML element.
{% example html %}
<p class="h1">h1. Bootstrap heading</p>
<p class="h2">h2. Bootstrap heading</p>
<p class="h3">h3. Bootstrap heading</p>
<p class="h4">h4. Bootstrap heading</p>
<p class="h5">h5. Bootstrap heading</p>
<p class="h6">h6. Bootstrap heading</p>
{% endexample %}
### Customizing headings
Use the included utility classes to recreate the small secondary heading text from Bootstrap 3.
<div class="bd-example">
<span class="h3">
Fancy display heading
<small class="text-muted">With faded secondary text</small>
</span>
</div>
{% highlight html %}
<h3>
Fancy display heading
<small class="text-muted">With faded secondary text</small>
</h3>
{% endhighlight %}
## Display headings
Traditional heading elements are designed to work best in the meat of your page content. When you need a heading to stand out, consider using a **display heading**—a larger, slightly more opinionated heading style.
<div class="bd-example bd-example-type">
<table class="table">
<tbody>
<tr>
<td><span class="display-1">Display 1</span></td>
</tr>
<tr>
<td><span class="display-2">Display 2</span></td>
</tr>
<tr>
<td><span class="display-3">Display 3</span></td>
</tr>
<tr>
<td><span class="display-4">Display 4</span></td>
</tr>
</tbody>
</table>
</div>
{% highlight html %}
<h1 class="display-1">Display 1</h1>
<h1 class="display-2">Display 2</h1>
<h1 class="display-3">Display 3</h1>
<h1 class="display-4">Display 4</h1>
{% endhighlight %}
## Lead
Make a paragraph stand out by adding `.lead`.
{% example html %}
<p class="lead">
Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.
</p>
{% endexample %}
## Inline text elements
Styling for common inline HTML5 elements.
{% example html %}
<p>You can use the mark tag to <mark>highlight</mark> text.</p>
<p><del>This line of text is meant to be treated as deleted text.</del></p>
<p><s>This line of text is meant to be treated as no longer accurate.</s></p>
<p><ins>This line of text is meant to be treated as an addition to the document.</ins></p>
<p><u>This line of text will render as underlined</u></p>
<p><small>This line of text is meant to be treated as fine print.</small></p>
<p><strong>This line rendered as bold text.</strong></p>
<p><em>This line rendered as italicized text.</em></p>
{% endexample %}
`.mark` and `.small` classes are also available to apply the same styles as `<mark>` and `<small>` while avoiding any unwanted semantic implications that the tags would bring.
While not shown above, feel free to use `<b>` and `<i>` in HTML5. `<b>` is meant to highlight words or phrases without conveying additional importance while `<i>` is mostly for voice, technical terms, etc.
## Text utilities
Change text alignment, transform, style, weight, and color with our [text utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/text/) and [color utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/colors/).
## Abbreviations
Stylized implementation of HTML's `<abbr>` element for abbreviations and acronyms to show the expanded version on hover. Abbreviations have a default underline and gain a help cursor to provide additional context on hover and to users of assistive technologies.
Add `.initialism` to an abbreviation for a slightly smaller font-size.
{% example html %}
<p><abbr title="attribute">attr</abbr></p>
<p><abbr title="HyperText Markup Language" class="initialism">HTML</abbr></p>
{% endexample %}
## Blockquotes
For quoting blocks of content from another source within your document. Wrap `<blockquote class="blockquote">` around any <abbr title="HyperText Markup Language">HTML</abbr> as the quote.
{% example html %}
<blockquote class="blockquote">
<p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
</blockquote>
{% endexample %}
### Naming a source
Add a `<footer class="blockquote-footer">` for identifying the source. Wrap the name of the source work in `<cite>`.
{% example html %}
<blockquote class="blockquote">
<p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
<footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>
{% endexample %}
### Alignment
Use text utilities as needed to change the alignment of your blockquote.
{% example html %}
<blockquote class="blockquote text-center">
<p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
<footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>
{% endexample %}
{% example html %}
<blockquote class="blockquote text-right">
<p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
<footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>
{% endexample %}
## Lists
### Unstyled
Remove the default `list-style` and left margin on list items (immediate children only). **This only applies to immediate children list items**, meaning you will need to add the class for any nested lists as well.
