Making the #Content section different depending on the page

I want the home page content section to be full width, but the content section of posts to keep the 50px padding that they have. Originally, my post pages looked bad because the text went right to the edge, so we added a 50px padding to left and right of the #content section, but now my full width banners on my home page are ruined. Can I somehow define different content section overrides to different pages?
