How do you change the page background

I cant find anywhere in the epsilon editor to change the background color or add an image.

Good morning

thank you for question
“change the background color or add an image.” - Where? which element or section? if you cant see options to change these properties then there is no option to change them, please give me little bit more information

The background on the pages themselves. Gotta be a way or this template has only white pages.
