Modal
Nova uses Bootstrap’s modal plugin, so add dialogs to your site for lightboxes, user notifications, or completely custom content.
How it works
- 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.modalwithin 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')
})

Example
<!-- Modal -->
<div id="exampleModal" class="modal fade" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog rounded py-5" role="document">
<div class="modal-content py-5">
<header class="modal-header flex-column justify-content-center border-0 mb-3 mb-xl-5">
<h4 id="exampleModalLabel" class="modal-title mx-auto">Modal title</h4>
</header>
<div class="modal-body pt-3 mb-5 mb-md-7 text-center">
<p>Modal body text goes here.</p>
</div>
<footer class="modal-footer justify-content-between border-0">
<p>Modal footer text goes here.</p>
</footer>
</div>
</div>
</div>
<!-- End Modal -->
Usage
The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds .modal-open to the <body> 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.
<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
