How this works

Every choice control here is the hidden-input + :has(:checked) pattern: segmented cards for single-choice (company size, budget), chips for multi-choice (goals — real checkboxes, so multiple can be on). The final step renders time-slot pills as one radio group so exactly one slot can be picked with mouse or arrow keys.

The step counter is plain text ("Step 2 of 4") beside a thin bar — B2B audiences skim; explicit numbers beat decoration. A summary chip row above the booking step echoes back what the lead selected, confirming the routing feels personalised.

Make it yours

  • Wire the slot pills to your real scheduling API; each pill is just a radio with a datetime value.
  • Add disqualification logic: route budgets under a floor to a resources page instead of the calendar.
  • Extend the goals chips freely — checkboxes wrap automatically.
  • The neutral palette maps 1:1 onto Tailwind's slate/indigo scales if you're porting.

Gotchas — read before shipping

  • Multi-select chips must be checkboxes, not radios, and each needs its own label wrapping — grouping them under one label breaks per-chip toggling.
  • Echo selections in the summary from live form state, not hardcoded strings, or the personalisation lie is obvious.
  • Keep 'Step n of N' in an aria-live="polite" element so the count is announced as it changes.

Browser support

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

:has() checked-styling everywhere; grid + logical properties otherwise. Chips fall back to native checkboxes with focus rings on older engines.
