A secondary navigation intended for users who want a quick overview of the page content, and be able to easily move from one section of the page to the other.A fixed navigation with smooth, jQuery powered scroll. Nothing fancy here, yet a handy snippet for creating a secondary menu to quickly surf through the page content. We see this effect a lot these days, a good example I can think of is Disqus For Websites. A nice touch is to animate the logo and the main call-to-action button to slide in once the navigation becomes fixed.
