WCAG – Definition

Web Content Accessibility Guidelines — the internationally recognized standard defining how to make web content accessible to people with disabilities.

WCAG 2.1 AA is the conformance level most commonly required by law, including under the European Accessibility Act. Meeting it requires structural support in the CMS — required alt-text fields, pre-checked contrast on modules — rather than per-page manual review alone. WCAG is organized around four principles — perceivable, operable, understandable, and robust — covering a much broader range than the commonly cited examples of alt text and contrast: keyboard navigability, sufficient time limits, and clear navigation structure all fall under the same standard. Testing requires both automated scanning and manual testing with actual assistive technology like screen readers, since automated tools alone miss issues related to logical reading order that only a human would notice.
