The document discusses four principles of design - balance, alignment, repetition, and contrast. It provides examples of how to apply each principle and the effects they can have on a design, such as creating order, emphasis, and visual interest. Symmetry, asymmetry, radial balance and uneven placement are discussed in the context of balance. Horizontal, vertical, edge and center alignment are covered. Consistency through repetition and contrast using size, value, color and type are also explained.
