Building Accessible Web Apps in 2025: Beyond WCAG Compliance
Web accessibility isn't just a legal requirement — it's good engineering. Teams that invest in accessibility ship fewer bugs, reach larger audiences, and build more maintainable code.
Why Accessibility Improves Everyone's Experience
Accessibility features like keyboard navigation, sufficient color contrast, and clear focus indicators don't just help users with disabilities — they improve the experience for everyone using a keyboard, a slow connection, or a bright outdoor environment.
The New WCAG 2.2 Requirements That Actually Matter
WCAG 2.2 introduced Focus Not Obscured, Dragging Alternatives, and minimum Target Size requirements. These improvements are straightforward to implement when building on a solid foundation — which is why we always start accessibility work alongside performance, as described in our React Server Components guide.
Automated Testing Catches Only 30% of Issues
Tools like Lighthouse and axe-core are valuable but limited. They cannot detect: insufficient focus visibility in dark mode, confusing reading order, or poorly labeled form relationships. Manual testing with a screen reader (NVDA on Windows, VoiceOver on Mac) is essential.
Building an Accessible Component Library
The highest ROI approach is investing in an accessible base component library. Every button, form field, modal, and dropdown built once with proper ARIA roles saves engineering time on every future feature. This pairs directly with TypeScript's strict mode to eliminate entire categories of interface bugs at compile time.
Legal Risk Is Increasing
ADA Title III lawsuits targeting websites have increased 300% since 2018. If you'd like a compliance audit of your web application, contact our team — we offer accessibility reviews as part of our software development services.
