Learning

Give me your best references/websites to learn JavaScript/AJAX/CSS.
GO!

I already know most basic stuff in CSS but I feel like it isn't enough to call my knowledge about it "decent".

the back-end is the part that responds to javascript requests with some JSON. it can be written in whatever framework you want, but LISP (and now racket) has long been industry standard here at /prog/.

i strongly recommend you create your next website without generating any HTML on the server side, rather use AJAX to load the content from your racket back-end.
