Web Content Accessibility Guidelines (WCAG) 2.1 lie the foundation to evaluate the accessibility of web content in a “technology-agnostic” way: this means that they are abstract enough so as to be applied no matter what technologies and tools are used to produce web content, yet be “practically enough” to be tested to check for content conformance.

In fact, WCAG 2.1 is organized as:

  • 4 main principles, that inspire all guidelines;
  • guidelines, rules that web content should conform to in order to satisfy the four principles;
  • success criteria, “practically testable” statements to check wether content respects a certain guideline or not.

Based on which guidelines are satisfied, content conformance to Web Content Accessibility Guidelines can be assessed on 3 different levels: A, AA, and AAA.
