A display system adapts a display page to a small display area using semantic information indicated by portions of the display page that are designated as cacheable. The display system adapts a display page by identifying leaf fragments, that is, fragments that contain no other fragments. The display system then determines whether each leaf fragment is a block that can be displayed as a unit in the display area or should be subdivided into blocks that each can be displayed as a unit in the display area. The display system then displays the display page on a block-by-block basis.
