How this works

Each ticker is one flex row with width: max-content containing the content duplicated end-to-end. The kf-18-scroll-l keyframe translates transform: translateX(0 → -50%) with linear timing, so when the first copy scrolls off the left, the second copy is already filling the right edge — creating a seamless infinite loop.

Different rows run at different durations (stock at 30s, brands at 20s, words at 18s, news at 40s) for visual variety. Word row 2 uses kf-18-scroll-r which animates -50% → 0 for the opposite direction. The brand marquee adds gradient fades on the edges via ::before/::after overlays, hiding the loop-seam visual artifact. :hover { animation-play-state: paused } stops the stock ticker for readability.

Make it yours

  • Change scroll speed by editing the duration — 30s on the stock row → 15s for a faster feed.
  • Reverse direction by swapping kf-18-scroll-l for kf-18-scroll-r on the target row.
  • Recolour the news bar via the --blue and --yellow custom properties on .kf-18.
  • Drop the edge fade-out by removing the ::before/::after rules on .kf-18__brands.
  • Adjust pause-on-hover by adding animation-play-state: paused to :hover on any other ticker row.

Gotchas — read before shipping

  • The content must be duplicated exactly — if you add an item to the first copy and forget the second, you get a visible jump on each loop.
  • linear timing is required for a seamless loop; ease creates a visible deceleration at the wrap point.
  • On mobile, four concurrent infinite scrolls hammer the GPU — disable two of them at (max-width: 640px).
