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 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:
$(’#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.

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.
Modal title
Modal body text goes here.
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.
Launch demo modalStatic backdrop
When backdrop is set to static, the modal will not close when clicking outside it. Click the button below to try it.
Launch static backdrop modalScrolling 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.
Launch demo modalYou can also create a scrollable modal that allows scroll the modal body by adding .modal-dialog-scrollable to .modal-dialog.
Launch demo modalVertically centered
Add .modal-dialog-centered to .modal-dialog to vertically center the modal.
Launch demo modalTooltips and popovers
Tooltips and popovers can be placed within modals as needed. When modals are closed, any tooltips and popovers within are also automatically dismissed.
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.
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 (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.
Open modal for @mdo
Open modal for @fat
Open modal for @getbootstrap
$(’#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)
})
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.
Dynamic heights
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.
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 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.
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.
Extra large modal

Usage
The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds .modal-open to the 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.
Launch modal
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 or on escape key press.
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.
Methods
Asynchronous methods and transitions
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.
See our JavaScript documentation for more information.
.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.
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
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).
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.
$(’#myModal’).on(‘hidden.bs.modal’, function (e) {
// do something…
})
