The best thing you'd best go with is to make your index page into frames

Frames allows you to convert more than 1 page into many pages. This saves alot of time if you'd need to add a new page to your navigation bar

I have a script set in frames (And in HTML) and it shows 3 pages: The header (For your banners), Navigation (For linking to all your pages) and main (which is what all the pages will show up on when you click a link in your navi)
