After some searching, I found a css minification library for PHP, minify
It was very easy to modify it so that It could be used in our CodeIgniter applications like any other libraries. All I did was wrap the main minification function in Codeigniter specific code. I modelled the interaction on the image library, as I guess that’s what most people are used to.
How to use

Will output the following stylesheet tag:
You can get it from GitHub. Don’t forget to fork it if you think you can make it better!
