How this works

The radial burst gives each of twelve .piece children its own keyframe (kf-23-p1 through kf-23-p12) that translates to a unique end position like translate(-100px, -130px) rotate(540deg). Each piece starts at 50%, 50% and explodes outward, fading opacity: 1 → 0 as it travels. A --d custom property staggers their start times slightly via animation-delay: calc(var(--d) * 0.08s).

The rain scene reuses the same pieces but with a single shared kf-23-rain that translateY: 0 → 280px over 2.5s linear, with each piece offset horizontally via left and given different durations and delays to break up the cadence. The popper has a central icon that rotates ±20deg while eight surrounding pieces explode outward via per-piece end-position keyframes.

Make it yours

  • Increase piece count by duplicating the div.piece elements and writing matching kf-23-pN keyframes with unique end positions.
  • Speed up the burst by changing animation-duration: 2s to 1.2s on the .scene-1 .piece rule.
  • Recolour confetti via the hex values in the nth-child selectors — #f7c948, #e91e8c, #7c6af7, etc.
  • Loop the burst by leaving animation: ... infinite; for one-shot, remove infinite and trigger via JS.
  • Adjust rain fall distance by changing translateY(280px) to translateY(400px) for taller containers.

Gotchas — read before shipping

  • Twelve unique keyframes per scene is heavy — for production confetti, use a single parameterised keyframe with --tx/--ty custom properties (see demo 06).
  • Infinite-looping confetti loses the celebratory effect and becomes ambient noise — best as a one-shot triggered by user action.
  • Animating top/left in the popper triggers layout per frame; swap to transform: translate() for hot paths.
