How this works

Questions are absolutely-stacked panels; the active one slides in with a translateY + opacity keyframe while a thin top progress bar fills per answer. Choice questions auto-advance after a 350 ms confirmation tint — one decision, zero extra clicks.

The NPS row is a radio group of 11 real inputs, so arrow keys work natively; a keydown listener additionally maps 0–9 to instant answers. The final free-text step is optional with a visible character counter, and the whole survey reports state to an aria-live region ("Question 2 of 4") so the pace is perceivable non-visually.

Make it yours

  • Reorder or add questions by moving whole <section data-q> blocks — progress and counters recount automatically.
  • Swap faces for text labels for enterprise tone.
  • Change the auto-advance delay via ADVANCE_MS (or set 0 to require the arrow button).
  • Recolour with --vio; the tint, bar and rings derive from it.

Gotchas — read before shipping

  • Auto-advance too fast (<300ms) feels like the UI stole the click — users need to see their selection register.
  • Keep 0–10 as radios, not buttons: arrow-key group semantics and form serialization come free.
  • Never require the free-text question; optional endings measurably raise completion of the questions that matter.

Browser support

ChromeSafariFirefoxEdge
111+16.2+121+111+

Floor set by :has(), oklch(), color-mix() as this demo is written. The core technique itself goes back further — Chrome 105+.

:has() tints selected choices; view-transition-free — animations are plain CSS keyframes so they run identically everywhere current.
