How to Develop with CSS
 
(notes from the author)
 
This document does not rely on advanced CSS3 selectors (which are neither standard nor well-supported in browsers as of this writing). This document doesn't even talk about certain advanced CSS2 selectors...which are standard but happen to not be supported in the world's most popular browser.

This document is not a guide on how to format your CSS or HTML, and does not attempt to instruct you on how to use CSS to achieve cutting edge layouts. (For examples of some layout techniques, see Glish/CSS, FormDL, and CSS/Edge.)

This document assumes you know the basics about CSS1 (what a selector is, what a compound selector is versus a descendant selector, how values inherit, etc.), and provides a series of guidelines to help you develop with CSS properly.
