The WCAG are international guidelines for creating accessible digital content. They were developed by the World Wide Web Consortium (W3C) and form the basis for many legal regulations, including the European Accessibility Act (EAA).

Purpose and application
The goal is to design websites, apps and documents in a way that makes them usable for everyone — including people with disabilities. The guidelines are built on four principles: perceivable, operable, understandable and robust.
WCAG defines three levels of accessibility: A, AA, and AAA. Level AA is the standard required by most regulations.
Examples of requirements
✔ ALT texts for images
✔ Sufficient color contrast
✔ Full keyboard accessibility
✔ Clear and understandable content and structure
Importance for businesses
WCAG compliance improves usability, ensures legal security and increases reach — both for people and search engines.
