I were looking for a CSS Framework to help me built website, when I struck with Compass.
Now, while I understand what a CSS Framework is, I don't understand what's a CSS Authoring Framework.
Expecially, I don't understand if it "replaces" a CSS Framework (like blueprint) or you should use it with a CSS Framework.
I'm building a website using Ruby On Rails, and I use SASS but no CSS Frameworks at the moment. If anyone can point me in right direction after answering the question, it will be really appreciated.
Edit 1: Also, which is the difference between a CSS Framework and a CSS Authoring Framework
A CSS Framework is (in most cases) a fixed set of basic CSS definitions. f.e. it brings definitions for some classes which make a basic div-based HTML-layout usable for different screen-widths. (aka liquid layout)
A CSS Authoring Framework (in meaning of Compass) brings no fixed set of CSS definitions. In opposite to a standard CSS Framework, it helps to write CSS rules with various helpers - but you have to write almost every CSS definition by your own. Some examples for helpers: Compass helps you to fix some common browser issues (IE floats ..). And you can create CSS sprites from existing images with all the CSS definitions on the fly.
You can write your own CSS Framework with the help of a CSS Authoring Framework, or you can simple build on top of a existing CSS Framework.
