Why Accessibility Matters
Legal Requirement
Many countries now legally require websites to meet WCAG 2.1 AA standards (ADA in US, EAA in Europe). Failing to comply can lead to lawsuits.
User Experience
Better contrast isn't just for the visually impaired. It helps everyone read your content on sunny days or low-quality screens.
The Guidelines
- AA Standard for public websites.
- AAA High standard for specialized apps.
