# Transformer Variant Group
|
||||
|
||||
Enables shorthand syntax for grouping utilities with common prefixes.
|
||||
|
||||
## Installation
|
||||
|
||||
```ts
|
||||
import { defineConfig, transformerVariantGroup } from 'unocss'
|
||||
|
||||
export default defineConfig({
|
||||
transformers: [
|
||||
transformerVariantGroup(),
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
Group multiple utilities under one variant prefix using parentheses:
|
||||
|
||||
```html
|
||||
<!-- Before transformation -->
|
||||
<div class="hover:(bg-gray-400 font-medium) font-(light mono)" />
|
||||
|
||||
<!-- After transformation -->
|
||||
<div class="hover:bg-gray-400 hover:font-medium font-light font-mono" />
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
### Hover States
|
||||
|
||||
```html
|
||||
<button class="hover:(bg-blue-600 text-white scale-105)">
|
||||
Hover me
|
||||
</button>
|
||||
```
|
||||
|
||||
Expands to: `hover:bg-blue-600 hover:text-white hover:scale-105`
|
||||
|
||||
### Dark Mode
|
||||
|
||||
```html
|
||||
<div class="dark:(bg-gray-800 text-white)">
|
||||
Dark content
|
||||
</div>
|
||||
```
|
||||
|
||||
Expands to: `dark:bg-gray-800 dark:text-white`
|
||||
|
||||
### Responsive
|
||||
|
||||
```html
|
||||
<div class="md:(flex items-center gap-4)">
|
||||
Responsive flex
|
||||
</div>
|
||||
```
|
||||
|
||||
Expands to: `md:flex md:items-center md:gap-4`
|
||||
|
||||
### Nested Groups
|
||||
|
||||
```html
|
||||
<div class="lg:hover:(bg-blue-500 text-white)">
|
||||
Large screen hover
|
||||
</div>
|
||||
```
|
||||
|
||||
Expands to: `lg:hover:bg-blue-500 lg:hover:text-white`
|
||||
|
||||
### Multiple Prefixes
|
||||
|
||||
```html
|
||||
<div class="text-(sm gray-600) font-(medium mono)">
|
||||
Styled text
|
||||
</div>
|
||||
```
|
||||
|
||||
Expands to: `text-sm text-gray-600 font-medium font-mono`
|
||||
|
||||
## Key Points
|
||||
|
||||
- Use parentheses `()` to group utilities
|
||||
- The prefix applies to all utilities inside the group
|
||||
- Can be combined with any variant (hover, dark, responsive, etc.)
|
||||
- Nesting is supported
|
||||
- Works in class attributes and other extraction sources
