Thanks for the assistance I received to separate the featured image from the body container below, so that my background image is now visible between them. I just discovered, however, that the right sidebar has separate boxes (is container that correct word here?) for each of the widgets, so the site’s background is now visible between them.
Is there a way I can bring this back to being one continuous box/container while still keeping space/background visible between my featured image/logo and the content box/container on all my pages?
Uh oh! In trying to see if I could figure out how to eliminate the space between the content area and right sidebar, I switched the setting in layout from separate containers to one container, which eliminated other customizations you’d helped me with, so I switched it back to separate containers. This seems to have overidden the code you gave me above.
