Do you know the latest update of 2022? 🎉 Our roadmap is alive for future updates.

Modal

Use Bootstrap’s JavaScript modal plugin to add dialogs to your site for lightboxes, user notifications, or completely custom content.

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.

                            
                        

Toggle between modals

Toggle between multiple modals with some clever placement of the data-bs-target and data-bs-toggle attributes. For example, you could toggle a password reset modal from within an already open sign in modal. Please note multiple modals cannot be open at the same time—this method simply toggles between two separate modals.

Open first modal
                            
                        

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.handleUpdate() to readjust the modal’s position in case a scrollbar appears.

Accessibility

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

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.

                            
                        

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 Always
.modal-fullscreen-sm-down Below 576px
.modal-fullscreen-md-down Below 768px
.modal-fullscreen-lg-down Below 992px
.modal-fullscreen-xl-down Below 1200px
.modal-fullscreen-xxl-down Below 1400px
