Before I add the completed menu graphic to the bottom layer of the page, I make sure of two things:

1. That the width of the menu matches the most common screen resolution used on the Internet today, which according to many experts is 1024 x 768. The dimensions of the menu graphic I use are 1024px X 149px.

2. That the hexadecimal color of the defining tab and the page below it match. I do this to give a seamless appearance to the whole page, so that it looks like the single inside page of a file folder. For example, I set the body background color of this page to hexadecimal #F0F9FE to match the color of the defining introduction tab.

I enclose the 1024px X 149px menu graphic, which includes logo & tabs, within division tags with the following attributes: position: absolute; left:-25; top: 0; width: 1024; text-align: justify; z-index: 1; It is especially important to make sure the z-index is set at 1, which makes this very nearly the bottom layer. Dreamweaver automatically assigns the next higher z-index to each new layer that is created. For instance, among its other attributes, the introtab division tag, a new layer, will have a Z-index of 2.
