How it works

Before getting started with Bootstrap’s modal component, be sure to read the following as our menu options have recently changed.

Modal for more bootstrao components Bootstrap Modal documentation

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:

var myModal = document.getElementById('myModal')
var myInput = document.getElementById('myInput')

myModal.addEventListener('shown.bs.modal', function () {
    myInput.focus()
})

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-body">
                <p>Woohoo, you're reading this text in a modal!</p>
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>

            </div>
        </div>

Static backdrop

When backdrop is set to static, the modal will not close when clicking outside it. Click the button below to try it.

Vertically centered

Add .modal-dialog-centered to .modal-dialog to vertically center the modal.

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`
Fullscreen	`.modal-fullscreen`	`Always`
