Removing the Blogger Navbar

It is an oldie, but worth mentioning.
You can remove the blue Blogger navigation bar that is at the top of each page by adding a single line of CSS to the skin of your blog.
From your dashboard go to the Layout | Edit HTML screen and scroll down to the skin part of the blog.
Feel free to save your current template first by downloading it, but it is not really necessary as this is not a very risky modification.

<b:skin><![CDATA[/*
 ...
 ...
#navbar {display:none;}
 ...
 ...
]]></b:skin>

Save and display, and finally you will be rid of the navigation bar.
