When to use it

E-commerce product cards, shopping cart add actions, any buy/collect CTA needing tactile feedback.

When not to

Passive display contexts — remove the auto-cycle loop before shipping. Avoid on pages with many simultaneous cart actions (no queue).

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change the product emoji to '👟', set the accent color to #a855f7 (update .fly gradient and stroke color), and slow the fly animation to 900ms duration. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

  • fly animation duration (680ms)
  • arc height offset (-50px)
  • product emoji (🎧)
  • accent color (#5cc8ff)
  • badge bounce scale (1.6)
  • idle demo cadence (FIRST=400 / DEMO_EVERY=2800 / IDLE_BACK=3600 ms)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • visibilitychange pause/resume
  • reduced-motion guard (if reduce return)
  • Web Animations API animate() calls
  • IIFE wrapper
  • empty-cart badge state (.badge.empty) — the demo's first-add cue
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Idle demo cycle runs by default (real input takes over, resumes after a few idle seconds) — remove the demo block for purely on-demand interaction
  • No queue: rapid clicks spawn multiple fly elements simultaneously
