I had to learn HTML for a game that I played on and then continued with GJ and IJ. I learned enough by age 12 to be asked to make websites for people. The same with graphic design. If you want to know how to do things, you learn. So hopefully people will use it not just as a resource to copy/paste code from but as a springboard into bigger and better things.
The amusing part was that I knew 95% of the codes off the top of my head. I stole a few from FC and etc to make sure I was listing everything necessary.
