Hide Current Navigation Panel in SharePoint 2013

Create your own css file and add to the site collection’s Style Library.

The css should contain:

<style>

.ms-core-navigation { DISPLAY: none }

#contentBox { margin-left: 0px }

</style>

Now goto the site collection’s Site Settings page. Click on the ‘Master page’ link under ‘Look and Feel’, expand the Alternate CSS URL section and select the css file.

The Focus on Content button (top right) also exhibits similar behaviour – see http://www.learningsharepoint.com/2012/12/03/hide-quick-launchleft-nav-using-focus-on-content-in-sharepoint-2013/
