# CSSOM
|
||
|
||
CSSOM.js is a CSS parser written in pure JavaScript. It is also a partial implementation of [CSS Object Model](http://dev.w3.org/csswg/cssom/).
|
||
|
||
CSSOM.parse("body {color: black}")
|
||
-> {
|
||
cssRules: [
|
||
{
|
||
selectorText: "body",
|
||
style: {
|
||
0: "color",
|
||
color: "black",
|
||
length: 1
|
||
}
|
||
}
|
||
]
|
||
}
|
||
|
||
|
||
## [Parser demo](http://nv.github.com/CSSOM/docs/parse.html)
|
||
|
||
Works well in Google Chrome 6+, Safari 5+, Firefox 3.6+, Opera 10.63+.
|
||
Doesn't work in IE < 9 because of unsupported getters/setters.
|
||
|
||
To use CSSOM.js in the browser you might want to build a one-file version that exposes a single `CSSOM` global variable:
|
||
|
||
➤ git clone https://github.com/NV/CSSOM.git
|
||
➤ cd CSSOM
|
||
➤ node build.js
|
||
build/CSSOM.js is done
|
||
|
||
To use it with Node.js or any other CommonJS loader:
|
||
|
||
➤ npm install cssom
|
||
|
||
## Don’t use it if...
|
||
|
||
You parse CSS to mungle, minify or reformat code like this:
|
||
|
||
```css
|
||
div {
|
||
background: gray;
|
||
background: linear-gradient(to bottom, white 0%, black 100%);
|
||
}
|
||
```
|
||
|
||
This pattern is often used to give browsers that don’t understand linear gradients a fallback solution (e.g. gray color in the example).
|
||
In CSSOM, `background: gray` [gets overwritten](http://nv.github.io/CSSOM/docs/parse.html#css=div%20%7B%0A%20%20%20%20%20%20background%3A%20gray%3B%0A%20%20%20%20background%3A%20linear-gradient(to%20bottom%2C%20white%200%25%2C%20black%20100%25)%3B%0A%7D).
|
||
It does **NOT** get preserved.
|
||
|
||
If you do CSS mungling, minification, or image inlining, considere using one of the following:
|
||
|
||
* [postcss](https://github.com/postcss/postcss)
|
||
* [reworkcss/css](https://github.com/reworkcss/css)
|
||
* [csso](https://github.com/css/csso)
|
||
* [mensch](https://github.com/brettstimmerman/mensch)
|
||
|
||
|
||
## [Tests](http://nv.github.com/CSSOM/spec/)
|
||
|
||
To run tests locally:
|
||
|
||
➤ git submodule init
|
||
➤ git submodule update
