I was recently asked: " How can I hide the side nav bar on the main homepage layout ?? I want to be able to use the side NAV with in the team site etc etc, but I don't want it on the front page.. " There are a couple of ways to do this in SharePoint 2010 . If you are using a non-publishing site you can add a Content Editor Web Part to the page and add the following to the HTML Source. <Style> body #s4-leftpanel { display: none; } .s4-ca { margin-left: 0px; } </style> Basically the CSS above hides the left navigation Div, and then sets the content area to not have a left margin. Once you are done, simply modify the web part and hide it on the page. If you are using a publishing site for your homepage simply add the same styles specified above to a custom page layout. That way if you have a need for other pages that do not need the left side navigation you can re-use the page layout.
