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 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.
