Making content background dark again

The reason for choosing a dark backgrounod was because video generally
looks better on a dark background. I had switch it to a white background
for search because of a design decision to make the genre's scroll on
the navigation bar lighter than the nav bar which looked weird when the page
had a dark background. However I have since made the decision to make the
scroll black and just differentiate it with borders. This allows me to
return the page background to a dark color as I had previously did.
Adding wrapper under content ui-view

There was an issue with the hidden scroll in the nav showing in the
content view. This was fixed by having a static, non changing div
underneath the changing div and than giving it a higher z-index
than that of the nav.
