CSS 3D & Perspective

Folding Paper

4-panel paper accordion folds and unfolds in a zig-zag CSS 3D motion, slowly rotating on a dark green background. Cream front and sage back faces alternate.

When to use it

Ambient hero backgrounds, paper-craft or origami themes, portfolios needing calm 3D motion without user interaction.

When not to

Contexts where CSS 3D perspective causes z-fighting on older GPUs, or where subtle motion is needed — the continuous fold cycle is always visible.

Working with an AI agent

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

Change panel count from 4 to 6 by setting P=6, widen each panel to 14vmin, and shift accordion colors to warm terracotta (#c87941) front and dusty rose (#b07070) back. 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

  • panel count (P=4)
  • panel dimensions (11vmin wide, 30vmin tall)
  • fold angle limit (ang=f*165)
  • animation speed (t+=0.011)
  • front/back face gradient colors
  • root rotation range (-20+f*40 deg)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • transform-style:preserve-3d on .panel
  • visibilitychange pause/start
  • prefers-reduced-motion guard with static frame
  • IIFE-style scoped variable block
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Panel count beyond 6-7 may cause perspective clipping at edges
  • No touch/pointer interaction — purely passive
  • Background color hardcoded in CSS body rule

  • Card Deck FanSeven gold-and-mauve playing cards fan open and closed in a sine-wave 3D arc using CSS rotateZ and perspective transform.
  • Coverflow RingEight vivid gradient cards orbit in a 3D coverflow ring with CSS perspective and per-card reflections. Pointer X position steers rotation speed.
  • Isometric Blocks3x3 grid of soft lilac CSS 3D cubes bobs in a staggered sine wave on a dark lilac-tinted ground. Three shaded faces per cube simulate isometric lighting.
  • Parallax DepthA glowing sun with colored orbiting dots on layered CSS 3D planes that tilt and parallax toward the pointer; auto-orbits until interaction.
  • Wireframe GlobeA teal wireframe globe of 6 longitude and 5 latitude rings rotates in CSS 3D perspective; pointer steers spin speed and tilt angle.
