Test-driven, Z-layered webpages

I implemented a hideable <div> using JavaScript from code samples from Pixel Development. I also separated the content from the style of the div using their suggestion.

I created my first JsUnit test of a function I wrote here. It tests the JavaScript functions that make a div appear, disappear and a function that returns its hidden status. I also have a graphical test. It is not necessary for JsUnit to work.
