css compressor and factorization

Question

I'm working with a friend on a project with a huge CSS file. There is a lot of duplication like:

h1 {
  color : black;
}

h1 {
  color : blue;
  width: 30px;
}

The first h1 can be removed, because it will never be used, because fully rewrited by the second. (because it is in the same CSS file)

I would know if it exists a tool that factorizes (and compress) this kind of stuff. To only have at the end:

h1 {color:blue;width:30px}

PS: If it can be an online tool, it will be perfect!

There's a nice one in ruby: http://zmoazeni.github.io/csscss

In node.js: https://github.com/rbtech/css-purge

Both are very easy to use from command line.

This is also a nice once: http://cssmerge.sourceforge.net

And a plugin for Firefox: https://addons.mozilla.org/en-us/firefox/addon/css-usage

If you are using Firefox, you can use this addon which will help you achieve it.

https://addons.mozilla.org/en-us/firefox/addon/css-usage/

It creates a new css which tells you only used rules and sideline unused one. It also lets you export that css.
