Greyed background in margins of pages

I see a grey gradient in the background of the left and right side margins of my pages. How do I remove these so that it is just white across the page? www.nettnutrition.com Thanks!

`body .contentcontainer{background:none}` Add to Custom Code > Custom CSS. Thanks, Bryan
