How this works

Two dots each render several particles via stacked box-shadow clones; a one-shot keyframe scales and fades them outward from the centre.

Make it yours

  • Extend the box-shadow clone list.
  • Recolour and vary offsets.
  • Change reach via the translate distance.
  • Fire on click via :active.

Gotchas — read before shipping

  • Keep clone counts sensible for paint cost.
  • Particles pointer-events:none.
  • Use a one-shot animation.

Floor set by oklch() as this demo is written. The core technique itself goes back further — Chrome 36+.

Multi-value box-shadow + keyframes are universal; without CSS a clean CTA.
