100% DIV height for doc not viewpoint - html

Question

I'm trying to make a div fill the entire doc height, not just the viewpoint height. When 100% height is set on body, html and the div, the div will fill 100% of the viewpoint. However, when another div make the doc height go beyond the viewpoint, and the page is scrolled, the 100% height stayed at the original viewpoint height.
I've make the follow jsfiddle to demonstrate the problem:

Sorry if this is a repeat question, I have looked through many others questions and can't find an answer which works for my problem. I'm new to developing responsive sites, and I'd really appreciate some help.
