Building Accessible Web Applications: A Practical Guide

Web accessibility isn't just a legal requirement—it's a fundamental aspect of good design. When we build accessible applications, we create better experiences for all users, not just those with disabilities.

Understanding WCAG 2.2

The Web Content Accessibility Guidelines provide a framework for making web content accessible. WCAG 2.2 introduces new success criteria focused on mobile accessibility, cognitive disabilities, and users with low vision.

Semantic HTML is Your Foundation

Before reaching for ARIA attributes, ensure your HTML is semantic. Use headings in order, choose the right elements for the job, and let the browser do the heavy lifting.

Keyboard Navigation

Every interactive element must be reachable and operable via keyboard. Test your applications without a mouse to ensure all users can navigate your content effectively.

Color and Contrast

Maintain a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Don't rely on color alone to convey information—always provide secondary indicators.
