This navigation bar uses the same HTML coding as the 1st Navigation Bar. A few changes in the CSS styles are what make it centered instead of flush left.
text-align:center; in the #nav is what centers the navigation.
In the decorative items - we set our styles to have a border on the left of our buttons, but we don't want the first item to have it on the left of it, so by telling the first-child to have none, it deletes that first border.
