Documentation

Spinners

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.

<div class="spinner-border" role="status">
    <span class="visually-hidden">Loading...</span>
</div>

Colors

The border spinner uses currentColor for its border-color, meaning you can customize the color with text color utilities.

<div class="spinner-border text-primary" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-secondary" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-success" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-danger" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-warning" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-info" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-light" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-dark" role="status">
    <span class="visually-hidden">Loading...</span>
</div>

Growing spinner

If you don’t fancy a border spinner, switch to the grow spinner. 

<div class="spinner-grow" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-primary" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow  text-secondary" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow  text-success" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow  text-danger" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow  text-warning" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow  text-info" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow  text-light" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow  text-dark" role="status">
    <span class="visually-hidden">Loading...</span>
</div>

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

<div class="spinner-border m-5" role="status">
  <span class="visually-hidden">Loading...</span>
</div>

Placement

Use flexbox utilities, float utilities, or text alignment utilities to place spinners exactly where you need them in any situation.

Flex
<div class="d-flex justify-content-center">
  <div class="spinner-border" role="status">
    <span class="visually-hidden">Loading...</span>
  </div>
</div>
Floats
<div class="clearfix">
    <div class="spinner-border float-end" role="status">
        <span class="visually-hidden">Loading...</span>
    </div>
</div>
Text align
<div class="text-center">
  <div class="spinner-border" role="status">
    <span class="visually-hidden">Loading...</span>
  </div>
</div>

Size

Add .spinner-border-sm and .spinner-grow-sm

<div class="spinner-border spinner-border-sm" role="status">
    <span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow spinner-grow-sm" role="status">
    <span class="visually-hidden">Loading...</span>
</div>

Buttons

Use spinners within buttons to indicate an action is currently processing or taking place.

<button class="btn btn-primary" type="button" disabled>
    <span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span>
        <span class="visually-hidden">Loading...</span>