{% example html %}
<ul class="list-unstyled">
<li>Lorem ipsum dolor sit amet</li>
<li>Consectetur adipiscing elit</li>
<li>Integer molestie lorem at massa</li>
<li>Facilisis in pretium nisl aliquet</li>
<li>Nulla volutpat aliquam velit
<ul>
<li>Phasellus iaculis neque</li>
<li>Purus sodales ultricies</li>
<li>Vestibulum laoreet porttitor sem</li>
<li>Ac tristique libero volutpat at</li>
</ul>
</li>
<li>Faucibus porta lacus fringilla vel</li>
<li>Aenean sit amet erat nunc</li>
<li>Eget porttitor lorem</li>
</ul>
{% endexample %}
### Inline
Remove a list's bullets and apply some light `margin` with a combination of two classes, `.list-inline` and `.list-inline-item`.
{% example html %}
<ul class="list-inline">
<li class="list-inline-item">Lorem ipsum</li>
<li class="list-inline-item">Phasellus iaculis</li>
<li class="list-inline-item">Nulla volutpat</li>
</ul>
{% endexample %}
### Description list alignment
Align terms and descriptions horizontally by using our grid system's predefined classes (or semantic mixins). For longer terms, you can optionally add a `.text-truncate` class to truncate the text with an ellipsis.
{% example html %}
<dl class="row">
<dt class="col-sm-3">Description lists</dt>
<dd class="col-sm-9">A description list is perfect for defining terms.</dd>
<dt class="col-sm-3">Euismod</dt>
<dd class="col-sm-9">
<p>Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.</p>
<p>Donec id elit non mi porta gravida at eget metus.</p>
</dd>
<dt class="col-sm-3">Malesuada porta</dt>
<dd class="col-sm-9">Etiam porta sem malesuada magna mollis euismod.</dd>
<dt class="col-sm-3 text-truncate">Truncated term is truncated</dt>
<dd class="col-sm-9">Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</dd>
<dt class="col-sm-3">Nesting</dt>
<dd class="col-sm-9">
<dl class="row">
<dt class="col-sm-4">Nested definition list</dt>
<dd class="col-sm-8">Aenean posuere, tortor sed cursus feugiat, nunc augue blandit nunc.</dd>
</dl>
</dd>
</dl>
{% endexample %}
## Responsive typography
*Responsive typography* refers to scaling text and components by simply adjusting the root element's `font-size` within a series of media queries. Bootstrap doesn't do this for you, but it's fairly easy to add if you need it.
Here's an example of it in practice. Choose whatever `font-size`s and media queries you wish.
{% highlight scss %}
html {
font-size: 1rem;
}
@include media-breakpoint-up(sm) {
html {
font-size: 1.2rem;
}
}
@include media-breakpoint-up(md) {
html {
font-size: 1.4rem;
}
}
@include media-breakpoint-up(lg) {
html {
font-size: 1.6rem;
}
}
{% endhighlight %}

<h1>Bootstrap grid examples</h1>
<p class="lead">Basic grid layouts to get you familiar with building within the Bootstrap grid system.</p>
<h3>Five grid tiers</h3>
<p>There are five tiers to the Bootstrap grid system, one for each range of devices we support. Each tier starts at a minimum viewport size and automatically applies to the larger devices unless overridden.</p>
<div class="row">
<div class="col-4">.col-4</div>
<div class="col-4">.col-4</div>
<div class="col-4">.col-4</div>
</div>
<div class="row">
<div class="col-sm-4">.col-sm-4</div>
<div class="col-sm-4">.col-sm-4</div>
<div class="col-sm-4">.col-sm-4</div>
</div>
<div class="row">
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
</div>
<div class="row">
<div class="col-lg-4">.col-lg-4</div>
<div class="col-lg-4">.col-lg-4</div>
<div class="col-lg-4">.col-lg-4</div>
</div>
<div class="row">
<div class="col-xl-4">.col-xl-4</div>
<div class="col-xl-4">.col-xl-4</div>
<div class="col-xl-4">.col-xl-4</div>
</div>
<h3>Three equal columns</h3>
<p>Get three equal-width columns <strong>starting at desktops and scaling to large desktops</strong>. On mobile devices, tablets and below, the columns will automatically stack.</p>
<div class="row">
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
</div>
<h3>Three unequal columns</h3>
<p>Get three columns <strong>starting at desktops and scaling to large desktops</strong> of various widths. Remember, grid columns should add up to twelve for a single horizontal block. More than that, and columns start stacking no matter the viewport.</p>
<div class="row">
<div class="col-md-3">.col-md-3</div>
<div class="col-md-6">.col-md-6</div>
<div class="col-md-3">.col-md-3</div>
</div>
<h3>Two columns</h3>
<p>Get two columns <strong>starting at desktops and scaling to large desktops</strong>.</p>
<div class="row">
<div class="col-md-8">.col-md-8</div>
<div class="col-md-4">.col-md-4</div>
</div>
<h3>Full width, single column</h3>
