Abstract:

In this article I will propose a new method for organizing CSS that better maps to how popular web application frameworks are built; and I’ll also provide some helpful code to make this easy to accomplish. The examples I use are based on Ruby on Rails, but the concepts should be easily transferrable to other MVC frameworks.
