# CSSTree
CSS parsing into javascript object.
### Installation
```bash
$ npm install csstree
```
CSSTree may also be run in a browser enviornment.
```html
<script type='text/javascript' src='CSSTree.js'></script>
```
### Usage
```js
var instance = new CSSTree( css );
// CSS Tree
console.log( instance.branches );
```
### Example
```js
var instance = new CSSTree( "html body { background: red; margin: 10px 5px; }" );
console.log( instance.branches );
```
Will give an object format of the following:
```js
{
selector: 'html body',
parts: [
'html',
'body'
],
rules: [
{
property: 'background',
value: 'red',
parts: [
'red'
]
},
{
property: 'margin',
value: '10px 5px',
parts: [
'10px',
'5px'
]
}
]
}
```
### Position Objects
Every selector, rule, atrule and comment includes a 'Position' object which contains useful
information about that fragments section of the stylesheet. Comes in the following form:
```js
{
property: 'background',
value: 'red',
parts: [
'red'
],
position: {
range: {
start: 40,
end: 60,
length: 20
},
start: {
line: 2,
character: 2
},
end: {
line: 2,
character: 22
},
chunks: [
{
start: 40,
end: 60,
length: 20
}
]
}
}
```
* **range**: Contains the start and end positions of the fragment within the stylesheet
* **start**: Contains the starting line/character info of the fragment based on line breaks (\r\n|\r|\n)
* **end**: Contains the ending line/character info of the fragment based on line breaks (\r\n|\r|\n)
* **chunks**: When a comment exists between the start & end positions, chunks represents only the sections that belong to this position.
