  Cameron takes us through the development of his current site design. Good job articulating his urlLink internal thought process . urlLink Jason and half the frickin' internet discuss CSS, XHTML and standards . Again! This one is a good intro to the whole topic though and be very relevant to people considering trading in their tried and true old web development techniques for new ones. urlLink Tomas Jogin totally geeks out on heading hierarchy (title, h1, h2, etc) and document outline. urlLink Dave Shea jumps in . Reading this thread made me feel a lot like Jason does in urlLink his post above this one . :P Some great code for urlLink lightweight, accessible CSS-based dropdown menus from Son of Suckerfish.
