==Web Principles==
* [[General Principles]]
These are the principles that drive how the web functions at the hardware and software level. The closer our designs come to aligning with these principles, the more "native" to the web our designs will be, and the more effective they will be.
* [[Web Principles]]
 
* [[Human-Computer Interaction Principles]]
* [[Rough consensus and running code]] - If everyone agrees we need images, for example, and someone gets images up and running, whoever gets there first will probably be the one setting the direction for the structure.
* [[Universal Design Principles]]
* [[Postel's Law]]- "Be liberal in what you accept and conservative in what you send". In other words, assume that the people who are sending you things don't know the protocol, but stick to the protocol when you send out to someone else.
* [[Cognitive Design Principles]]
* [[Priority of Constituencies]] - "In case of conflict, consider users over authors over implementers over specifiers, over theoretical purity." According to ''[https://abookapart.com/products/html5-for-web-designers HTML for Web Designers (1st edition)]'' by Jeremy Keith, this is one of the design principles used by the WHATWG to decide what changes in the HTML specs.

Design principles codify the behavioral research and/or design research known about specific User Experience topics. 

The term can also be used to describe the driving behavior behind a design or a design group. In other words Fitt's Law is a design principle that explains the relationship between an object and its target. "Set users up for success" is a design principle that describes one of any good company's design goals.

It's worth noting that many of the design principles listed below are Heuristics- that is to say, they're practical methods to decision making sufficient for immediate goals, but not always appropriate for in-depth or complex decisions.

Richard Dalton put together a list of characteristics and principles of UX For Richard, Characteristics are a vector between two points, and a user may be closer to one side or another. For each of those items we've listed the characteristic, its explanation, and the range from one side to the other. Richard lists only three principles: Relevant, Comprehensible, and Aesthetic.
