Use Bootstrap’s JavaScript modal plugin to add dialogs to your site for lightboxes, user notifications, or completely custom content.
Before getting started with Bootstrap’s modal component, be sure to read the following as our menu options have recently changed.
<body>
so that modal content scrolls instead.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.position: fixed
, there are some caveats with using modals on mobile devices. See our browser support docs for details.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').trigger('focus') })
The animation effect of this component is dependent on the prefers-reduced-motion
media query. See the reduced motion section of our accessibility documentation.
Keep reading for demos and usage guidelines.
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="modal" tabindex="-1"> <div class="modal-dialog"> <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">×</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>
Toggle a working modal demo 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" data-toggle="modal" data-target="#exampleModal"> Launch demo modal </button> <!-- Modal --> <div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog"> <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">×</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>
When backdrop is set to static, the modal will not close when clicking outside it. Click the button below to try it.
<!-- Button trigger modal --> <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#staticBackdrop"> Launch static backdrop modal </button> <!-- Modal --> <div class="modal fade" id="staticBackdrop" data-backdrop="static" data-keyboard="false" tabindex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="staticBackdropLabel">Modal title</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</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">Understood</button> </div> </div> </div> </div>
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.
Open example on getbootstrap.com
You can also create a scrollable modal that allows scroll the modal body by adding .modal-dialog-scrollable
to .modal-dialog
.
<!-- Scrollable modal --> <div class="modal-dialog modal-dialog-scrollable"> ... </div>
Add .modal-dialog-centered
to .modal-dialog
to vertically center the modal.
<!-- Vertically centered modal --> <div class="modal-dialog modal-dialog-centered"> ... </div> <!-- Vertically centered scrollable modal --> <div class="modal-dialog modal-dialog-centered modal-dialog-scrollable"> ... </div>
Tooltips and popovers can be placed within modals as needed. When modals are closed, any tooltips and popovers within are also automatically dismissed.
<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>
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 class="modal-body"> <div class="container-fluid"> <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> <div class="row"> <div class="col-md-3 ml-auto">.col-md-3 .ml-auto</div> <div class="col-md-2 ml-auto">.col-md-2 .ml-auto</div> </div> <div class="row"> <div class="col-md-6 ml-auto">.col-md-6 .ml-auto</div> </div> <div class="row"> <div class="col-sm-9"> Level 1: .col-sm-9 <div class="row"> <div class="col-8 col-sm-6"> Level 2: .col-8 .col-sm-6 </div> <div class="col-4 col-sm-6"> Level 2: .col-4 .col-sm-6 </div> </div> </div> </div> </div> </div>
Have a bunch of buttons that all trigger the same modal 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.
Below is a live demo followed by example HTML and JavaScript. For more information, read the modal events docs for details on relatedTarget
.
<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" 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">×</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>
$('#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) })
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)
.
For modals that simply appear rather than fade in to view, remove the .fade
class from your modal markup.
<div class="modal" tabindex="-1" aria-labelledby="..." aria-hidden="true"> ... </div>
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.
Be sure to add aria-labelledby="..."
, referencing the modal title, to .modal
. Additionally, you may give a description of your modal dialog with aria-describedby
on .modal
. Note that you don’t need to add role="dialog"
since we already add it via JavaScript.
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 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.
Size | Class | Modal max-width |
---|---|---|
Small | .modal-sm | 300px |
Default | None | 500px |
Large | .modal-lg | 800px |
Extra large | .modal-xl | 1140px |
Our default modal without modifier class constitutes the “medium” size modal.
<div class="modal-dialog modal-xl">...</div> <div class="modal-dialog modal-lg">...</div> <div class="modal-dialog modal-sm">...</div>
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.
<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
Call a modal with id myModal
with a single line of JavaScript:
$('#myModal').modal(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 |
focus | boolean | true | Puts the focus on the modal when initialized. |
show | boolean | true | Shows the modal when initialized. |
All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.
.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')
.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).
$('#myModal').modal('handleUpdate')
.modal('dispose')
Destroys an element’s modal.
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. |
hidePrevented.bs.modal | This event is fired when the modal is shown, its backdrop is static and a click outside the modal or an escape key press is performed with the keyboard option or data-keyboard set to false . |
$('#myModal').on('hidden.bs.modal', function (e) { // do something... })
