Inputs & Switches

Checkbox Morph

Three native amber checkbox buttons animate their check strokes and expose pressed state. First input stops the demo; checked values remain.

When to use it

Settings panels, form demos, or any UI showcase needing a tactile checkbox feel with ambient motion.

When not to

Production forms requiring immediate user control — remove the auto-cycle clock loop before shipping.

Working with an AI agent

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

Change accent from amber to teal (#2dd4bf), increase checkbox count from 3 to 5, and slow the checkmark stroke to 0.10 lerp factor. 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

accent color (#ffb02e)
checkbox count (loop 0..3)
auto-cycle interval (clock%150)
checkmark lerp speed (0.18)
corner radius (rx=20)
theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

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

First deliberate input permanently disables idle demo; manual input, finite feedback and settling remain active. Host demoEnabled=false skips the initial attract cycle.
LEN=80 is an approximation; exact path length may cause slight overshoot on the stroke draw
State remains local to each mounted instance; format/theme remount preserves takeover, not component values.
