Contact Form on Side Bar Issues

Hi I'm trying to to emulate the look of the contact page of pixelhappy dot co for my client on his new website. We are staging it here: http://4f3.b71.myftpupload.com/contact/ What would we have to do to decrease the gap between the sidebar and the main content so it's more presentable like at the pixelhappy website? I'm thinking some side margins are in order for this page specifically I'm just having trouble coding the CSS. I'm also looking for a way to omit the side bar from the home page. When I click on Catch Responsive - Layout Options - Full Width (at the bottom of the edit screen for the home page) it doesn't save my selection. It keeps going back to default (which is not full width) Thank you
