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.
