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 <progress> element, 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 %}

25%

{% 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.
