Loaders

Create a pure CSS loader by applying the loader class to an empty <span> element. You can use the loader-small and loader-big modifiers to change the size.

<span class="loader loader-small"></span>
<span class="loader"></span>
<span class="loader loader-big"></span>

Background Loaders

You can simulate a background loader using loader-bg. This is achieved using position: relative on the container and the ::after pseudo-element. You can use the loader-bg-small and loader-bg-big modifiers to change the size.

<div class="loader-bg loader-bg-small"></div>
<div class="loader-bg"></div>
<div class="loader-bg loader-bg-big"></div>

Variations

Use the loader-* modifier to create variations.

<span class="loader loader-secondary"></span>
<span class="loader loader-success"></span>
<span class="loader loader-info"></span>
<span class="loader loader-warning"></span>
<span class="loader loader-danger"></span>
<span class="loader loader-light"></span>
<span class="loader loader-dark"></span>
