# css-parse [](https://travis-ci.org/visionmedia/css-parse)
JavaScript CSS parser for nodejs and the browser.
## Installation
$ npm install css-parse
## Usage
````javascript
var parse = require('css-parse');
// CSS input string
var css = "body { \n background-color: #fff;\n }";
var output_obj = parse(css);
// Position and Source parameters
var output_obj_pos = parse(css, { position: true, source: 'file.css' });
// Print parsed object as CSS string
console.log(JSON.stringify(output_obj, null, 2));
````
## Example
css:
```css
body {
background: #eee;
color: #888;
}
```
parse tree:
```json
{
"type": "stylesheet",
"stylesheet": {
"rules": [
{
"type": "rule",
"selectors": [
"body"
],
"declarations": [
{
"type": "declaration",
"property": "background",
"value": "#eee"
},
{
"type": "declaration",
"property": "color",
"value": "#888"
}
]
}
]
}
}
```
parse tree with `.position` enabled:
```json
{
"type": "stylesheet",
"stylesheet": {
"rules": [
{
"type": "rule",
"selectors": [
"body"
],
"declarations": [
{
"type": "declaration",
"property": "background",
"value": "#eee",
"position": {
"start": {
"line": 3,
"column": 3
},
"end": {
"line": 3,
"column": 19
}
}
},
{
"type": "declaration",
"property": "color",
"value": "#888",
"position": {
"start": {
"line": 4,
"column": 3
},
"end": {
"line": 4,
"column": 14
}
}
}
],
"position": {
"start": {
"line": 2,
"column": 1
},
"end": {
"line": 5,
"column": 2
}
}
}
]
}
}
```
If you also pass in `source: 'path/to/original.css'`, that will be set
on `node.position.source`.
## Performance
