+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 %}
+
+{% 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.
+

+### 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.

+### 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">
+ <div class="modal-dialog">
+ <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>
+{% endcapture %}
+{% include example.html content=example %}
+
+{% 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 = $(this)
+ modal.find('.modal-title').text('New message to ' + recipient)
+ modal.find('.modal-body input').val(recipient)
+})
+{% endhighlight %}
+
+### Change animation
+
+The `$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.

+
+## 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>
+

+
+{% 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).

+
+#### `.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 %}
