What You'll Learn
This intermediate-level guide walks you through how to implement accessibility standards step by step. Estimated time: 12 min.
Step 1: Audit current accessibility
Run automated audits with axe-core or Lighthouse and conduct manual testing with screen readers and keyboard navigation.
Step 2: Fix semantic HTML
Use proper heading hierarchy, landmark regions, form labels, and semantic elements instead of generic divs and spans.
Step 3: Implement keyboard navigation
Ensure all interactive elements are keyboard accessible with visible focus indicators and logical tab order.
Step 4: Add ARIA attributes
Use ARIA labels, roles, and states for custom components that need additional context for assistive technologies.
Step 5: Test with real users
Conduct usability testing with users who have disabilities and incorporate their feedback into your design and development process.
Frequently Asked Questions
What accessibility standard should I target?▾
WCAG 2.1 Level AA is the industry standard and legal requirement in many jurisdictions. Level AAA is aspirational for most applications.
What are the most common accessibility issues?▾
Missing alt text, low color contrast, unlabeled form fields, missing keyboard navigation, and incorrect heading hierarchy are the most frequently found issues.
Do accessibility requirements slow down development?▾
Building accessible from the start adds 5-10% to development time. Retrofitting accessibility is 3-5x more expensive. Accessible design benefits all users, not just those with disabilities.
