Comment Intro to XHTML (Score 4, Informative) 39
No problem at all to start people off on XHTML instead of HTML. For an entry level, beginner's course which teaches correct, valid, accessible XHTML which will then link to a CSS stylesheet look at my Intro to XHTML. This includes how to correctly structure information rather than just format it. Includes MP3 files and video. It's free.
