Here's a review of what class and id mean, in terms of CSS. http://www.w3schools.com/css/css_selectors.asp They're "selectors". They allow you to name what it is you specifically want to style.

Open up your navbox code in source mode and search for "class" and "id". You'll get immediate "hits" when you do. So when you see, for example,  that means that in your CSS there must be: .hello { some sort of styling here }

When you see, in your CSS there must be:
 * 1) goodbye { some sort of styling here }

Because you'll want people to see these navboxes regardless of whether they're using the Monobook or Wikia skins, you'll want to make sure that the navbox code is either literally a part of your MediaWiki:Common.css, or at least imported directly into it. (You can see tardis:MediaWiki:Common.css, right at the very top, to understand how NavboxWP.css is @imported to Common.css.)
