I have been doing some more research on navigation bars and have some great examples of FIXED Navigation Menus. These either hover or are always present at the top, bottom or side or wait off screen. It is so cool! Zac Rutherford writes about this for speckyboy design magazine. See his article online – 30 Fantastic Examples of Fixed Navigation Menus in website design.
Also interesting is the website CSSDeck I love how they have a pop out window so you can see the code.