<p class="text-warning">No grid classes are necessary for full-width elements.</p>
<hr>
<h3>Two columns with two nested columns</h3>
<p>Per the documentation, nesting is easy—just put a row of columns within an existing column. This gives you two columns <strong>starting at desktops and scaling to large desktops</strong>, with another two (equal widths) within the larger column.</p>
<p>At mobile device sizes, tablets and down, these columns and their nested columns will stack.</p>
<div class="row">
<div class="col-md-8">
.col-md-8
<div class="row">
<div class="col-md-6">.col-md-6</div>
<div class="col-md-6">.col-md-6</div>
</div>
</div>
<div class="col-md-4">.col-md-4</div>
</div>
<hr>
<h3>Mixed: mobile and desktop</h3>
<p>The Bootstrap v4 grid system has five tiers of classes: xs (extra small), sm (small), md (medium), lg (large), and xl (extra large). You can use nearly any combination of these classes to create more dynamic and flexible layouts.</p>
<p>Each tier of classes scales up, meaning if you plan on setting the same widths for xs and sm, you only need to specify xs.</p>
<div class="row">
<div class="col-12 col-md-8">.col-12 .col-md-8</div>
<div class="col-6 col-md-4">.col-6 .col-md-4</div>
</div>
<div class="row">
<div class="col-6 col-md-4">.col-6 .col-md-4</div>
<div class="col-6 col-md-4">.col-6 .col-md-4</div>
<div class="col-6 col-md-4">.col-6 .col-md-4</div>
</div>
<div class="row">
<div class="col-6">.col-6</div>
<div class="col-6">.col-6</div>

<h3>Mixed: mobile, tablet, and desktop</h3>

<h1>Navbar examples</h1>
<p>This example is a quick exercise to illustrate how the navbar and its contents work. Some navbars extend the width of the viewport, others are confined within a <code>.container</code>. For positioning of navbars, checkout the <a href="../navbar-top/">top</a> and <a href="../navbar-top-fixed/">fixed top</a> examples.</p>
<p>At the smallest breakpoint, the collapse plugin is used to hide the links and show a menu button to toggle the collapsed content.</p>

title: Approach
description: Learn about the guiding principles, strategies, and techniques used to build and maintain Bootstrap so you can more easily customize and extend it yourself.
group: extend
---
While the getting started pages provide an introductory tour of the project and what it offers, this document focuses on _why_ we do the things we do in Bootstrap. It explains our philosophy to building on the web so that others can learn from us, contribute with us, and help us improve.
See something that doesn't sound right, or perhaps could be done better? [Open an issue](https://github.com/twbs/bootstrap/issues/new)—we'd love to discuss it with you.
## Summary
We'll dive into each of these more throughout, but at a high level, here's what guides our approach.
- Components should be responsive and mobile-first
- Components should be built with a base class and extended via modifier classes
- Component states should obey a common z-index scale
- Whenever possible, prefer a HTML and CSS implementation over JavaScript
- Whenever possible, use utilities over custom styles
- Whenever possible, avoid enforcing strict HTML requirements (children selectors)
## Responsive
Bootstrap's responsive styles are built to be responsive, an approach that's often referred to as _mobile-first_. We use this term in our docs and largely agree with it, but at times it can be too broad. While not every component _must_ be entirely responsive in Bootstrap, this responsive approach is about reducing CSS overrides by pushing you to add styles as the viewport becomes larger.
Across Bootstrap, you'll see this most clearly in our media queries. In most cases, we use `min-width` queries that begin to apply at a specific breakpoint and carry up through the higher breakpoints. For example, a `.d-none` applies from `min-width: 0` to infinity. On the other hand, a `.d-md-none` applies from the medium breakpoint and up.
At times we'll use `max-width` when a component's inherent complexity requires it. At times, these overrides are functionally and mentally clearer to implement and support than rewriting core functionality from our components. We strive to limit this approach, but will use it from time to time.
## Classes
Aside from our Reboot, a cross-browser normalization stylesheet, all our styles aim to use classes as selectors. This means steering clear of type selectors (e.g., `input[type="text"]`) and extraneous parent classes (e.g., `.parent .child`) that make styles too specific to easily override.
