The Web Content Accessibility Guidelines (WCAG) 2.1 Level AA is the internationally recognised standard for digital accessibility, developed by the World Wide Web Consortium (W3C). It defines success criteria across four principles — perceivable, operable, understandable, and robust (POUR) — that make web content and applications accessible to people with visual, auditory, motor, speech, and cognitive disabilities. Level AA compliance is the most commonly adopted target and is referenced by legal frameworks worldwide, including the Americans with Disabilities Act (ADA), Section 508, the European Accessibility Act, and the UK Equality Act 2010. For any organisation with a digital presence, WCAG compliance is not just an ethical imperative — it is increasingly a legal requirement.

All content must be presentable to users in ways they can perceive — including text alternatives for non-text content, captions for multimedia, and adaptable content that can be presented without losing meaning.
User interface components and navigation must be operable by everyone — full keyboard accessibility, sufficient time for interaction, no seizure-inducing content, and multiple navigation pathways.
Information and interface operation must be understandable — readable text, predictable behaviour across pages, and clear input assistance with descriptive error messages.
Content must be robust enough to be interpreted reliably by a wide variety of user agents, including assistive technologies like screen readers, with valid HTML and proper ARIA attributes.
Text must have a contrast ratio of at least 4.5:1 against its background, and colour must not be the sole means of conveying information, distinguishing elements, or indicating actions.
We treat accessibility as a design constraint — not a QA checklist. Our design system tokens include WCAG-compliant colour palettes, focus indicators, and typography scales from the first commit. We build with semantic HTML, ARIA landmarks, and keyboard-operable interactions as standard, not as a layer added after visual design is complete. Every component in our design systems is tested against WCAG 2.1 Level AA criteria before it reaches production, and we use automated axe-core scanning integrated into CI/CD to catch regressions before they ship.
