Progress components are built with two HTML elements, some CSS to set the width, and a few attributes. We don’t usethe HTML5 <progress> element, ensuring you can stack progress bars, animate them, and place text labels over them.

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

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

We only set a height value on the .progress, so if you change that value the inner .progress-bar will automatically resize accordingly.

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

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

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

The striped gradient can also be animated. Add .progress-bar-animated to .progress-bar to animate the stripes right to left via CSS3 animations.
