navigation bars and css

On the advice of listmembers, I am redesigning our website using CSS for
layout instead of tables.  I'm a little enamored with the navigation bar I
created in Dreamweaver.  Is it acceptable when doing layout with CSS to
use this type of navigation bar, or should I use an alternate method to
create the same or similar effect?  

Thanks in advance for your advice!
