Use Bootstrap’s JavaScript modal plugin to add dialogs to your site for lightboxes, user notifications, or completely custom content.
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="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
<p>Modal body text goes here.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-bs-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-bs-toggle="modal" data-bs-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="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-bs-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-bs-toggle="modal" data-bs-target="#staticBackdrop">
Launch static backdrop modal
</button>
<!-- Modal -->
<div class="modal fade" id="staticBackdrop" data-bs-backdrop="static" data-bs-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="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-bs-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.
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-bs-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 ms-auto">.col-md-4 .ms-auto</div>
</div>
<div class="row">
<div class="col-md-3 ms-auto">.col-md-3 .ms-auto</div>
<div class="col-md-2 ms-auto">.col-md-2 .ms-auto</div>
</div>
<div class="row">
<div class="col-md-6 ms-auto">.col-md-6 .ms-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-bs-* attributes 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-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@mdo">Open modal for @mdo</button>
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@fat">Open modal for @fat</button>
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-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="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
<form>
<div class="mb-3">
<label for="recipient-name" class="col-form-label">Recipient:</label>
<input type="text" class="form-control" id="recipient-name">
</div>
<div class="mb-3">
<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-danger" data-bs-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Send message</button>
</div>
</div>
</div>
</div>var exampleModal = document.getElementById('exampleModal')
exampleModal.addEventListener('show.bs.modal', function (event) {
// Button that triggered the modal
var button = event.relatedTarget
// Extract info from data-bs-* attributes
var recipient = button.getAttribute('data-bs-whatever')
// If necessary, you could initiate an AJAX request here
// and then do the updating in a callback.
//
// Update the modal's content.
var modalTitle = exampleModal.querySelector('.modal-title')
var modalBodyInput = exampleModal.querySelector('.modal-body input')
modalTitle.textContent = 'New message to ' + recipient
modalBodyInput.value = 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>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>Another override is the option to pop up a modal that covers the user viewport, available via
modifier classes that are placed on a .modal-dialog.
| Class | Availability |
|---|---|
.modal-fullscreen |
Always |
.modal-fullscreen-sm-down |
Below 576px |
.modal-fullscreen-md-down |
