Auto Hide Blogger Navbar

This is a quick and easy hack to allow the Blogger navbar at the top of the page to appear to have auto-hide.

Add the following .css to your stylesheet:

#navbar-iframe{opacity:0.0;filter:alpha(Opacity=0)}
#navbar-iframe:hover{opacity:.45;filter: alpha(opacity=45); -moz-opacity: 0.45;)}

Before checking, please check if it's against term and condition :)
Happy blogging :)
