# DimSiblings

> Wraps a group of cards, links, or list items so hovering or keyboard-focusing one dims (or blurs) every other one — a pure CSS :has() affordance with zero pointer-tracking JavaScript.

- Package: `fancy-ui-vue` (Vue 3.5+ + Tailwind CSS v4)
- Category: Effects
- Tags: hover, focus, dim, blur, has-selector, css-only, micro-interaction
- Types: `DimSiblingsProps`
- Docs: https://fancy-ui.rama.app/docs/components/dim-siblings
- Source: https://github.com/RamaHerbin/fancy-ui/tree/main/vue/src/components/dim-siblings

## Import

```vue
<script setup lang="ts">
import { DimSiblings } 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 |
| --- | --- | --- | --- |
| `effect` | `"dim" \| "blur" \| "both"` | `"dim"` | Which visual property the non-active siblings lose |
| `opacity` | `number` | `0.4` | Opacity the non-active siblings settle to — a floor, not zero |
| `blur` | `number` | `2` | Blur radius in px, applied only when effect includes blur |
| `duration` | `number` | `150` | Transition duration in ms for the opacity/blur change |
| `as` | `keyof HTMLElementTagNameMap` | `"div"` | The rendered root element — "ul"/"ol" for a list whose CSS list semantics need to survive the wrapper |
| `class` | `string` | — | Additional CSS classes |
| `ref` | `HTMLElement \| null` | `null` | Bindable reference to the root element |

## Slots

| Slot | Description |
| --- | --- |
| `#default` (Svelte `children`) | The sibling group — every direct child participates |

## 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/dim-siblings.md.
