"Liquid HTML" Design

One of the designers on my project has been buying $5 web 2.0 terms from shady characters in back alleys. I know this is a real model/concept, and therefore; not something you can ask a generic question about. So all I'm after is some resources. Rules, ideas, concepts, thoughts, models, tests - whatever.

If you got links, post'em. If you got opinions, post'em also. If you've been burned trying this, by all means fill me in.

For those not familiar with the term, it's using HTML and CSS to support multiple resolutions. Things grow, things shrink, things look like crap - but not as crappy if they were statically sized and positioned.

Like most $5 Web 2.0 terms from shady characters in back alleys, it's a case of giving an impressive-sounding, marketable name to something that people have already been doing for centuries. Well, not centuries, but you get my drift.

All "liquid" design entails is simply using margins/padding instead of fixed height/width properties. And em units so that the design scales with the font size. That's about it, really. Just avoid any hard coded dimensions and the "liquid" effect comes naturally.
