I'm not the type of designer that likes complicated and frilly designs; in fact, I'm not really a designer at all, but I like to think I can design. I have given myself a challenge:
Create a copy of this site that only uses CSS to control whitespace, not color or size.
We'll see how it goes and what I come up with. Once that's done, and I'm satisfied, I'll play with color, but in a very minimal way, of course.
