You determine the names of the pages and their order within the navigation menu, and whether they are part of your main navigation or perhaps a secondary navigation, and the builder will take care of all of the linking details.
Site by Nite has taken one of the most complex, time consuming tasks of custom web design, and automated everything for you. And the menus can include image style buttons with actual web text for the wording so you can change them on the fly at will. The images will expand or contract as needed, and you still get real text which helps search engines index your site and makes the navigation more accessible to any users with disabilities.
Talk to any professional web designer and they'll tell you that they often spend as much time just developing the navigation menu of a site as creating the rest of the page. Instead of hours, you'll do it in minutes! And that's time well spent.
