The document outlines the key elements and principles of design, including line, shape, color, and texture as elements, and balance, emphasis, unity, and rhythm as principles of design. It provides descriptions of the principles of balance, emphasizing that it holds a design together, looks unified, and feels harmonious, whether through symmetrical or asymmetrical balance. Emphasis creates a focal point supported by accents to establish a visual hierarchy and path. Unity makes elements look like they belong together through common bonds, while rhythm creates a sense of movement through repeating or varying elements in a pattern.
