How this works

The progress bar is segmented — one pill per step — so users can literally count what's left, which tests better than an anonymous percentage on short flows. Steps that consist of a single radio-card choice auto-advance ~300 ms after selection (with a paused version for reduced-motion users), removing an entire click per screen.

The ZIP-first pattern is deliberate conversion engineering: commit users with a trivially easy first field, then escalate. Each screen keeps exactly one decision, and the trust footer ("takes 2 minutes · no spam calls") stays pinned under every step.

Make it yours

  • Disable auto-advance by removing the setTimeout in the change handler if your users prefer explicit Continue taps.
  • Add vehicle make/model steps by cloning a radio-card fieldset — the segment bar recounts automatically.
  • Adjust the escalation order: cheapest-to-answer questions always go first.
  • Retheme via --teal; the segments, cards and CTA all derive from it.

Gotchas — read before shipping

  • Auto-advance must never fire on keyboard arrow-cycling through radios — advance on click of the label or after a debounce, and always keep the Continue button as fallback.
  • Keep the back button visible even on step 2; trapping users kills trust on insurance forms.
  • ZIP validation: inputmode="numeric" + pattern, never type="number" (leading zeros get stripped).
  • Compliance callout — state insurance producer licensing (NAIC + state DOI) requires the licensed-agent name and license number on any binding quote page; a callback opt-in for follow-up needs TCPA 47 CFR 64.1200 prior express written consent as its own checkbox, not bundled into the Continue button.

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

:has() drives checked-card styling; the rest is evergreen. Without :has() the radios still work — selection shows via the native focus ring.
