I recently stumbled upon this microsite from the Obama campaign:
http://www.barackobama.com/anniversary
Among the many cool features of this site is its dynamic header -- when you resize your browser window smaller, the "OBAMA * BIDEN" logo up top automatically floats to left side of the header and its width gets changed to 36px (thereby "hiding" the "OBAMA BIDEN" text).
How did the developers of this page achieve this effect? Is this javascript/jquery driven, or purely a CSS trick?
Ideas?
