- Status: stable
- Group: display
- Page: https://www.digitaltableteur.com/design-system/components/value-card
- Contract: https://www.digitaltableteur.com/contracts/v1/ValueCard.contract.json

## When to use

Card for one value or principle (icon, title, one-liner) in about/culture grids.

## When not to use

- Do not use for content with a primary CTA; that is `ServiceCard` or `Card`.
- Do not mix `ValueCard` with `Card` in the same grid row; the rhythm desyncs.

## Look-alikes

- Card: Do not use for content with a primary CTA; that is `ServiceCard` or `Card`.
- ServiceCard: Do not use for content with a primary CTA; that is `ServiceCard` or `Card`.

## Props

| Prop | Type | Default | Description | Required |
| --- | --- | --- | --- | --- |
| `icon` | `ReactNode` | none | Decorative icon element. Its wrapper is aria-hidden, so the title carries the announcement. | Yes |
| `title` | `string` | none | Card title. | Yes |
| `description` | `string` | none | Card description. | Yes |
| `iconClassName` | `string` | none | Optional className for the icon wrapper. | No |
| `variant` | `"default" \| "bordered" \| "elevated"` | `default` | Card variant. | No |
| `href` | `string` | none | Destination. The title becomes a link whose hit area covers the whole card, with the card's hover and focus ring. Without it the card is static and has no hover, so it never looks clickable. | No |
| `className` | `string` | none | Custom className. | No |

## Variants

- Available variants: `default`, `elevated`, `bordered` (default `default`).

## Invalid combinations

## Rules

Every item under When not to use is a MUST NOT. MUST and SHOULD follow RFC 2119.

| Level | Rule | How it is checked |
| --- | --- | --- |
| MUST | ARIA: Renders an `<article>` (role=article, a document-structure role, not a region landmark) with the title as an h3. | Not yet verified: no evidence record. WCAG 4.1.2. |
| MUST | ARIA: ValueCard wraps the icon slot in an aria-hidden container, so even a labelled Icon or a text glyph passed by a caller is not announced; the title carries the announcement. | Not yet verified: no evidence record. WCAG 4.1.2. |
| MUST | Required stories produce no axe violations at the configured severity. | Automated by `npm run test:stories:matrix:ci`. WCAG 2.5.8. |
| MUST | The accessibility tree (role, name, state) matches the committed snapshot for every required story. | Automated by `npm run test:stories:matrix:ci`. WCAG 1.3.1, 4.1.2. |
| MUST | The component remains legible and operable under a real browser forced-colors: active pass. | Automated by `npm run test:stories:hc`. |
| MUST | A human completed an end-to-end accessibility review of this component. | Manual review, last on 2026-11-04. |
