Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.
## Contents
* Will be replaced with the ToC, excluding the "Contents" header

**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').focus()
})
{% endhighlight %}
{% callout warning %}
#### Multiple open modals not supported
Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.
{% endcallout %}
{% callout warning %}
#### Modal markup placement
Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality.
{% endcallout %}
{% callout warning %}
#### Mobile device caveats
There are some caveats regarding using modals on mobile devices. [See our browser support docs]({{ site.baseurl }}/getting-started/browsers-devices/#modals-navbars-and-virtual-keyboards) for details.

### Static example
A rendered modal with header, body, and set of actions in the footer.
<p>Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>
<h4>Popover in a modal</h4>
<p>This <ahref="#"role="button"class="btn btn-secondary popover-test"title="A Title"data-content="And here's some amazing content. It's very engaging. right?">button</a> should trigger a popover on click.</p>
<h4>Tooltips in a modal</h4>
<p><ahref="#"class="tooltip-test"title="Tooltip">This link</a> and <ahref="#"class="tooltip-test"title="Tooltip">that link</a> should have tooltips on hover.</p>
<hr>
<h4>Overflowing text to show scroll behavior</h4>
<p>Cras mattis consectetur purus sit amet fermentum. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Morbi leo risus, porta ac consectetur ac, vestibulum at eros.</p>
<p>Praesent commodo cursus magna, vel scelerisque nisl consectetur et. Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor.</p>
<p>Aenean lacinia bibendum nulla sed consectetur. Praesent commodo cursus magna, vel scelerisque nisl consectetur et. Donec sed odio dui. Donec ullamcorper nulla non metus auctor fringilla.</p>

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.
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.
To take advantage of the Bootstrap grid system within a modal, just nest `.container-fluid` within the `.modal-body` and then use the normal grid system classes within this container.
Have a bunch of buttons that all trigger the same modal, just with slightly different contents? Use `event.relatedTarget` and [HTML `data-*` attributes](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes) (possibly [via jQuery](https://api.jquery.com/data/)) to vary the contents of the modal depending on which button was clicked. See the Modal Events docs for details on `relatedTarget`.
{% example html %}
<divclass="bd-example">
<buttontype="button"class="btn btn-primary"data-toggle="modal"data-target="#exampleModal"data-whatever="@mdo">Open modal for @mdo</button>
<buttontype="button"class="btn btn-primary"data-toggle="modal"data-target="#exampleModal"data-whatever="@fat">Open modal for @fat</button>
<buttontype="button"class="btn btn-primary"data-toggle="modal"data-target="#exampleModal"data-whatever="@getbootstrap">Open modal for @getbootstrap</button>
$('#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 = $(this)
modal.find('.modal-title').text('New message to ' + recipient)
modal.find('.modal-body input').val(recipient)
})
{% endhighlight %}
## Modals with dynamic heights
If the height of a modal changes while it is open, you should call `$('#myModal').data('bs.modal').handleUpdate()` to readjust the modal's position in case a scrollbar appears.
## 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.
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-backdrop=""`.
<divclass="table-responsive">
<tableclass="table table-bordered table-striped">
<thead>
<tr>
<thstyle="width: 100px;">Name</th>
<thstyle="width: 50px;">Type</th>
<thstyle="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>

<td>Closes the modal when escape key is pressed</td>

<td>Shows the modal when initialized.</td>

</div>
### Methods
#### `.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).
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">`).
<divclass="table-responsive">
<tableclass="table table-bordered table-striped">
<thead>
<tr>
<thstyle="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>
<tr>
<td>loaded.bs.modal</td>
<td>This event is fired when the modal has loaded content using the <code>remote</code> option.</td>
</tr>
</tbody>
</table>
</div>
{% highlight js %}
$('#myModal').on('hidden.bs.modal', function (e) {
