## Anatomy

Parts in bold are required.

`data-scope="input-group"`: **`root`** · `item`

## 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-input-group>` |
| Vue components | `XhInputGroupItem` `XhInputGroupRoot` |
| State machine | None: `connect` computes attributes from props directly |
| Skin | `@xihan-ui/styles/input-group.css` |

### Props

| Prop | Type | Required |
| --- | --- | --- |
| `size` | `Size` |  |
| `variant` | `ControlVariant` |  |

### connect API

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

| Member | Type |
| --- | --- |
| `getRootProps` | `() => T['element']` |
| `getItemProps` | `() => 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.

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

## Style reference

### Skin

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

### CSS variables

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