There are 4 principles of WCAG 2.0, and to remember them quickly, you can think of this acronym, POUR.
This web principle is about processing web content by seeing, heating, or touching it. If there is one sense missing, the information should be perceivable through another sense.
In general, web content must have the ability to operate with both a keyboard and a mouse. However, it also means the ability to operate and correct mistakes through voice or other alternative input devices like switches or a head-controlled mouse.
The principle understandable is where web content is presented in a consistent, predictable, readable form that reduces the chances of making errors and can be understood by different users.
Robust is a web accessibility principle that adopts standards to function or be understood across a wide range of technologies. It should also allow to continue to function in the future as technologies change and evolve.
