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 .progressas a wrapper to indicate the max value of the progress bar.
• We use the inner .progress-barto indicate the progress so far.
• The .progress-barrequires an inline style,utility class,or custom CSS to set their width.
• The .progress-baralso requires some roleand ariaattributes to make it accessible.

Put that all together,and you have the following examples.

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

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

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

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-stripedto any .progress-barto apply a stripe via CSS gradient over the progress bar’s background color.
