There are many ways to do it. You can create a theme
for your pages examine the css classes used for the navigation and make changes to them. I have attached 2 videos demonstrating how I make some changes to navigation css classes. You may need to use !important
at some declarations where there is overwriting of style rules. Use firebug to examine exactly which classes are applied to the navigation elements. The default styles can not be completely removed since the styles are added from the assemblies of the rad control creating the menu.
Other option if you don`t want to use a Theme is to use one of the built in skins
and enter its name in the Navigation widget backend -> expand Design Settings and enter the name in Css Wrapper Class (skin) textbox.
You can enter the name of a css document you want to apply to the menu in this box too.
Other option is to create a css document with styles for the navigation and use Css Widget on the page ( or template) to add this styles when the page is requested.
All the best,
