This short article will set out the basic ideas underlying the World Wide Web Consortium’s Web Content Accessibility Guidelines 2 (WCAG 2).
Here is the shortest possible summary of the guidelines:
The WCAG 2 guidelines are based on four principles: all content must be Perceivable, Operable, Understandable and Robust.
- For each principle there are guidelines.
- For each guideline there are testable ‘success criteria’.
- For each guideline and success criteria there are related techniques.
Ok, if you are anything like me, that’s about as clear as mud. So to understand it, let’s start by defining what some of these words/principles mean; which we can do by translating them from WCAG speak to the much simpler, Jim speak.
