Rotating Lines Grid Loader
A three by three grid of short dashes, each spinning a full turn in a diagonal wave from the top left corner. Uses the stock spin keyframes with strong easing, so it ports to Tailwind as is.
Also known as: line grid loader, spinning dashes loader.

Customizing this loader
- Color: set
--ldr-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--ldr-size. Every dimension in the snippet is derived from it. Currently previewing64px. - Speed: change the duration on the
animationshorthand. Delays on the children are relative, so they keep their rhythm. - Accessibility: the root carries
role="status"and anaria-labelso screen readers announce the wait. The reduced-motion rule at the end slows the animation for users who asked for less motion.
