Spokes Spinner
Eight rounded spokes fade in turn around a center point, the pattern iOS and macOS use for activity indicators. Rotation is faked with opacity, so it is very cheap to render.
Also known as: iOS spinner, Apple activity indicator.

- 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.
