How this works

Nine spinner variants share a single grid cell layout but each runs its own keyframe. The classic ring uses a transparent border with one coloured edge and a linear 360deg rotation, while the dual ring stacks two absolutely-positioned ::before/i elements and counter-rotates the inner one with animation-direction: reverse. The morph cell animates border-radius and scaleX through four steps so a square becomes a circle and back.

Pulse dots, wave bars, and folding squares all rely on staggered animation-delay across sibling spans to create the chase effect. The comet uses a conic-gradient mask with transparent → coloured stops, spun via linear timing so the tail looks continuous. Only transform and opacity are animated, which keeps every spinner on the compositor.

Make it yours

  • Swap the colour palette by editing the --purple, --pink, --cyan custom properties at the .kf-01 root.
  • Slow every spinner uniformly by multiplying each animation-duration (default .9s on the ring) by 1.5 for a calmer feel.
  • Change the ring thickness with border-width: 6px on .kf-01__ring and bump the size to 80px for hero placements.
  • Replace the pulse-dot count by adding/removing span children and extending the nth-child delay rule (.2s steps).
  • Change the comet sweep angle by editing the conic-gradient(transparent 60%, var(--pink)) stop from 60% to 75% for a longer tail.

Gotchas — read before shipping

  • The conic-gradient comet renders softly in older Safari; below 12.1 it falls back to a flat colour with no tail visible.
  • Stacking nine infinite animations on one page costs paint budget — keep them off-screen on mobile or pause via animation-play-state when not visible.
  • The prefers-reduced-motion media query kills all spinners but leaves the static label visible; show a fallback skeleton if these are gating a UI state.
