How it works
Indicate the loading state of a component or page with Bootstrap spinners, built entirely with HTML, CSS, and no JavaScript.
Basic Example
Use the border spinners for a lightweight loading indicator.

Growing spinner
If you don’t fancy a border spinner, switch to the grow spinner. While it doesn’t technically spin, it does repeatedly grow!

Size
Add .spinner-border-sm
and .spinner-grow-sm
to make a smaller spinner that can quickly be used within other components.

Buttons
Use spinners within buttons to indicate an action is currently processing or taking place. You may also swap the text out of the spinner element and utilize button text as needed.
