CSS 3D & Perspective

Floating Coin

A glossy gold coin spins on its Y-axis and bobs up/down with a reactive shadow; pointer X position adjusts spin speed in real time.

When to use it

Game UIs, reward/achievement screens, crypto/NFT landing pages, or any dark-theme hero needing a tactile 3D object.

When not to

Light backgrounds (dark amber is hardcoded). Contexts where constant rotation is distracting alongside body text.

Working with an AI agent

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

Change the front face star emoji to '💎', set the base spin speed to 2.5 (spin variable), and update the background to #0d1b2a for a night-blue theme. 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

  • base spin speed (spin=1.6)
  • bob amplitude (Math.sin(t)*4)
  • coin size (34vmin)
  • front/back face content (★ / 3D)
  • background color (#1b1405)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • prefers-reduced-motion guard + static fallback
  • visibilitychange stop/start pair
  • transform-style:preserve-3d on #coin and #wrap
  • backface-visibility:hidden on .face
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Coin size in vmin — may appear too large on ultra-wide viewports
  • No click interactivity; pointer only affects spin speed, not state
  • Background color hardcoded in CSS body rule

More CSS 3D & Perspective components

  • Rotating CubeGlowing sage-green wireframe cube slowly auto-rotates in CSS 3D with a subtle sine-wave tilt; pointer movement offsets the rotation to follow the cursor.
  • 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.
  • Folding Paper4-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.
  • 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.
