1. The Legal and Ethical Imperative of Web Accessibility
Web accessibility ensures that individuals using screen readers, keyboard-only navigation, or high-contrast display modes can interact with your website effortlessly. Meeting WCAG 2.1 AA standards is also required under the Americans with Disabilities Act (ADA) and European Accessibility Act (EAA).
2. Core Accessibility Standards for Forms
- Explicit Semantic Labels: Every input must be tied to a
<label for="...">element with matching IDs. - Full Keyboard Navigability: Users must be able to TAB through all fields, checkboxes, and buttons with visible focus rings.
- Color Contrast Compliance: Text and border contrast must satisfy minimum 4.5:1 ratios against background colors.
- Accessible Error Announcements: Use ARIA live regions so screen readers announce validation errors without visual cues.
