Planning the flow of your Web site can allow you to envision what you need to create and plan a navigation scheme for the site. For example, you may want a navigation bar for the index.html page and top level pages that looks like this:
| Home | Work | Family | Hobbies |
On the next level pages, you may just want links back to their pointing pages or also point people back to the Home page. You've got lots of options and what you decide to do is up to you, however, it's a good idea to think about these issues BEFORE you start creating pages.
