Make the banner the same for every desktop size

[MT27]

Hi, i need help in order to make the banner on the home page have the same margin-top in every desktop screen. More specifically I am trying to put my logo inside that circle that fits into the Parthenon.  But when I do it for the big screen it destroys the small screen, can you help me keep it the same for every screen size? thank you
