Continuity . Hierarchical design pages are a way to convey visual information. For the perception of information in a certain frame, people usually observe points, lines, and faces. During the browsing process, the outlines, dividing lines, and points in the page have certain visual stimuli for the viewer, so it is important to determine the order of controlling visual information in the page design based on the way people observe. Consecutive appearance will deepen the user's visual familiarity, which is the most basic way for the visual process. The clearly ordered and very smooth and continuous interface is more readable, and users can understand the content of the interface by quick browsing, making the browsing process more pleasant.
