The web is accessible by default, and in this talk, I cover the four principles of accessibility. We’ll start with a little history lesson on how POUR began and then we will take a walk through the four principles of accessibility, or “POUR”. Perceivable, Operable, Understandable, and Robust.
These four principles in WCAG 2.1 will be covered and explained to users of all levels. All recommendations that are made for accessibility best practices are based on the four principles of accessibility.
We will also cover some common areas where failures of accessibility lie and how decisions affect accessibility with some real-world examples of how the four principles of accessibility weren’t achieved and examples of how they can be achieved.
