CSS Loaders

Design beautiful CSS loading animations.

Style

Live Preview 
.loader {
  width: 64px;
  height: 64px;
  border: 8px solid rgba(79, 70, 229, 0.1);
  border-top-color: #4f46e5;
  border-radius: 50%;
  animation: spin 1s linear infinite;
}

@keyframes spin {
  0% { transform: rotate(0deg); }
  100% { transform: rotate(360deg); }
}

Why CSS Loaders?

Using pure CSS for loading animations is much better than using animated GIFs. CSS animations are resolution-independent (they look crisp on Retina displays), they are fully customizable via CSS variables or utility classes, and they don't require an extra network request to load an image.

Hardware Acceleration

The animations generated by this tool primarily use transform and opacity. These properties can be animated by the GPU in most modern browsers, resulting in silky smooth 60fps animations that don't bog down the main thread.

Accessibility

When implementing loaders, remember to add a visually hidden aria-live="polite" region or role="status" attribute to inform screen readers that content is loading. For example:

<div class="loader" role="status">
  <span class="sr-only">Loading...</span>
</div>
