Frontend Accessibility Patterns Practical accessibility patterns for React and Next.js. Covers the issues most commonly flagged in code review: missing form labels, incorrect ARIA usage, non-semantic interactive elements, and broken keyboard navigation. When to Activate Building or reviewing form components ( , ,

) Creating interactive elements (modals, dropdowns, tooltips, tabs) Using <div> or <span> with onClick Adding aria-* attributes to any element Implementing keyboard navigation or focus management Receiving accessibility feedback from code review tools (CodeRabbit, ESLint a11y) Building components that must support screen readers Form Accessibility Missing htmlFor / id pairing and disconnected error messages are the most common issues flagged in code review.
