## 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]({{< docsref "/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 >}}
var myModal = document.getElementById('myModal')
var myInput = document.getElementById('myInput')

myModal.addEventListener('shown.bs.modal', function () {
  myInput.focus()
})
{{< /highlight >}}

{{< callout info >}}
{{< partial "callout-info-prefersreducedmotion.md" >}}
{{< /callout >}}

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">
          <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>

### 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-secondary" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
{{< /highlight >}}

### 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">
        <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>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>
        <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>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>
      </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="#exampleModalLong">
    Launch demo modal
  </button>
</div>

{{< highlight html >}}
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalLong">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="exampleModalLong" 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">

      <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">Save changes</button>
      </div>
    </div>
  </div>
</div>
{{< /highlight >}}

You can also create a scrollable modal that allows scroll the modal body by adding `.modal-dialog-scrollable` to `.modal-dialog`.

<div id="exampleModalScrollable" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="exampleModalScrollableTitle" aria-hidden="true">
  <div class="modal-dialog modal-dialog-scrollable" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalScrollableTitle">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>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>
        <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]({{< docsref "/components/tooltips" >}}) and [popovers]({{< docsref "/components/popovers" >}}) can be placed within modals as needed. When modals are closed, any tooltips and popovers within are also automatically dismissed.

<div id="exampleModalPopovers" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="exampleModalPopoversLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalPopoversLabel">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">
        <h5>Popover in a modal</h5>

        <h5>Tooltips in a modal</h5>
        <p><a href="#" class="tooltip-test" title="Tooltip" data-container="#exampleModalPopovers">This link</a> and <a href="#" class="tooltip-test" title="Tooltip" data-container="#exampleModalPopovers">that link</a> have tooltips on hover.</p>

</div>

{{< highlight html >}}
<div class="modal-body">
  <h5>Popover in a modal</h5>
  <p>This <a href="#" role="button" class="btn btn-secondary popover-test" title="Popover title" data-content="Popover body content is set in this attribute.">button</a> triggers a popover on click.</p>
  <hr>
  <h5>Tooltips in a modal</h5>
  <p><a href="#" class="tooltip-test" title="Tooltip">This link</a> and <a href="#" class="tooltip-test" title="Tooltip">that link</a> have tooltips on hover.</p>
</div>

### 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">
          <div class="row">
            <div class="col-md-4">.col-md-4</div>
            <div class="col-md-4 ml-auto">.col-md-4 .ml-auto</div>

          <div class="row">
            <div class="col-md-6 ml-auto">.col-md-6 .ml-auto</div>

### 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) 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 >}}
<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>
{{< /example >}}

{{< highlight js >}}
var exampleModal = document.getElementById('exampleModal')
exampleModal.addEventListener('show.bs.modal', function (event) {
  // Button that triggered the modal
  var button = event.relatedTarget
  // Extract info from data-* attributes
  var recipient = button.getAttribute('data-whatever')
  // If necessary, you could initiate an AJAX request here
  // and then do the updating in a callback.
  //
  // Update the modal's content.
  exampleModal.querySelector('.modal-title').textContent = 'New message to ' + recipient
  exampleModal.querySelector('.modal-body input').value = recipient
})
{{< /highlight >}}

### 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>
{{< /highlight >}}

### Dynamic heights

If the height of a modal changes while it is open, you should call `myModal.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 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.

  <button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bd-example-modal-xl">Extra large modal</button>

## 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>
{{< /highlight >}}

### Via JavaScript

Create a modal with a single line of JavaScript:

{{< highlight js >}}var myModal = new bootstrap.Modal(document.getElementById('myModal'), options){{< /highlight >}}

### 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

{{< callout danger >}}
{{< partial "callout-danger-async-methods.md" >}}
{{< /callout >}}

#### Passing options

Activates your content as a modal. Accepts an optional options `object`.

{{< highlight js >}}
var myModal = new bootstrap.Modal(document.getElementById('myModal'), {
  keyboard: false
})
{{< /highlight >}}

#### 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.toggle(){{< /highlight >}}

#### 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.show(){{< /highlight >}}

#### 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.hide(){{< /highlight >}}

#### 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.handleUpdate(){{< /highlight >}}

#### dispose

Destroys an element's modal.

{{< highlight js >}}myModal.dispose(){{< /highlight >}}

#### _getInstance

*Static* method which allows you to get the modal instance associated with a DOM element

{{< highlight js >}}
var myModalEl = document.getElementById('myModal')
var modal = bootstrap.Modal._getInstance(myModalEl) // Return a Bootstrap modal instance
{{< /highlight >}}

### 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 >}}
var myModalEl = document.getElementById('myModal')
myModalEl.addEventListener('hidden.bs.modal', function (e) {
  // do something...
})
{{< /highlight >}}
