I thought I’d quickly share a few sites that I’ve either found personally useful or, given where I am now, wish existed when I was picking the trade up.

Picking it Up

htmldog – Learn, love, and live this site. Honestly, this is covers most of the html you’ll ever need to know these days, it explains the semantics, and it even includes a CSS primer.

w3schools – Has CSS/(X)HTML sections amongst others. It has decent working examples but think of it mainly as a reference guide.
