--- layout: docs title: Progress description: Documentation and examples for using Bootstrap custom progress bars featuring support for stacked bars, animated backgrounds, and text labels. group: components toc: true --- ## How it works Progress components are built with two HTML elements, some CSS to set the width, and a few attributes. We don't use [the HTML5 `` element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/progress), ensuring you can stack progress bars, animate them, and place text labels over them. - We use the `.progress` as a wrapper to indicate the max value of the progress bar. - We use the inner `.progress-bar` to indicate the progress so far. - The `.progress-bar` requires an inline style, utility class, or custom CSS to set their width. - The `.progress-bar` also requires some `role` and `aria` attributes to make it accessible. Put that all together, and you have the following examples. {% example html %}

{% endexample %} Bootstrap provides a handful of [utilities for setting width]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/sizing/). Depending on your needs, these may help with quickly configuring progress. {% example html %}

{% endexample %} ## Labels Add labels to your progress bars by placing text within the `.progress-bar`. {% example html %}

{% endexample %} ## Height We only set a `height` value on the `.progress`, so if you change that value the inner `.progress-bar` will automatically resize accordingly. {% example html %}

{% endexample %} ## Backgrounds Use background utility classes to change the appearance of individual progress bars. {% example html %}

{% endexample %} ## Multiple bars Include multiple progress bars in a progress component if you need. {% example html %}

{% endexample %} ## Striped Add `.progress-bar-striped` to any `.progress-bar` to apply a stripe via CSS gradient over the progress bar's background color. {% example html %}

{% endexample %} ## Animated stripes The striped gradient can also be animated. Add `.progress-bar-animated` to `.progress-bar` to animate the stripes right to left via CSS3 animations. **Animated progress bars don't work in Opera 12**—as they don't support CSS3 animations.
