Auto-hide Dock

A desktop with a window, and a dock that lives just below the bottom edge: it slides up when the pointer reaches the lowest 14% of the screen and drops away when it leaves; a ringed demo cursor glides to the edge and away on a loop until the real pointer takes over.

When to use it

Immersive or content-first screens (viewers, editors, kiosks) where navigation should stay out of the way until summoned; onboarding demos of an edge gesture.

When not to

Touch-first products (there is no edge to hover) and pages where the dock must be discoverable without a demo.

Working with an AI agent

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

Change the reveal threshold with EDGE (0.86 = bottom 14%); remove the demo cursor by deleting the KEY path and calling screen.classList.add('is-show') in start(); restyle the window through --win/--win-bar/--txt. 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

  • reveal threshold (EDGE=0.86)
  • demo cursor path and loop length (KEY keyframes, the 4.6 s period)
  • dock items and gradients (--g1…--g5)
  • the window dressing (.c13-win, .c13-chip)
  • slide timing (transition 380ms)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • place() applying the same EDGE rule to the demo cursor and the real pointer
  • IIFE wrapper
  • visibilitychange stop/start of the rAF loop
  • prefers-reduced-motion guard (dock simply shown, no cursor)
  • cursor:none on the screen so the demo cursor is the only one
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Hover-only reveal — no touch equivalent; the demo loop is what mobile visitors see
  • The demo cursor is a styled span, not the system cursor, so it cannot click anything
  • Light re-theme via the [data-theme=light] token block; catalog bg/accent describe the dark default

  • Magnify DockmacOS-style frosted-glass dock of six gradient tiles that scale up and lift toward the cursor; idle auto-sweep keeps it animated when untouched.
  • Hamburger MorphThree-line hamburger button spring-morphs into a glowing teal X on click; button border gains teal glow when open. Auto-cycles as demo.
  • Gooey Tab BarPill-shaped tab bar with a vermillion blob that slides between tabs using a spring easing and SVG goo filter for liquid merge effect on dark surface.
  • Radial Fan MenuA core button rotates to an X and fans five glowing stone-toned icon petals outward in a staggered spring arc; auto-cycles open/close as a demo.
  • Slide-in DrawerHamburger icon morphs to an X while a side panel slides in over a dark scrim, revealing four nav items with staggered fade-in animations.
  • Underline FollowA glowing emerald-to-tan gradient underline slides and resizes to follow hovered nav links; wanders idly across links when unhovered.
