Where can I change the background color of the BODY

Where can I change the background color of the BODY, not the Background of the website, but the body where the slider and feature images are residing?

 

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

Code:

.main-content {
background-color: red;
}

Inplace of "red" put your color code.

 

You guys are awesome! Fast Response! THANK YOU!

 

One more... how can I make it a background picture, and where is the code for the background of the SLIDER. It doesn't change that.
