Border Spinner
Use the border spinners for a lightweight loading indicator.
Color Spinner
The border spinner uses currentColor for its border-color, meaning you can customize the color with text color utilities. You can use any of our text color utilities on the standard spinner.
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!
Color Growing Spinner
This spinner is built with currentColor, so you can easily change its appearance with text color utilities. Here it is in blue, along with the supported variants.
Alignment
Spinners in Bootstrap are built with rems, currentColor, and display: inline-flex. This means they can easily be resized, recolored, and quickly aligned.
Placement
Use flexbox utilities, float utilities or text alignment utilities to place spinners exactly where you need them in any situation.
Sizes
Add .spinner-border-sm and
.spinner-border.avatar-**
to make a smaller spinner that can quickly be used within other components.
Buttons Spinner
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.
