Actually you can remove this Blogger Navbar by some coding. Here we discuss how to hide the Blogger Navbar...very easy, just follow this entire tutorial. Here, I give you two techniques...
Firstly you need login to your Blogger Dashboard. Then go to Template tab and choose Edit > HTML.

Technique One:

On that Edit Template box, you just need to paste this code just before ]]></b:skin>:

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

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

The above codes HIDE the Navbar completely.

Technique Two:

On that Edit Template box, you just need to paste this code just before ]]></b:skin>:

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

The above codes HIDE the Navbar and reappear on mouse over.
