Spinners

Indicate the loading state of a component or page with boodoo 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

<div class="spinner-border text-primary" 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>

Growing spinner

Use the .spinner-grow for a pulsing, growing indicator.

<div class="spinner-grow text-primary" 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>

Size

Use .spinner-border-sm, .spinner-border-lg, .spinner-grow-sm, .spinner-grow-lg, or configure custom sizes via CSS.

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

Buttons

Use spinners within buttons to indicate an action is processing. The .btn-loading convenience class adds a spinner to any button while preserving its width.

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

<!-- CSS-only loading state -->
<button type="button" class="btn btn-primary btn-loading">Saving...</button>
