How to Hide navbar for New Blogger

Blogger has started advertisement above the navbar (the usually blue navigation bar at the very top of a blog) on a random basis (now you see it, now you don't) and this has taken valuable space. See screen shot below:



Since that is taking valuable real estate plus the fact the theBlogger TOS (Terms of Service) did not specify that one must have it for the blog, I have decided to hide the navbar. 

There are various ways to do that, not all of them effective. I have found that the hack by Aditya to be effective.

Aditya's hack is simple. Here is my interpretation of his hack: Go to LAYOUT > EDIT HTML to open the template editor.Look for  and paste the following after that:

div.navbar {
opacity:0.0;
display:none;
}
