Basic
Progress components are built with two HTML elements, some CSS to set the width, and a few attributes, ensuring you can stack progress bars, animate them, and place text labels over them.
Backgrounds
Use background utility classes to change the appearance of individual progress bars.
Gradient Backgrounds
Gradient background was able to apply to progress bar as well.
Sizing
Use .progress-sm, .progress-lg or .progress-xl to customize progress size
Multiple bars
Include multiple progress bars in a progress component if you need.
