To provide a layout system that prevents a layout intended by a designer from being destroyed, a content delivery terminal segments a selected information container frame into information container frames that do not overlap with another information container frame, registers the segmented information container frames into a modification candidate list, selects one of the segmented information container frames from the modification candidate list, and modifies the selected information container frame to the selected modification candidate container frame. Regardless of the content of an article, the amount of information of the article, and the logical structure of the article, the information container frame is modified in size with the rectangular shape thereof maintained.
