## About

A [PostCSS](https://github.com/postcss/postcss) plugin to prettify output. Requires at least Node.js v0.12. Should likely be included towards the end of a PostCSS plugin chain, if that's your jam.

**Features**
- line breaks between top-level rules and comments
- smart spacing around rules and declarations
- indenting with 2 spaces
- one selector per line

**Example Input**
```css
.foo, .bar {
    background: red;
}
@media only screen and (min-width:600px){.baz{background:blue;}}
```

**Example Output**
```css
.foo,
.bar {
  background: red;
}

@media only screen and (min-width: 600px) {
  .baz {
    background: blue;
  }
}
```

## Installation

**From a terminal**

```sh
npm install --save-dev postcss-prettify
```

## Usage

**As a PostCSS Plugin**
```js
postcss([
  require('postcss-prettify')
])
```

Check the [PostCSS docs](https://github.com/postcss/postcss#usage) for your chosen implementation.

**Standalone**

`postcss-prettify` also exposes a standalone [PostCSS processor instance](https://github.com/postcss/postcss/blob/master/docs/api.md#processorprocesscss-opts) as `prettify.process(css)`:

```js
var fs = require('mz/fs')
var prettify = require('postcss-prettify')

fs.readFile('src/style.css', 'utf8')
  .then(data => prettify.process(data))
  .then(res => fs.writeFile('dist/style.css', res.css))
  .catch(err => console.err(err.stack))
```
