Cards

Stacked Peeking Cards

Three layered gradient cards auto-cycle and fan out with a springy rotation on hover; cards spread left and right then restack when cursor leaves.

When to use it

Card collection previews, playlist/deck UI, portfolio thumbnails where showing multiple items in compact space matters.

When not to

Contexts needing legible card content — the fanned back cards are partially obscured. Avoid when auto-cycle motion conflicts with focused reading layouts.

Working with an AI agent

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

Adjust the existing palette tokens and effect parameters while preserving manual control. First deliberate input stops idle demo work while manual feedback finishes. Keep demo-v1 lifecycle marker, __foreverPreview.demoEnabled initialization and forever:interactive handler. Preserve reduced motion, visibility suspension and theme switching.

Safe to edit

  • fan rotation angle (rotate(9deg) / rotate(-9deg))
  • spring duration (--dur-slow: 520ms)
  • card gradient colors (--bg-surface, accent vars)
  • card dimensions (42vmin / 53vmin)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion guard (transition-duration:.001ms)
  • visibilitychange stop/start
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
  • sticky demo-v1 preview lifecycle; stop attract work, retain manual feedback and settling
  • pointer/touch takeover, keyboard access and visibility suspension
  • demo-v1 preview lifecycle: initialize demoEnabled from window.__foreverPreview and stop attract work on the window forever:interactive event; retain manual feedback, settling, cleanup and explicit sessions

Known limitations

  • Card content labels are placeholder text only; real content must be wired in
  • Control state is local to each mount; format changes preserve preview takeover but create a fresh source instance.
  • State remains local to each mounted instance; format/theme remount preserves takeover, not component values.
