The content above is clipped in a 100px by 100px box, with scrolling available to view overflowing content.

Most desktop browsers will display both horizontal and vertical scrollbars, whether or not any content is clipped. This can avoid problems with scrollbars appearing and disappearing in a dynamic environment. Printers may print overflowing content.
