Using full screen mode in FF or Chrome moves the logo too high

I have a Wordpress site at http://e3bldg.michianait.net. I have used CSS to position the logo. It looks fine in "unzoomed" mode, but when I select Window > Zoom (in FF on a Mac) the logo moves up and is partially hidden from view and the scroll bar won't bring it down.

Am I using the incorrect CSS to position the logo and then "zooming" alters the position?

Thanks
Mark

Could you clean it up first or check whether the error need to be solved or NOT ?
