Why Web Accessibility is Important

Web accessibility refers to designing and developing websites so that all people, including individuals with disabilities, can perceive, understand, navigate, and interact with online content. The World Wide Web Consortium (W3C) created the Web Content Accessibility Guidelines (WCAG) to provide internationally recognized standards for making web content accessible. (Web Content Accessibility Guidelines (WCAG) 2.2, 2023) WCAG is built around four foundational principles: Perceivable, Operable, Understandable, and Robust (POUR). (Initiative, 2008) These principles guide developers and designers in creating inclusive digital experiences.
