CSS: Sidebar 100% height no scrolling

Question

I want a sidebar which takes the full height of the screen and doesn't change when scrolling down.

So when I scroll only the contents changes but the navbar stays always the same.

I made a first example: http://jsfiddle.net/CwSD6/

But the none-scroll functionality is missing...

Regards

EDIT: You need to use position: fixed, and top, bottom, left with value 0. http://jsfiddle.net/CwSD6/1/

Answer 1

it can be done by doing position: fixed; in <aside>
