# @tailwindcss/nesting
This is a PostCSS plugin that wraps [postcss-nested](https://github.com/postcss/postcss-nested) or [postcss-nesting](https://github.com/jonathantneal/postcss-nesting) and acts as a compatibility layer to make sure your nesting plugin of choice properly understands custom syntax like `@apply` and `@screen`.
To use it, install it via npm:
```shell
npm install @tailwindcss/nesting
```
Then add it to your PostCSS configuration, somewhere before Tailwind itself:
```js
// postcss.config.js
module.exports = {
plugins: [
require('postcss-import'),
require('@tailwindcss/nesting'),
require('tailwindcss'),
require('autoprefixer'),
]
}
```
By default, it uses the [postcss-nested](https://github.com/postcss/postcss-nested) plugin under the hood, which uses a Sass-like syntax and is the plugin that powers nesting support in the [Tailwind CSS plugin API](https://tailwindcss.com/docs/plugins#css-in-js-syntax).
If you'd rather use [postcss-nesting](https://github.com/jonathantneal/postcss-nesting) (which is based on the work-in-progress [CSS Nesting](https://drafts.csswg.org/css-nesting-1/) specification), first install the plugin alongside `@tailwindcss/nesting`:
```shell
npm install @tailwindcss/nesting postcss-nesting
```
Then pass the plugin itself as an argument to `@tailwindcss/nesting` in your PostCSS configuration:
```js
// postcss.config.js
module.exports = {
plugins: [
require('postcss-import'),
require('@tailwindcss/nesting')(require('postcss-nesting')),
require('tailwindcss'),
require('autoprefixer'),
]
}
```
This can also be helpful if for whatever reason you need to use a very specific version of `postcss-nested` and want to override the version we bundle with `@tailwindcss/nesting` itself.
