## Anatomy

Parts in bold are required.

`data-scope="empty-state"`: **`root`** · `media` · `indicator` · `title` · `description` · `action`

## 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-empty-state>` |
| Vue components | `XhEmptyStateAction` `XhEmptyStateDescription` `XhEmptyStateIndicator` `XhEmptyStateMedia` `XhEmptyStateRoot` `XhEmptyStateTitle` |
| State machine | `emptyStateMachine` |
| Skin | `@xihan-ui/styles/empty-state.css` |

### Props

| Prop | Type | Required |
| --- | --- | --- |
| `live` | `EmptyStateLive` |  |
| `size` | `Size` |  |
| `status` | `EmptyStateStatus` |  |
| `tone` | `Tone` |  |

### State

The following names are internal to the state machine.

**States**: `idle`

**Events**: `APPEARANCE.RELEASE`

### connect API

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

| Member | Type |
| --- | --- |
| `live` | `EmptyStateLive` |
| `getRootProps` | `() => T['element']` |
| `getMediaProps` | `() => T['element']` |
| `getIndicatorProps` | `() => T['element']` |
| `getTitleProps` | `() => T['element']` |
| `getDescriptionProps` | `() => T['element']` |
| `getActionProps` | `() => T['element']` |

## Accessibility

### Keyboard

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

No keyboard interaction: the component takes no focus, or focus behavior comes entirely from native elements.

### ARIA

These attributes are produced by `connect`.

| Part | Attribute | Value |
| --- | --- | --- |
| `root` | `role` | undefined \| 'status' |
| `media` | `aria-hidden` | 'true' |
| `indicator` | `aria-hidden` | 'true' |

## Style reference

### Skin

`@xihan-ui/styles/empty-state.css` is written against `[data-scope="empty-state"][data-part="root"]` part selectors; the published build uses the mount class `.xh-scope-empty-state` 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.

### Data attributes

Produced by `connect`; valueless attributes are omitted while their condition does not hold.

| Part | Attribute | Value |
| --- | --- | --- |
| `root` | `data-size` | props.size |
| `root` | `data-status` | props.status |
| `root` | `data-tone` | props.tone |
| `media` | `data-instant` | '' (present only while the condition holds) |
| `indicator` | `data-instant` | '' (present only while the condition holds) |
| `title` | `data-instant` | '' (present only while the condition holds) |
| `description` | `data-instant` | '' (present only while the condition holds) |
| `action` | `data-instant` | '' (present only while the condition holds) |

### CSS variables
