Stylize the HTML5 <progress> element with a few extra classes and some crafty browser-specific CSS. Be sure to read up on the browser support.

Example

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.

IE9 support

Internet Explorer 9 doesn't support the HTML5 <progress> element, but we can work around that.

{% example html %}

Contextual alternatives

Progress bars use some of the same button and alert classes for consistent styles.

{% example html %} {% endexample %}

Striped

Uses a gradient to create a striped effect.

{% example html %} {% endexample %}

Animated stripes

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.
