Netscape Composer. Serious PTSD kicking in.

I'd do the Codecademt exercises, then pick up the Pragzprog book on HtML5/CSS3 if you were looking to start. Also, go through the official specs.

Wow, I'm horrid at typing on my phone sometimes.

What I meant was Codecademy: http://www.codecademy.com/ And the Pragmatic Programmer's Book on HTML5 and CSS3: http://pragprog.com/book/bhh5/html5-and-css3

Official Specs: http://www.w3.org/
