All designs have certain basic elements or building blocks chosen to convey the message — beyond the actual words or photos used. How we place those items on the page determines the structure of our designs and affects the overall readability and determines how well our design communicates the desired message. The principles of design govern that placement and structure.
Rules are not necessarily sacred, principles are. Franklin D. Roosevelt
Rules will have exceptions. Design patterns will fade away and new ones will emerge. Principles exist at a deeper level than rules and patterns - they are the underlying truths about interaction and human tendencies that should inform all interface design decisions.
These principles are the foundation of all the following design patterns and development guidance.
