Hide Left Navigation in SharePoint 2010

Here's a quick reusable way to hide the left navigation.  Create a text file called "HideLeftNav.txt" in a document library.  Add the following css code: <style type="text/css"> /*--Hide Quick Launch --*/ #s4-leftpanel{ display:none } .s4-ca{ margin-left:0px } </style>    Edit the page you want to hide the nav on, add a content editor webpart. Then, simply reference the url to the HideLeftNav.txt file and you are done.
