Progress
How it works
A progress bar can be used to show a user how far along he/she is in a process.
Backgrounds Color
Use background utility classes to change the appearance of individual progress bars.
Striped Progress Bar
Add .progress-bar-striped to any .progress-bar to apply a stripe via CSS gradient
over the progress bar’s background color.
Height
We only set a height value on the .progress, so if you change that value the inner
.progress-bar will automatically resize accordingly. Use .progress-xs, .progress-sm,
.progress-md, .progress-lg or .progress-xl classes.
