Gradient Sweep

A faceted hex-prism wireframe raked by a rotating spectral gradient band; the lit slice shifts hue continuously via rAF while SMIL drives the sweep rotation.

When to use it

Dark-mode hero backgrounds, tech/sci-fi themes, ambient loading screens needing a focused geometric focal point.

When not to

Light backgrounds (dark navy hardcoded). Contexts requiring legible text overlays — the glow filter competes with content.

Working with an AI agent

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

Change the sweep speed by setting dur="4s" on the animateTransform, and shift the base hue from 100 to 30 (amber) by editing the hue variable and the hsl stop-colors. 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

  • sweep rotation speed (dur='7s' on animateTransform)
  • base hue start (hue=210)
  • hue drift rate (dt*0.05)
  • gradient band width (stop offsets .47/.53)
  • wireframe stroke colors (#2a3050 base, #B1CCA4 accents)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion static fallback branch
  • visibilitychange pause (svg.pauseAnimations/unpauseAnimations + rAF cancel)
  • SVG glow filter (feGaussianBlur + feMerge)
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Background color hardcoded in CSS — must edit to use on non-dark surfaces
  • SMIL animateTransform and rAF hue drift are separate clocks; they can drift out of sync on tab restore
  • Wireframe geometry is computed once at load; not responsive to container resize
