Removing Sharepoint’s 2010 Left Nav Bar

Most of Sharepoint Page Templates and Masterpages include a left navigation bar. To remove it, we have two options:

1. Implement a custom master page, or simplier,
2. Create a (layout) page that removes the master’s nav bar by:
1. Declaring an empty Content Placeholder for PlaceHolderLeftNavBar

<asp:Content ContentPlaceHolderId="PlaceHolderLeftNavBar" runat="server"/>

2. Modifying the div’s styles

<style type="text/css">
    body #s4-leftpanel {display:none;}
    .s4-ca {margin-left:0px;}
</style>
