I wasn't sure where to put this, considering it relates to more than one topic... Anyway, I've been out of web development for like a year now, and now I come back to find all this stuff like HTML5 and CSS3 and everything. I'm a youngen, and technology still moves too fast for me . So, what is actually necessary to know? I don't really have any implementations, but I always like to know a good bit just in case . Any suggestions?
