How to get rid of the Blogger Navbar at the top ?

Hi, you know the thing that's on top of the blogger blog which allows you to flag/report blogger blog. I see some blogs don't have them.. I didn't found any option in the blogger settings to remove it.. How to get rid of them..?

Go to Layout > Edit html
and add this code on top of CSS code..

  Code:

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

Or you could use this bit of code, in the same spot of the template (same as last post suggested), between the "Title" & "CSS", at the top of the template.

  Code:

#navbar-iframe {
   display: none !important;
}

i generally use following simple code..

#navbar {display:none};
