When to use it

Icon-only buttons needing a label reveal, favorites or bookmark actions, any UI where a tooltip clarifies an ambiguous control.

When not to

Touch-only interfaces where hover is unavailable; layouts where there is no room above the button for the tooltip to appear.

Working with an AI agent

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

Change tooltip text to 'Save for later', update accent color from #4fe0c0 to #a78bfa, and slow the spring transition to 0.36s. 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

  • tooltip label text (#tip inner text)
  • accent color (#4fe0c0)
  • spring easing (cubic-bezier(.2,1.5,.4,1))
  • tooltip offset (bottom: calc(100% + 14px))
  • idle demo cadence (first pop after 400 ms, then alternates every 1700 ms)
  • button size (54px)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • reduced-motion guard (reduce var)
  • visibilitychange pause (clearInterval)
  • IIFE wrapper
  • pointerenter/pointerleave listeners
  • hover takeover (hover flag: the demo never toggles under a real pointer)
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Idle demo cycle runs by default (real input takes over, resumes after a few idle seconds) — remove the demo block for purely on-demand interaction
  • Tooltip position is hardcoded above the button; may clip at top of viewport
  • Button div lacks aria role and aria-label — add for production accessibility
