• Contrast
  • Size, color, weight, opacity, etc
  • Creates a hierarchy of importance
• Repetition
  • Repeat similar elements (colors, shapes, sizes, etc) to make the design cohesive and balanced
• Alignment
  • All elements should have a locational relationship to each other (lined-up)
  • Directs the flow and direction of the user's focus
• Proximity
  • Groups similar components for clearer definitions
  • "Blocks" of ideas make a more interesting layout and will more likely hold the users attention
