- <progress> element didn't allow animation, labels overlaid, multiple bars, etc. - Revamps CSS to use something more similar to v3's implementation - Ditches variant mixin for `bg-` utils - Rebuilds docs to match, including adding a new Height section for customizing that. Only potential remaining todo is adding `.sr-only` instances to within the bar. Unsure if that's necessary.

Use our custom progress component for displaying simple or complex progress bars. We don't use the HTML5 <progress>
element, ensuring you can stack progress bars, animate them, and place text labels over them.

How it works
Progress components are built with two HTML elements, some CSS to set the width, and a few attributes.
- 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 or custom CSS to set their width. - The
.progress-bar
also requires somerole
andaria
attributes to make it accessible.
Put that all together, and you have the following examples.
{% example html %}
Customizing
Customize the appearance of your progress bars with custom CSS, background utilities, stripes, and more.
Labels
Add labels to your progress bars by placing text within the .progress-bar
.
{% example html %}
Height
We only set a height
value on the .progress-bar
, so if you change that value the outer .progress
will automatically resize accordingly.
{% example html %}
Backgrounds
Use background utility classes to change the appearance of individual progress bars.
{% example html %}
Multiple bars
Include multiple progress bars in a progress component if you need.
{% example html %}
Striped
Add .progress-bar-striped
to any .progress-bar
to apply a stripe via CSS gradient over the progress bar's background color.
{% example html %}
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.
Animated progress bars don't work in Opera 12—as they don't support CSS3 animations.
