I'm trying to figure out how to create a div that overlays the page, staying in one place when the page scrolls, such as used in this article: Top 5 Botched PC Game Launches. (You will see a bar at the top that doesn't move, with the logo, where gamers call home).
I'm not even sure what the correct terminology is - it's probably not overlay :) But whatever it is, it appears to be done with CSS only, as it shows up when Javascript is disabled.
