Hide the nav-bar in your blogger blog

If you want to hide the nav-bar in your blogger blog, here's what you should do (these instructions refer to the "new" Blogger layouts templates):

1. Go to Template>Edit HTML in your Blogger dashboard and first back-up your template to ensure you can restore it if you make unwanted mistakes!
2. Next, find this line in the template: </b:skin>
3. Just before this line, insert the following lines of code: 

#navbar-iframe {
height:0px;
visibility:hidden;
display:none
}

You can preview your template to see the effect in action, and then save your template to save the changes for good.
