An Introduction to the Compass CSS Framework
Web developers often wish it was someone else's job to maintain the CSS files associated with a website, as they can get large and tedious to follow. The Compass CSS framework can simplify things, making it easier to create and maintain the CSS for a website.
The open source Compass CSS framework provides a set of tools and utilities that enable a developer to create CSS that is cross-browser, and gracefully degradable. It's a complete CSS authoring environment that includes helper functions for colors, fonts, images and math calculations.
Compass was written in Ruby, and requires a working installation of Ruby and Ruby Gems, and it also uses SASS and Blueprint, so you will need to verify that you have them all up and running before you try to use Compass.
