Dot Tunnel Loader
Rings of dots rush toward you out of a vanishing point and twist as they pass, like flying down a tunnel. Each ring is a dotted border, so the dots grow with perspective for free.
Also known as: warp speed loader, hyperspace tunnel animation, dotted rings zoom.

}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.
