A little knowledge is a dangerous thing. I used a lot of CSS on my website that I just learned on the fly. But that meant a lot of jacked up code that was not compliant with XHTML standards. So be it. I willfully ignored my instructor's mantra: "Just because it looks okay on the page doesn't mean it's right."
I won't be signing up for the Intermediate Web Design class. Not in the near future, anyway. If I'm going to be hunched over my computer, I'd rather be blogging.
