Web sites with heavy content sometimes use anchor links to navigate down the page. The problem with this type of JavaScript navigation is that the user can become confused. The JavaScript navigation suddenly disappeared, and the user can be unsure if they were sent to a new page or if the page just scrolled down. This JavaScript addresses this problem by animating to the anchor link. Active and visited states are also used to let the user know what content has already been read.
