Grey lines down side in Alante Pro

I have been trying to remove the grey lines down the side of my pages as well as the one grey line under the title image. I have tried a variety of css lines in custom css with now luck. I am guessing I am missing something easy but wanted to see if anyone else has figured this out. I have a couple of other pages on a different site using a much simpler theme with no such lines so think it is a page or background object that I can’t seem to get rid of.
Any ideas or direction greatly appreciated.
