Spinner
Indicate the loading state of a component or page with Bootstrap spinners, built entirely with HTML, CSS, and no JavaScript.
Border spinner
Use the border spinners for a lightweight loading indicator.
Colors
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!
Once again, 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.
Flex
Use flexbox utilities to place spinners exactly where you need them in any situation.
Floats
Use float utilities to place spinners exactly where you need them in any situation.
Text align
Use text alignment utilities to place spinners exactly where you need them in any situation.
Size
Add .spinner-border-sm and .spinner-grow-sm to make a smaller spinner that can quickly be used within other components.
Or, use custom CSS or inline styles to change the dimensions as needed.
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.
