collapsed div with overflow hidden
===

I want to understand why the elements of my first div has not been shown on my page.

Take a look at the code: http://jsfiddle.net/ny48t/1/

The div MenuAreaLogada is collapsed. I learned the I should put overflow: hidden in div that has no content. I put it but it doesn't work.

I want to have my page divided in two divs: one at top and the other bellow the first.
