[PostCSS Nesting] lets you nest style rules inside each other, following the
[CSS Nesting] specification.

```pcss
a, b {
  color: red;

  & c, & d {
    color: white;
  }
}

/* becomes */

a, b {
  color: red;
}

a c, a d, b c, b d {
  color: white;
}
```

**NOTICE**: In a future version of this project, nesting at-rules like `@media`
may be deprecated, as they are not part of the nesting proposal. In a comment,
a CSSWG member expressed interest in handling nested `@media` while handling
selector nesting. So deprecating nested at-rules has been temporarily delayed.

## Usage

Or use it as a [PostCSS] plugin:

```js
import postcss from 'postcss';
