## Installation
```
npm install css-url-parser
```

## Usage
```javascript
var parseCssUrls = require('css-url-parser');

var css = '@import "a.css"; .image { background-image: url(images/img.png); }';
var cssUrls = parseCssUrls(css);

console.log(cssUrls);   // [ 'a.css', 'images/img.png' ]
```

It ignores duplicated urls and base64 encoded resources.
If no urls found empty array will be returned.
