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](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/progress), 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.
-- The `.progress` wrapper also requires a `role="progress"` and `aria` attributes to make it accessible, including an accessible name (using `aria-label`, `aria-labelledby`, or similar).
+- The `.progress` wrapper also requires a `role="progressbar"` and `aria` attributes to make it accessible, including an accessible name (using `aria-label`, `aria-labelledby`, or similar).
- We use the inner `.progress-bar` purely for the visual bar and label.
- The `.progress-bar` requires an inline style, utility class, or custom CSS to set its width.
- We provide a special `.progress-stacked` class to create multiple/stacked progress bars.
You only set a `height` value on the `.progress` container, so if you change that value, the inner `.progress-bar` will automatically resize accordingly.
