I got to thinking about font (typeface) selection today. A site I did for work came with this professsionally done style guide that detailed colour selection, font selection, spacing, etc. It's the first time I'd seen anything like that but I have to admit, what they'd chosen did look good.
Now I've previously read about colour theory so I know about complementary colours and choosing colours schemes with say 1, 2 or 3 different colours. So I'm fine with that side of things for my pet project anyway.
But I haven't really seen anything about typeface selection in the Web context. I found some discussions on fonts for printing where you had the option of downloading and including custom fonts. That's not an option on the Web. You're limited to what browsers (or, rather, operating systems) support. I'd be interested in reading something about what IE and Firefox support on Windows and Mac (sorry, Linux is too marginal to be a consideration for anything other than CSS font-family fallback) and what those fonts convey: whether they're serious, formal, casual, inviting, etc.
Anyone know anything like this?
