The html and code tags are in the editor for a reason.
You don't have any of it in your navbar yet, cuz you haven't added it. You need to modify your code to be like how he did it. If I were you, I'd make a new style and play with the navbar in there. It's gonna take some effort on your part - you can't just add a couple of words and have it look like his. You will need to rewrite your whole navbar - and you'll have to think about what to do about those drop-down links.
