How this works

Four class-slot rows cascade from translateX(-40px) opacity:0 at 0.15s intervals. Each row is a horizontal stack: time column on the left (large, bold, monospace), class details in the middle, spots-remaining + book button on the right. This time-anchored layout is Peloton/ClassPass's canonical scannable schedule pattern.

High-energy palette — neon lime accent (#a3e635) on charcoal (#1a1a1a) — matches modern fitness industry (Peloton, Barry's, Orangetheory bright accents on dark). Difficulty dots (○○○/●○○/●●○/●●●) provide instant visual difficulty scan. "3 spots left!" scarcity messaging with orange accent triggers urgency without being pushy.

Make it yours

  • Change the vertical from cycling to yoga, HIIT, strength, pilates by editing class names + instructor descriptors.
  • Recolor for a specific brand — Peloton red (#F7462F), SoulCycle yellow (#FBBC17), Equinox black.
  • Add class-photo thumbnails (instructor headshots) on the left instead of time-only columns.
  • For online-only classes, add "Live" + "On-demand" badges instead of physical spot counts.
  • Add difficulty filtering chips at the top that cascade in with the schedule.

Gotchas — read before shipping

  • Time formatting must respect user locale — 24-hour vs 12-hour AM/PM. Use toLocaleTimeString in real production.
  • Spot counts should update in real-time — showing "3 spots left!" that's actually 30 breaks trust after the first booking failure.
  • For pregnant/injured users, ADA best practices recommend clear "Modifications available" tags per class.
  • Class prices should include tax when required by state law (CA, NY, NJ) — surprise tax at checkout kills conversion.
