Star Morph Loader
A five-point star turns while its inner corners swell out into a pentagon and pull back into a star. Both shapes share one ten-point clip-path polygon, so the tween between them is smooth.
Also known as: star loader, star spinner, clip-path star animation.

}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.
