POUR
Abbreviation for Perceivable, Operable, Understandable, Robust
In short and in plain language
POUR sums up the main ideas of the rules for barrier-free web content.
Content should be possible to perceive and to use. It should also be easy to understand and robust.
Each test point in the rules belongs to one of these ideas.
So reports on checks often sort their results this way.
Definition
POUR sums up the core principles of WCAG: perceivable, operable, understandable and robust. Each success criterion in the guidelines is assigned to one of these principles. Accessibility audit reports therefore often group their results accordingly.
