Rotating Dots Loader

Three dots in a row, the middle one larger, spin a full turn with a strong ease so they whip around and rest flat for a beat. A single keyframe on the wrapper; the dots themselves never animate.

Also known as: spinning three dots, propeller dots loader, rotating ellipsis.

Tailwind CSS version

The same loader using only Tailwind's built-in animation utilities. No custom keyframes or config needed.

<div class="flex h-12 w-12 animate-[spin_1.2s_cubic-bezier(0.7,0,0.3,1)_infinite] items-center justify-center gap-[5px]" role="status" aria-label="Loading">
  <span class="h-[11px] w-[11px] rounded-full bg-blue-500"></span>
  <span class="h-[14px] w-[14px] rounded-full bg-blue-500"></span>
  <span class="h-[11px] w-[11px] rounded-full bg-blue-500"></span>
</div>

Customizing this loader

  • Color: set --ldr-color on the element or a parent. Currently previewing #3b82f6.
  • Size: set --ldr-size. Every dimension in the snippet is derived from it. Currently previewing 64px.
  • Speed: change the duration on the animation shorthand. Delays on the children are relative, so they keep their rhythm.
  • Accessibility: the root carries role="status" and an aria-label so screen readers announce the wait. The reduced-motion rule at the end slows the animation for users who asked for less motion.
