Use background utility classes to change the appearance of individual progress bars.
Add labels to your progress bars by placing text within the .progress-bar.
We only set a height value on the .progress, so if you change that value the inner .progress-bar will automatically resize accordingly.
Add .progress-bar-striped to any .progress-bar to apply a stripe via CSS gradient over the progress bar’s background color.
Include multiple progress bars in a progress component if you need.
The striped gradient can also be animated. Add .progress-bar-animated to .progress-bar to animate the stripes right to left via CSS3 animations.
