Spinners

Indicate the loading state of a component or page with CD spinners, built entirely with HTML, CSS, and no JavaScript.

Basic example

Use the border spinners for a lightweight loading indicator.

Regular button

Any single .btn can be turned into a dropdown toggle with some markup changes. Here’s how you can put them to work with either <button>; elements:

“Spinners” can be used to show the loading state in your projects. They’re built only with HTML and CSS, meaning you don’t 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>.

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.

Why not use border-color utilities?:

Each border spinner specifies a transparent border for at least one side, so .border-{color} utilities would override that.

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.

Alignment

Spinners in Bootstrap are built with rems, currentColor, and display: inline-flex. This means they can easily be resized, recolored, and quickly aligned.

Margin

Use margin utilities like .m-5 for easy spacing.

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.
