## Anatomy

Parts in bold are required.

`data-scope="card"`: **`root`** · `header` · `title` · `trigger` · `description` · `content` · `footer`

## API reference

Descriptions of individual props, events and slots are written in Chinese and appear on the Chinese page.

### Artifacts

| Layer | Value |
| --- | --- |
| Custom element | `<xh-card>` |
| Vue components | `XhCardContent` `XhCardDescription` `XhCardFooter` `XhCardHeader` `XhCardRoot` `XhCardTitle` `XhCardTrigger` |
| State machine | None: `connect` computes attributes from props directly |
| Skin | `@xihan-ui/styles/card.css` |

### Props

| Prop | Type | Required |
| --- | --- | --- |
| `interactive` | `boolean` |  |
| `variant` | `ControlVariant` |  |

### Slots

Only slots with a payload are listed.

| Vue component | Slot | Payload |
| --- | --- | --- |
| `XhCardRoot` | `default` | — |
| `XhCardRoot` | `title` | — |
| `XhCardRoot` | `description` | — |
| `XhCardRoot` | `content` | — |
| `XhCardRoot` | `footer` | — |

### React adapter props

Only the props each component declares itself: DOM attributes inherited from `ComponentPropsWithRef` are left out, and root props already listed in the Props table are not repeated. The Vue counterpart is the slot table above.

| React component | Prop | Type | Required |
| --- | --- | --- | --- |
| `XhCardRoot` | `title` | `ReactNode` |  |
| `XhCardRoot` | `description` | `ReactNode` |  |
| `XhCardRoot` | `content` | `ReactNode` |  |
| `XhCardRoot` | `footer` | `ReactNode` |  |

### connect API

`getXxxProps()` returns the host attributes of the matching part.

| Member | Type |
| --- | --- |
| `getRootProps` | `() => T['element']` |
| `getHeaderProps` | `() => T['element']` |
| `getTitleProps` | `() => T['element']` |
| `getTriggerProps` | `() => T['element']` |
| `getDescriptionProps` | `() => T['element']` |
| `getContentProps` | `() => T['element']` |
| `getFooterProps` | `() => T['element']` |

## Accessibility

### Keyboard

Specification: [W3C APG](https://www.w3.org/WAI/ARIA/apg/). Each row is a stable behavior id that the conformance tests cover; the conditions and effects are described on the Chinese page.

| Keys | Behavior |
| --- | --- |
| `Enter` / `Space` | `card.kbd.activate` |

## Style reference

### Skin

`@xihan-ui/styles/card.css` is written against `[data-scope="card"][data-part="root"]` part selectors; the published build uses the mount class `.xh-scope-card` in place of data-scope (same specificity) and sits in the `xihan.components` layer. Put overrides in `xihan.overrides`; the part selectors work as usual.

### CSS variables

The public override slots, generated from what the standalone skin actually consumes.
