Here’s a list of some good links. A lot of these are great for beginners –they are places I relied on many years ago when I was first starting in Web Design.
http://www.cdilearn.com/cmat/html/crossref.html - HTML tags. Anyone who works in web design should know basic HTML –there’s no excuse not to, no matter how shiny and full featured your web page editor might be.
http://www.ascii.cl/htmlcodes.htm – ASCII codes. You’ll need these to go along with your HTML.
http://www.tizag.com/ – They have some excellent beginner’s tutorials for php, asp, mysql and other web essentials.
Those three are pages I’ve used for years –now here’s one I just found today: a clear concise cheatsheet for .htaccess regex (regular expressions redirects).
