Parses CSS media query expressions.

## Installation

Install via npm:

```shell
$ npm install css-mq-parser
```

## Usage

This package exports one function, which can parse CSS media query expressions and return an AST.
The parser tolerates several known CSS media query browser hacks, but will throw a `SyntaxError` if the media query expression is severely malformed.
Note that this module implements a lax/liberal/non-validating parser; even modulo browser hacks, the fact that it parses a given expression successfully does not guarantee that the expression is valid per the relevant CSS specifications.

```javascript
var parseMediaQuery = require('css-mq-parser');
var ast = parseMediaQuery('screen and (min-width: 48em)');
```

The `ast` variable will have the following payload:

```json
[
    {
        "inverse": false,
        "preTypeHack": "",
        "type": "screen",
        "postTypeHack": "",
        "expressions": [
            {
                "modifier": "min",
                "feature": "width",
                "value": "48em"
            }
        ]
    }
]
```
