# Layers and Preflights
|
|
|
|
Control CSS output order and inject global CSS.
|
|
|
|
## Layers
|
|
|
|
Set layer on rules:
|
|
|
|
```ts
|
|
rules: [
|
|
[/^m-(\d)$/, ([, d]) => ({ margin: `${d / 4}rem` }), { layer: 'utilities' }],
|
|
['btn', { padding: '4px' }], // default layer
|
|
]
|
|
```
|
|
|
|
### Layer Ordering
|
|
|
|
```ts
|
|
layers: {
|
|
'components': -1,
|
|
'default': 1,
|
|
'utilities': 2,
|
|
}
|
|
```
|
|
|
|
### Import Layers Separately
|
|
|
|
```ts
|
|
import 'uno:components.css'
|
|
import 'uno.css'
|
|
import './my-custom.css'
|
|
import 'uno:utilities.css'
|
|
```
|
|
|
|
### CSS Cascade Layers
|
|
|
|
```ts
|
|
outputToCssLayers: true
|
|
|
|
// Or with custom names
|
|
outputToCssLayers: {
|
|
cssLayerName: (layer) => {
|
|
if (layer === 'default') return 'utilities'
|
|
if (layer === 'shortcuts') return 'utilities.shortcuts'
|
|
}
|
|
}
|
|
```
|
|
|
|
## Layer Variants
|
|
|
|
```html
|
|
<!-- UnoCSS layer -->
|
|
<p class="uno-layer-my-layer:text-xl">
|
|
|
|
<!-- CSS @layer -->
|
|
<p class="layer-my-layer:text-xl">
|
|
```
|
|
|
|
## Preflights
|
|
|
|
Inject raw CSS globally:
|
|
|
|
```ts
|
|
preflights: [
|
|
{
|
|
getCSS: ({ theme }) => `
|
|
* {
|
|
color: ${theme.colors.gray?.[700] ?? '#333'};
|
|
margin: 0;
|
|
}
|
|
`,
|
|
},
|
|
]
|
|
```
|
|
|
|
With layer:
|
|
|
|
```ts
|
|
preflights: [
|
|
{
|
|
layer: 'base',
|
|
getCSS: () => `html { font-family: system-ui; }`,
|
|
},
|
|
]
|
|
```
|
|
|
|
