Use Bootstrap’s JavaScript modal plugin to add dialogs to your site for lightboxes, user notifications, or completely custom content.
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.
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.
Static backdrop
When backdrop is set to static, the modal will not close when clicking outside it. Click the button below to try it.
Scrolling 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.
You can also create a scrollable modal that allows scroll the modal body by adding .modal-dialog-scrollable
to .modal-dialog
.
Vertically centered
Add .modal-dialog-centered
to .modal-dialog
to vertically center the modal.
Tooltips 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-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
.
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.
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.
Fullscreen Modal
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
|
