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]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/browsers-devices/#modals-and-dropdowns-on-mobile) for details. +- Due to how HTML5 defines its semantics, [the `autofocus` HTML attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#attr-autofocus) has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript: + +{% highlight js %} +$('#myModal').on('shown.bs.modal', function () { + $('#myInput').trigger('focus') +}) +{% endhighlight %} + +{% include callout-info-prefersreducedmotion.md %} + +Keep reading for demos and usage guidelines. + +## 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).
