Keywords:
Americans with Disabilities Act (ADA), Digital accessibility, European Accessibility Act (EAA), Inclusive design, POUR principles, Single-Page Applications (SPAs), Universal design, WAI-ARIA, Web accessibility, WCAG 2.2Abstract
This paper examines the critical role of web accessibility in modern digital design, framed by the latest WCAG 2.2 standards. It posits that accessibility is a fundamental ethical and civil rights issue, extending beyond permanent disabilities to benefit all users through the “curb-cut effect.” The article deconstructs the WCAG 2.2 framework, detailing its four POUR principles (Perceivable, Operable, Understandable, Robust), hierarchical structure, and new success criteria targeting mobile, cognitive, and motor accessibility. A comprehensive business case is presented, highlighting the significant market opportunity, direct ROI, and SEO benefits of inclusive design. The legal landscape is analyzed, focusing on the Americans with Disabilities Act (ADA) and the European Accessibility Act (EAA) as key drivers of compliance. Finally, implementation strategies for complex technologies such as Single-Page Applications (SPAs) using WAI-ARIA are discussed, alongside a forward-looking perspective on integrating Universal Design principles to create a natively inclusive web.
