Digg/Stumbleupon Bar

I'm looking to see if it's possible to implement a "bar" like you guys have, along with Digg, Stumble upon and other websites.

I have no idea what it's even called - frameset, iframe of sorts but I can't even think of a prop开发者_如何学编程er title to search google..

Can you help?

You can have a normal div tag (or whatever tag you want to use) with CSS position property set to 'fixed'. Then the element can be positioned where ever you want and scrolling the page doesn't affect the position.
