A terminal and a page generation method

The application relates to a terminal and a page generation method. The page generation method relates to the technical field of display devices. In the page generation method, when it is determined according to page information of a target page that a target content area in the target page contains a target function control, reference size information of a reference page is acquired; a reference direction of the target content area is selected from a width direction and a height direction according to a scrolling direction of the target content area; a scaling ratio of the target content area is determined according to actual pixel numbers of the target content area in the reference direction and reference pixel numbers of a reference content area in the reference direction in the reference size information; the reference size of the target function control in the reference content area in the reference size information is scaled according to the scaling ratio, so that the display size of the target function control in the target content area is obtained; and the target page is generated according to the page information and the display size of the target function control in the target content area, thereby improving the page display effect.
