Background image does not show if content area, only in header and footer area!

Hi there,

If you want the body background image to show in the content area as well, then your Content background color needs to have transparency instead of just white:

Let me know if this helps :)

That didn't help. I had to go to the settings for each page and go to the layout section and click on the "Contained" setting for every page. Isn't there a way to set this globally?

Not sure what you mean?

The container option has nothing to do with background color.

You can set the container option globally using the Layout Element:
