randommaker.... hahaha... I'm so unsure of what you're asking.
The navbar is just HTML/possibly server-side scripted. And the site is nothing special. It's on each of the pages.
I'm responding to this post because I think what you're really asking about is the navbar image (button highlight) for what page is being viewed. For instance, on the home page the "Home" has the white background image, and if you click on the "Freebies" or "Forums" link, when you go to their page, they will have the white background in the navbar.
Is that what you're asking?
If so, you can do this with parameter control, if your navbar is scripted, or you can do this with regular Javascript, if you just parse the URL. For instance, you can use Javascript to get the address bar's URL, parse it for the word "forum" if it exists, change that button's css class to "on"
