Custom Radio Button Cards (Selectable Cards)

The most-requested radio pattern in modern checkout and onboarding UIs: full selectable cards that act as radio buttons. Each shipping option is a real <input type="radio"> wrapped in a card label — click anywhere on the card to select it, and the chosen card lifts, tints and reveals a springy check dot. Pure CSS via :has(), no JavaScript.

## JavaScript
```js
/* No JavaScript — the whole card is a <label> around a hidden radio; :has(input:checked) styles the parent card, and :has(input:focus-visible) re-projects the keyboard focus ring onto the card. */
```

How this works

Each card is a <label> containing a visually-hidden radio input, so the entire card surface is the hit target. The modern :has() selector styles the parent card from its child's state: .card:has(input:checked) swaps the border to the accent, lifts the card with transform:translateY and springs the corner dot in with an overshoot cubic-bezier.

Accessibility: the group lives in a <fieldset> with a <legend>, so assistive tech announces the question before the options. Because the input is real (hidden with opacity, not display:none), arrow keys still move selection between cards and :focus-visible is re-projected onto the card as a visible outline — no role="radiogroup" re-implementation needed.

Make it yours

  • Recolour the whole demo via the single --accent custom property.
  • Change card width in .crb-01a__card — the flex row wraps automatically on mobile.
  • Tune the selection spring via the dot's cubic-bezier overshoot.
  • Move the check dot, or replace it with a corner ribbon, without touching the selection logic.

Gotchas — read before shipping

  • Hide the input with opacity:0, never display:none — display:none removes it from the tab order and breaks arrow-key navigation.
  • Put :focus-visible styling on the card, not the invisible input, or keyboard users get no visible focus at all.
  • Keep the lift on transform so nothing reflows (CLS 0).

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

:has() is the only modern dependency and is Baseline since 2023. Without it the cards stay fully functional radio buttons — only the checked highlight is lost.
