Spinners
Indicate the loading state of a component or page with Bootstrap spinners, built entirely with HTML, CSS, and no JavaScript.
About
Bootstrap spinners can be used to show the loading state in your projects. They are built only with HTML and CSS, meaning you do not need any JavaScript to create them. You will, however, need some custom JavaScript to toggle their visibility. Their appearance, alignment, and sizing can be easily customized with our amazing utility classes.
For accessibility purposes, each loader here includes <role="status"> and a nested <span class="visually-hidden">Loading...</span>.
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 do not fancy a border spinner, switch to the grow spinner. While it does not technically spin, it does repeatedly grow!
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.

Output:
