Problem Overview

Inaccessible pages exclude users and create legal and brand risk. Common gaps: missing alt text, unlabeled inputs, skipped heading levels, and no landmarks.

Why It Matters

Accessibility expands audience reach and often improves SEO and AI extractability through clearer structure.

Framework-Specific Explanation

Next.js components should preserve semantics — prefer native elements over div soups, and ensure routing libraries expose real links.

Step-by-Step Solution

  1. Audit key templates for landmarks (main, nav).
  2. Fix images and inputs missing alt/labels.
  3. Normalize heading hierarchy.
  4. Keyboard-test primary CTAs and dialogs.

Code Examples

<label for="email">Work email</label>
<input id="email" name="email" type="email" autocomplete="email" />
<img src="/chart.png" width="800" height="450" alt="Revenue trend over 12 months" />

Common Mistakes

  • Icon-only buttons without accessible names
  • Decorative images marked as content (or vice versa)
  • Skipping heading levels for visual style
  • Custom widgets without keyboard support

Validation Checklist

  • [ ] Images have meaningful alt (or empty alt if decorative)
  • [ ] Form controls associated with labels
  • [ ] One logical H1; no skipped levels
  • [ ] Main and nav landmarks present
  • [ ] Keyboard operable primary flows

AI Readiness Notes

Semantic structure helps assistants segment roles of page regions. Treat a11y as part of machine readability, not only compliance.

Deployment Checklist

  • [ ] Automated a11y checks in CI when available
  • [ ] Manual keyboard pass on signup and pricing
  • [ ] moneygap scan a11y findings reviewed
