Online Information System with Backward Continuous Scrolling

A web page may be rendered for display on a client device. The rendered web page may be based on a first document. It may be determined that a first scroll position of the rendered web page is above a first threshold scroll position. Possibly responsive to determining that the first scroll position of the rendered web page is above the first threshold scroll position, a second document may be requested and received from a server device. The web page may be re-rendered for display on the client device. The re-rendered web page may include content from the second document followed by content from the first document.
