Material Ripple

Dark rounded button that spawns an expanding ink ripple from the tap point; idles by firing ripples from random positions every 1.5 s.

When to use it

CTA buttons, action triggers, any click surface needing tactile feedback with a material-design feel.

When not to

Auto-cycling demo ripple must be removed before production use; not suitable where motion is distracting or backgrounds are light.

Working with an AI agent

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

Change the ripple color from teal/cyan to gold by editing the radial-gradient in .c04-rip__ink background to rgba(255,180,0,0.55), rgba(255,220,80,0.15), and slow the spread to 800ms via --dur-slow. 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

  • ripple color (radial-gradient in .c04-rip__ink)
  • ripple spread duration (--dur-slow: 520ms)
  • ripple size multiplier (2.2 in JS)
  • autonomous preview cycle that stops at first deliberate input interval (1500ms in setTimeout)
  • button padding and border-radius (--r-md)
  • autonomous preview until first deliberate input cadence (LEAD=400 / DEMO_EVERY=2500 / IDLE_RESUME=3600 ms, TICK=100)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • overflow:hidden on .c04-rip (clips ripple)
  • IIFE wrapper
  • reduced-motion guard (animation-duration:.001ms + early return in loop)
  • visibilitychange pause
  • idle demo ripple (the same ripple() a tap runs; real input takes over)
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
  • 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

  • Auto-cycling autonomous preview cycle that stops at first deliberate input must be removed or stopped before shipping in production
  • Ripple colour lives in the --ink-a/--ink-b tokens (dark in :root, light in [data-theme=light]) — edit both blocks to restyle
  • State remains local to each mounted instance; format/theme remount preserves takeover, not component values.
