Use the border spinners for a lightweight loading indicator.
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.
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.
Spinners in Bootstrap are built with rems, currentColor, and display: inline-flex. This means they can easily
be resized, recolored, and quickly aligned.
Use margin utilities like .m-5 for easy spacing.
Use flexbox utilities, float utilities, or text alignment utilities to place spinners exactly where you need them in any situation.
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.
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.
