Tokens drip into an isometric bucket on a steady beat. A burst of requests spends them one per pass at the gate, and once it is empty the next request bounces off in the accent.

Also known as: rate limiter animation, token bucket animation, api rate limit diagram, throttling animation.

Customizing this snippet

  • Color: set --hln-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --hln-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
  • Speed: change the duration on the transition or animation shorthand. Staggered delays are relative, so they keep their rhythm.
  • Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
