[PostCSS Container Rule Prelude List] lets you declare a list of container queries in a single `@container` rule following the [CSS Conditional 5 Specification].

```css
@container card (inline-size > 30em), style(--responsive: true) {
	a {
		color: red;
	}
}

/* becomes */

@container card (inline-size > 30em) {
	a {
		color: red;
	}
}
@container style(--responsive: true) {
	a {
		color: red;
	}
}
```

## Usage

Add [PostCSS Container Rule Prelude List] to your project:

```bash
npm install postcss @csstools/postcss-container-rule-prelude-list --save-dev
```

Use it as a [PostCSS] plugin:

```js
const postcss = require('postcss');
const postcssContainerRulePreludeList = require('@csstools/postcss-container-rule-prelude-list');

postcss([
	postcssContainerRulePreludeList(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);
```



## Options

### preserve

The `preserve` option determines whether the original notation
is preserved. By default, it is not preserved.

```js
postcssContainerRulePreludeList({ preserve: true })
```

```css
@container card (inline-size > 30em), style(--responsive: true) {
	a {
		color: red;
	}
}

/* becomes */

@container card (inline-size > 30em) {
	a {
		color: red;
	}
}
@container style(--responsive: true) {
	a {
		color: red;
	}
}
@container card (inline-size > 30em), style(--responsive: true) {
	a {
		color: red;
	}
}
```
