How is asymmetry characterized in layout design?

Asymmetry in layout design is characterized by differing proportions of text and graphics, which creates a dynamic and visually interesting presentation. This approach contrasts with symmetrical layout, where elements are arranged in a balanced manner on either side of a central axis. By utilizing asymmetry, designers can draw attention to specific parts of the composition, guide the viewer's eye, and enhance the overall visual hierarchy. This method allows for flexibility in design and can evoke specific emotions or reactions from the audience. The other options refer to characteristics or practices in design that do not specifically define asymmetry; for instance, balanced presentations and style guides pertain more to structured or uniform approaches rather than the varied and dynamic nature that asymmetry embodies. Additionally, the use of website-safe fonts relates to typography choices rather than the inherent layout structure itself.
