Border spinner
Use the border spinners for a lightweight loading indicator.
Colors
The border spinner uses currentColorfor 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!
Colors
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.
Margin
Use margin utilities like .m-5for easy spacing.
Placement
Use flexbox utilities,float utilities,or text alignment utilities to place spinners exactly where you need them in any situation.
Size
Add .spinner-border-smand .spinner-grow-smto 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.
