How to remove the blogger bar

I found this piece of code to remove the blogger bar from the top of this page:

<style> #navbar-iframe { height:0px; visibility:hidden; display:none; } </style>

How to use it:

1. Go to the "Layout" tab
2. Go to "Edit HTML". Don't worry if you don't know what your looking at it isn't that complicated
3. Look for the symbol ""
4. Copy the code above and paste it right below the ""
5. Preview your changes to make sure you got it right
6. Save your changes.

I have seen rumors that you may so may get banned for using this hack so I disabled this hack on my blog for now while I confirm.
