Yin Yang Spinner
A yin yang symbol turning with a slow start and a soft stop each revolution. Drawn as one SVG path with an even-odd hole for the inner dot, so both halves stay crisp on any background.
Also known as: yin yang loader, taijitu spinner, balance loading animation.

- 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.
