So me and my daughter have been working on this website and have gotten it to be centered with different browser windows and resolutions. Web designing is very new to me so I don't understand a lot of it. Anyway, I am trying to get the nav bar to move in bigger monitor sizes. In my daughter's monitor(smaller), the navbar shifts to the right a bit. And in my computer(larger) the nav bar shift a lot to the right. How do I get the nav bar to be in the position I placed it in dreamweaver??

The site we are working on:
