```How this works
Two visually-hidden <input type=radio> (Monthly / Yearly) sit before their labels inside one role=group track. A ::after-free sliding thumb is a real <span> that the track translates with :has(): .track:has(#yearly:checked) .thumb{translate:100% 0}. No JS state — the checked radio IS the state.
The magic users love is the price swap. Each price cell holds a monthly figure and a yearly figure stacked; a container-level :has(#yearly:checked) fades one out and the other in, and a small "save 20%" badge only appears on Yearly. Because the values are real DOM text, they are crawlable and announced correctly.
.btn-04__track:has(#btn-04-y:checked) .btn-04__thumb{ translate:100% 0 }
.btn-04__card:has(#btn-04-y:checked) .btn-04__mo{ opacity:0 }
.btn-04__card:has(#btn-04-y:checked) .btn-04__yr{ opacity:1 }Techniques used: hidden radios + label track · :has() state projection across the whole card · translate-based sliding thumb · opacity cross-fade for price swap · :focus-visible ring · prefers-reduced-motion guard
Make it yours
- Accent + thumb color read from one
--accenttoken. - Discount amount is plain text in the badge — set it to your real annual saving.
- Thumb slide speed = the
.btn-04__thumbtransition duration. - Add a third option (e.g. Quarterly) by adding a radio + label and widening the track grid to 3 columns.
Gotchas — read before shipping
- Keep the inputs as real radios, not divs — you get arrow-key selection, form submission and "selected" announcements for free.
- The thumb must be a sibling of the labels inside a
position:relativetrack, or the translate math drifts. - Announce the price change: put
aria-live=politeon the price region so screen readers hear the new amount when the period flips. - :has() is Baseline 2023; if you must support older engines, a 4-line JS fallback toggling a class keeps it working.

:has() selector is Baseline Newly Available (2023). Everywhere modern; older browsers can be covered with a tiny class-toggle shim.
