title: Cannot make height 100% of div
body: <p>I have tried multiple things but for some reason no matter what I tray I cannot make my inner divs height 100% of the page, and it leaves me with half page looking divs through out my site. I think a part of the problem is because I have a fixed footer but I cant figure out or find a way around this, especially because I want the site to be responsive. Here is an example of the problem on my site that shows the problem. I believe I need the height of "container-fluid" div to be 100%. </p>
  
  <p>to clarify, I want the white part to be stretched till the bottom of the page.</p>
