Starting caveat - while I used custom layouts on LJ, and occasionally tweaked some, I never wrote any CSS overrides from scratch, mostly because I remember when S2 went live and I went 'LAYERS? A PROGRAMMING LANGUAGE? WHAT IS THIS SHIT I'M NEVER MAKING MY OWN LAYOUTS AGAIN'. So while I can answer a lot of questions about how DW does things, I don't know the answer to 'what's the equivalent of this LJ element in DW?'. I also do not know the answer to 'I broke my imported core1 layout, how do I fix it.' I'm also assuming you know CSS and HTML, but not necessarily any other programming language.

( Onward! )
