The document discusses the principles of design including balance, rhythm, proportion, contrast, unity, and variety. It defines each principle and provides examples. Balance can be formal, with symmetrical halves, or informal with asymmetric but visually balanced elements. Rhythm guides the eye across the page through repeated elements. Proportion concerns the size relationship between elements based on their importance. Contrast creates interest through differences in elements. Unity deals with the harmonious relationship of all elements to effectively communicate the message. Variety adds interest but too much can be chaotic. Good planning and following guidelines for the audience ensures a quality design.
