specify css element in footer

trying to adjust the background-color of the footer area. I have tried dozens of combinations of css to try and select this specific area, but none work.
Please educate me on how to specify the (now white) footer area so I can make it black.

obviously .container_24 .grid_24 (or 12) is not the answer since that changes the entire page. I just want to change the tiny footer section at the very bottom of the page (again.. that is now white).

 

Hello,


Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.footer_wrapper{
background:black;
}
.footer_bottom{
background:black;
}
