Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.
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.
There are some caveats regarding using modals on mobile devices. See our browser support docs for details.
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:
A rendered modal with header, body, and set of actions in the footer.
Toggle a modal via JavaScript by clicking the button below. It will slide down and fade in from the top of the page.
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 in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. See this helpful Stack Overflow post for more information.
Modals have two optional sizes, available via modifier classes to be placed on a .modal-dialog
.
For modals that simply appear rather than fade in to view, remove the .fade
class from your modal markup.
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.
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
,
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.
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.
Call a modal with id myModal
with a single line of JavaScript:
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. |
remote | path | false |
This option is deprecated since v3.3.0 and will be removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself. If a remote URL is provided, content will be loaded one time via jQuery's |
.modal(options)
Activates your content as a modal. Accepts an optional options object
.
.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).
.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).
.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).
.modal('handleUpdate')
Readjusts the modal's positioning to counter a scrollbar in case one should appear, which would make the modal jump to the left.
Only needed when the height of the modal changes while it is open.
{% highlight js %}$('#myModal').modal('handleUpdate'){% endhighlight %}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. |
