using integrity, got 100% width of website. set the background to white, but still have the “edges” showing up like a piece of paper sitting on something. ??
I would like to put an image/ad right below the menu/header and above the content on the actual page.

I would like to put the above mentioned image(s) in the red block space.
the blue space shows the “paper edges” in question. How do I remove these so it just looks like one flush white background?
