How does this website achiev开发者_开发技巧e the scrolldown and than loading of the content?

I think it's amazing that the site gives you a scrolling down/up effect and that you're able to use the scrollbar to scroll ONLY the div that is in view, and not the etire site.

The loading of content after the div dropping down looks easy. You just animate the div in question into the required location and then fire an Ajax callback to load the content. I don't understand your point about the scrolling.
