It is included here to demonstrate rendering with Material Design for Bootstrap default styling.
See the <ahref="/material-design/buttons">Material Design</a> section for more elements and customization options.

Stylize [the HTML5 `<progress>` element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/progress) with a few extra classes and some crafty browser-specific CSS. Be sure to read up on the browser support.

* Will be replaced with the ToC, excluding the "Contents" header
To caption a progress bar, simply add a `<div>` with your caption text, [align the text using a utility class]({{ site.baseurl }}/components/utilities/#text-alignment), and associate the caption with the `<progress>` element using the `aria-describedby` attribute.
The striped gradient can also be animated. Add `.progress-animated` to `.progress` to animate the stripes right to left via CSS3 animations.
**Animated progress bars do not work in IE9 and Opera 12** – as they don't support CSS3 animations –**nor in IE10+ and Microsoft Edge**– as they currently don't support CSS3 animations on the [`::-ms-fill` pseudo-element](https://msdn.microsoft.com/en-us/library/windows/apps/hh465757.aspx).
