Adding this type of navigation to your site couldn’t be simpler: 1. Within the <head> tags, add the preceding code (from Listing 16-1) inside and including the <style> and </style> tags. 2. Add links inside individual <h4> tags. 3. Make sure that the entire menu is inside a <div> tag with an id attribute of navbar. If you add the CSS to your site via a link to a site-wide external style sheet (see Chapters 9 and 10 for more information on style sheets), you can add, change, or delete menu-bar links on your site at any time without having to touch a single line of CSS or JavaScript. You simply add or modify your <a href> tags. Slick, huh?
