How to Show or Hide or Auto Hide "Navbar Blogger"?

Before erasing navbar blogger (Navigation Bar), it’s better if I inform that this method is one of the Blogger TOS violation. If you still want to erase it, you can use the script below:



Hide Navbar:

#navbar-iframe { display:none}

Show Navbar:

#navbar-iframe { display:block }

Auto Hide:

#navbar-iframe{opacity:0.0;filter:alpha(Opacity=0)}
#navbar-iframe:hover{opacity:1.0;filter:alpha(Opacity=100, FinishedOpacity=100)}

How to do:
In the Edit HTML page, put the code above under the code <b:skin><![CDATA[/* and then save template.
