Components

Over a dozen reusable components built to provide buttons, dropdowns, input groups, navigation, alerts, and much more.

Modal

Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.

Contents

Due to how HTML5 defines its semantics, the autofocus HTML attribute has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript:

$('#myModal').on('shown.bs.modal', function () {
  $('#myInput').focus()
})

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.

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.

Mobile device caveats

There are some caveats regarding using modals on mobile devices. See our browser support docs for details.

Static example

A rendered modal with header, body, and set of actions in the footer.

Modal title

One fine body…

<div class="modal fade">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>One fine body&hellip;</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><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

Live demo

Toggle a modal via JavaScript by clicking the button below. It will slide down and fade in from the top of the page.

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </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>

Make modals accessible

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 for more information.

Optional sizes

Modals have two optional sizes, available via modifier classes to be placed on a .modal-dialog.

<!-- Large modal -->
<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>

Remove animation

For modals that simply appear rather than fade in to view, remove the .fade class from your modal markup.

<div class="modal" tabindex="-1" role="dialog" aria-labelledby="..." aria-hidden="true">
  ...
</div>

Using the grid system

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.

<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">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="gridModalLabel">Modal title</h4>
      </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 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
          </div>
          <div class="row">
            <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
            <div class="col-md-2 col-md-offset-4">.col-md-2 .col-md-offset-4</div>
          </div>
          <div class="row">
            <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
          </div>
          <div class="row">
            <div class="col-sm-9">
              Level 1: .col-sm-9
              <div class="row">
                <div class="col-xs-8 col-sm-6">
                  Level 2: .col-xs-8 .col-sm-6
                </div>
                <div class="col-xs-4 col-sm-6">
                  Level 2: .col-xs-4 .col-sm-6
                </div>
              </div>
            </div>
          </div>
        </div>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
<div class="bd-example bd-example-padded-bottom">
  <button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#gridSystemModal">
    Launch demo modal
  </button>
</div>

Varying modal content based on trigger button

Have a bunch of buttons that all trigger the same modal, just with slightly different contents? Use event.relatedTarget and HTML data-* attributes (possibly via jQuery) to vary the contents of the modal depending on which button was clicked. See the Modal Events docs for details on relatedTarget.

<div class="bd-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">
          <button type="button" class="close" data-dismiss="modal" aria-label="Close">
            <span aria-hidden="true">&times;</span>
          </button>
          <h4 class="modal-title" id="exampleModalLabel">New message</h4>
        </div>
        <div class="modal-body">
          <form>
            <div class="form-group">
              <label for="recipient-name" class="form-control-label">Recipient:</label>
              <input type="text" class="form-control" id="recipient-name">
            </div>
            <div class="form-group">
              <label for="message-text" class="form-control-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>
</div>
$('#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)
})

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.

<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>

Via JavaScript

Call a modal with id myModal with a single line of JavaScript:

$('#myModal').modal(options)

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-backdrop="".

Name Type Default Description
backdrop boolean or the string 'static' true Includes a modal-backdrop element. Alternatively, specify static for a backdrop which doesn't close the modal on click.
keyboard boolean true Closes the modal when escape key is pressed
show boolean true Shows the modal when initialized.

Methods

.modal(options)

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

$('#myModal').modal({
  keyboard: false
})

.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).

$('#myModal').modal('toggle')

.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).

$('#myModal').modal('show')

.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).

$('#myModal').modal('hide')

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">).

Event Type Description
show.bs.modal This event fires immediately when the show instance method is called. If caused by a click, the clicked element is available as the relatedTarget property of the event.
shown.bs.modal 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 relatedTarget property of the event.
hide.bs.modal This event is fired immediately when the hide instance method has been called.
hidden.bs.modal This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
loaded.bs.modal This event is fired when the modal has loaded content using the remote option. 
$('#myModal').on('hidden.bs.modal', function (e) {
  // do something...
})
