To change the design of the navigation bar, you'll need to be able to use CSS. The navigation bar is a particularly tricky element to style well, and you'll need to be able to understand the page source (usually F12 in your browser).

You might want to consider contacting User:CzechOut, who is the admin at TARDIS Data Core responsible for most of their custom styling, and ask him to point you to that wiki's CSS. It may be a good starting point to work from.
