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 {:toc}

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:

{% 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-and-dropdowns-on-mobile) for details. {% endcallout %}

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.

  <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">
    <h4>Text in a modal</h4>
    <p>Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>

    <h4>Popover in a modal</h4>
    <p>This <a href="#" 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><a href="#" class="tooltip-test" title="Tooltip">This link</a> and <a href="#" class="tooltip-test" title="Tooltip">that link</a> should have tooltips on hover.</p>

    <hr>

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. {% endcallout %}

{% callout info %}

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. {% endcallout %}

Optional sizes

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.

Remove animation

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

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.

{% example html %}

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.

{% example html %}

Open modal for @mdo Open modal for @fat Open modal for @getbootstrap

{% 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 %}

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.

{% highlight html %} Launch modal {% 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="".

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.

{% 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 %}

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.

{% highlight js %} $('#myModal').on('hidden.bs.modal', function (e) { // do something... }) {% endhighlight %}
