Accessibility terms
Great software works for everyone, not just the majority
Accessibility is not a feature to add at the end — it is a quality dimension that affects every design and implementation decision. This category covers WCAG guidelines, ARIA attributes, keyboard navigation, screen reader compatibility, colour contrast, and the testing approaches that ensure your software genuinely works for users with disabilities. Accessible code is almost always better code.
