Bauhaus Geometric

Stage Reveal

Eight colored bars split left/right like a stage curtain to reveal a primary-red circle with a gold ring, then close again in a 4.6s loop.

When to use it

Hero sections needing dramatic geometric reveals, Bauhaus/constructivist aesthetic pages, loading or intro animations.

When not to

Contexts requiring immediate content visibility — curtain obscures center for first 50% of each cycle. Avoid on slow connections where CSS animation may stutter.

Working with an AI agent

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

Change the revealed circle color to #1f4ea8 (Bauhaus blue) and slow the cycle to 6s by updating animation-duration from 4.6s to 6s on all animation rules. 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

  • curtain bar colors (fill attributes on rect elements)
  • animation duration (4.6s on all keyframe rules)
  • circle fill color (#e63329)
  • ring color (#f4c20d stroke)
  • curtain slide distance (118% in keyframes)
  • stage cycle pacing (curtain/actor timing in the loop — re-paced so the stage moves within the first 3 s)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • bh11-L / bh11-R transform-origin split (left center / right center)
  • prefers-reduced-motion static fallback block
  • visibilitychange pause handler
  • IIFE wrapper
  • continuous stage loop (paused on visibilitychange)
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • All animations share a single 4.6s duration — changing speed requires updating every animation-duration declaration
  • Background color is hardcoded in both CSS and SVG rect — must edit both to change it