As such, components should be built with a base class that houses common, not-to-be overridden property-value pairs. For example, `.btn` and `.btn-primary`. We use `.btn` for all the common styles like `display`, `padding`, and `border-width`. We then use modifiers like `.btn-primary` to add the color, background-color, border-color, etc.
Modifier classes should only be used when there are multiple properties or values to be changed across multiple variants. Modifiers are not always necessary, so be sure you're actually saving lines of code and preventing unnecessary overrides when creating them. Good examples of modifiers are our theme color classes and size variants.
## z-index scales
There are two `z-index` scales in Bootstrap—elements within a component and overlay components.
### Component elements
- Some components in Bootstrap are built with overlapping elements to prevent double borders without modifying the `border` property. For example, button groups, input groups, and pagination.
- These components share a standard `z-index` scale of `0` through `3`.
- `0` is default (initial), `1` is `:hover`, `2` is `:active`/`.active`, and , `3` is `:focus`.
- This approach matches our expectations of highest user priority. If an element is focused, it's in view and at the user's attention. Active elements are second highest because they indicate state. Hover is third highest because it indicates user intent, but nearly _anything_ can be hovered.
### Overlay components
Bootstrap includes several components that function as an overlay of some kind. This includes, in order of highest `z-index`, dropdowns, fixed and sticky navbars, modals, tooltips, and popovers. These components have their own `z-index` scale that begins at `1000`. This starting number is random and serves as a small buffer between our styles and your project's custom styles.
Each overlay component increases it's `z-index` value slightly in such a way that common UI principles allow user focused or hovered elements to remain in view at all times. For example, a modal is document blocking (e.g., you cannot take any other action save for the modal's action), so we put that above our navbars.
Learn more about this in our [`z-index` layout page](/docs/4.0/layout/overview/#z-index).
## HTML and CSS over JS
Whenever possible, we prefer to write HTML and CSS over JavaScript. In general, HTML and CSS are more prolific and accessible to more people of all different experience levels. HTML and CSS are also faster in your browser than JavaScript, and your browser general provides a great deal of functionality for you.
This principle is our first-class JavaScript API is `data` attributes. You dont need to write nearly any JavaScript to use our JavaScript plugins; instead, write HTML. Read more about this in [our JavaScript overview page]().
Lastly, our styles build on the fundamental behaviors of common web elements. Whenever possible, we prefer to use what the browser provides. For example, you can put a `.btn` class on nearly any element, but most elements dont provide any semantic value or browser functionality. So instead, we use `<button>`s and `<a>`s.
The same goes for more complex components. While we *could* write our own form validation plugin to add classes to a parent element based on an inputs state, thereby allowing us to style the text say red, we prefer using the `:valid`/`:invalid` pseudo-elements every browser provides us.
## Utilities
Utility classes—formerly helpers in Bootstrap 3—are a powerful ally in combatting CSS bloat and poor page performance. A utility class is typically a single, immutable property-value pairing expressed as a class (e.g., `.d-block` represents `display: block;`). Their primary appeal is speed of use while writing HTML and limiting the amount of custom CSS you have to write.
Specifically regarding custom CSS, utilities can help combat increasing file size by reducing your most commonly repeated property-value pairs into single classes. This can have a dramatic effect at scale in your projects.
## Flexible HTML
While not always possible, we strive to avoid being overly dogmatic in our HTML requirements for components. Thus, we focus on single classes in our CSS selectors and try to avoid immediate children selectors (`~`). This gives you more flexibility in your implementation and helps keep our CSS simpler and less specific.

title: Icons
description: Guidance and suggestions for using external icon libraries with Bootstrap.
group: extend
---
Bootstrap doesn't include an icon library by default, but we have a handful of recommendations for you to choose from. While most icon sets include multiple file formats, we prefer SVG implementations for their improved accessibility and vector support.
## Preferred
We've tested and used these icon sets ourselves.
- [Iconic](https://useiconic.com/open/)
- [Octicons](https://octicons.github.com/)
## More options
While we haven't tried these out, they do look promising and provide multiple formats—including SVG.
- [Bytesize](https://github.com/danklammer/bytesize-icons)
- [Google Material icons](https://material.io/icons/)
- [Ionicons](http://ionicons.com/)
- [Feather](https://feathericons.com/)
- [Dripicons](http://demo.amitjakhu.com/dripicons/)
- [Ikons](http://ikons.piotrkwiatkowski.co.uk/)
- [Glyph](http://glyph.smarticons.co/)
