I read this quite a while back and went looking for it: CSS Drop Shadows: A List Apart
Add to this thought in the back of my mind: the CSS trick I learned for wrapping text and left-justifying text from “Learning Moveable Type”
Could they be combined?
Also, that’s a sweet trick for setting off a quote block… it could be centered rather than left-justified and Bob’s yer uncle. Must play with that later.
