##### Basic Progress Bar Example

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.

##### Progress Bar Height

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

##### Progress Bar Labels

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

##### Multiple bars

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

##### Striped

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

##### 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.

##### Progress Bar Backgrounds

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