Thanks so much for your answers.
I got the .single by trying to follow something in the tutorials. Stab in the dark, sorry about that.
I still have bubbles on the background of the wrapper. The page is white, but the bubbles are on the sides.
I want to remove the site wide background in the wrapper from one page only.
I should have been more clear in my question. I am a little rusty.
Thanks for being so willing to help.
