## 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 %}
{% include callout-info-prefersreducedmotion.md %}
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">
<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">×</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>
<div class="modal-body">

<button type="button" class="btn btn-primary">Save changes</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 class="modal fade" id="exampleModalLive" tabindex="-1" role="dialog" aria-labelledby="exampleModalLiveLabel" aria-hidden="true">
<div class="modal-dialog">
<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">×</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">

<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog">

<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
{% endhighlight %}
### Static backdrop
When backdrop is set to static, the modal will not close when clicking outside it. Click the button below to try it.
<div class="modal fade" id="staticBackdropLive" data-backdrop="static" data-keyboard="false" tabindex="-1" role="dialog" aria-labelledby="staticBackdropLiveLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="staticBackdropLiveLabel">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>I will not close if you click outside me. Don't even try to press escape key.</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">Understood</button>
</div>
</div>
</div>
</div>
<div class="bd-example">
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#staticBackdropLive">

</button>
</div>
{% highlight html %}
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#staticBackdrop">

</button>
<!-- Modal -->
<div class="modal fade" id="staticBackdrop" data-backdrop="static" data-keyboard="false" tabindex="-1" role="dialog" aria-labelledby="staticBackdropLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="staticBackdropLabel">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">

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

</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Understood</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 class="modal fade" id="exampleModalLong" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
<div class="modal-dialog">
<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">×</span>
</button>
</div>
<div class="modal-body">

<div class="bd-example">
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalLong">

</div>
You can also create a scrollable modal that allows scroll the modal body by adding `.modal-dialog-scrollable` to `.modal-dialog`.
<div class="modal fade" id="exampleModalScrollable" tabindex="-1" role="dialog" aria-labelledby="exampleModalScrollableTitle" aria-hidden="true">
<div class="modal-dialog modal-dialog-scrollable">
<div class="modal-content">
<div class="modal-header">

<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<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>

### 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.

### 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`.
{% capture example %}
<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">

// Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
var modal = $(this)
modal.find('.modal-title').text('New message to ' + recipient)
modal.find('.modal-body input').val(recipient)
})
{% endhighlight %}
### Change animation
The `$modal-fade-transform` variable determines the transform state of `.modal-dialog` before the modal fade-in animation, the `$modal-show-transform` variable determines the transform of `.modal-dialog` at the end of the modal fade-in animation.
If you want for example a zoom-in animation, you can set `$modal-fade-transform: scale(.8)`.
### 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`. 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 three 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.
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>Size</th>
<th>Class</th>
<th>Modal max-width</th>
</tr>
</thead>
<tbody>
<tr>
<td>Small</td>
<td><code>.modal-sm</code></td>
<td><code>300px</code></td>
</tr>
<tr>
<td>Default</td>
<td class="text-muted">None</td>
<td><code>500px</code></td>
</tr>
<tr>
<td>Large</td>
<td><code>.modal-lg</code></td>
<td><code>800px</code></td>
</tr>
<tr>
<td>Extra large</td>
<td><code>.modal-xl</code></td>
<td><code>1140px</code></td>
</tr>
</tbody>
</table>
Our default modal without modifier class constitutes the "medium" size modal.
<div class="bd-example">
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalXl">Extra large modal</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalLg">Large modal</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalSm">Small modal</button>
</div>
{% highlight html %}
<div class="modal-dialog modal-xl">...</div>
<div class="modal-dialog modal-lg">...</div>
<div class="modal-dialog modal-sm">...</div>
{% endhighlight %}

## 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
{% include callout-danger-async-methods.md %}
#### `.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>
<tr>
<td>hidePrevented.bs.modal</td>
<td>This event is fired when the modal is shown, its backdrop is <code>static</code> and a click outside the modal or an escape key press is performed with the keyboard option or <code>data-keyboard</code> set to <code>false</code>.</td>
</tr>
</tbody>
</table>
{% highlight js %}
$('#myModal').on('hidden.bs.modal', function (e) {
// do something...
})
{% endhighlight %}
