Content Section

The purpose of this arrow demo is to indicate that there is further content down the page. While studies have generally shown that users do, in fact, scroll (thus killing the worries about page fold), it still has become somewhat fashionable to indicate scroll intent.

A subtle animation triggered after a period of time draws attention to the scroll indicator. Some jQuery hides the indicator after the user begins scrolling.
