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 >}}

{{< /example >}}

Bootstrap provides a handful of utilities for setting width. Depending on your needs, these may help with quickly configuring progress.

{{< example >}}

{{< /example >}}

Labels

Add labels to your progress bars by placing text within the .progress-bar.

{{< example >}}

25%
{{< /example >}}

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 >}}

{{< /example >}}

Backgrounds

Use background utility classes to change the appearance of individual progress bars.

{{< example >}}

{{< /example >}}

Multiple bars

Include multiple progress bars in a progress component if you need.

{{< example >}}

{{< /example >}}

Striped

Add .progress-bar-striped to any .progress-bar to apply a stripe via CSS gradient over the progress bar's background color.

{{< example >}}

{{< /example >}}

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.

Toggle animation
<div class="progress">
  <div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
</div>
