# Skeleton

> Placeholder bones — a block, one or more text lines, or a circular avatar — with a phase-synced shimmer sweep or opacity pulse, that swaps to real content once loading finishes while keeping aria-busy semantics correct throughout.

## Import

```vue
<script setup lang="ts">
import { Skeleton } from 'fancy-ui-vue';
</script>
```

Setup (once per project): `npm install fancy-ui-vue`, then put these lines in your main CSS file (the stylesheet imports go right after `@import "tailwindcss";`):

```css
@import "tailwindcss";
@import "fancy-ui-vue/tailwind.css";
@import "fancy-ui-vue/styles.css";
```

The names below are the ones to write in a Vue template; when one differs from the Svelte name, the Svelte name follows in parentheses. Snippets become named slots (`#default` is the default snippet), a prop the Vue port declares as a model is a `v-model:<name>` (except `ref`, exposed via `defineExpose({ ref })`: put a template ref on the component and read `.ref`) and callbacks are listeners (`onclick` is `@click`). Every component sets `inheritAttrs: false`: `class` is a declared prop, merged where the Svelte component applies it (not always the root element), and only when the props table below lists it; other attributes do not fall through unless the package README lists the component as forwarding native attributes.

## Props

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `variant` | `"rect" \| "text" \| "circle"` | `"rect"` | Bone shape: a block, one or more text lines, or a circular avatar |
| `lines` | `number` | `1` | Number of text lines to render; only read when variant is "text". The last line renders at 60% width so a paragraph placeholder doesn't read as a perfect rectangle |
| `animation` | `"shimmer" \| "pulse" \| "none"` | `"shimmer"` | Shimmer sweep, opacity pulse, or a static muted bone (still a valid loading cue on its own) |
| `loading` | `boolean` | `true` | Whether the placeholder is currently showing. In wrapping mode (children supplied) drives the swap to real content; in standalone mode drives whether anything renders at all |
| `label` | `string` | `"Loading"` | The one screen-reader announcement. Pass "" to silence it entirely |
| `class` | `string` | — | Additional CSS classes; also the sizing hook, since rect/text bones have no intrinsic size |
| `ref` | `HTMLDivElement \| null` | `null` | Bindable reference to the root element; null whenever nothing is rendered |

## Slots

| Slot | Description |
| --- | --- |
| `#default` (Svelte `children`) | Real content to reveal once loading is false. Its mere presence (not its value) switches Skeleton from standalone to wrapping mode |

## Example

No Vue example is published for this component yet: start from the import above and the props table. The full examples are Svelte-only, on https://fancy-ui.rama.app/docs/components/skeleton.md.
