Accessibility (WCAG) Compliance Guidelines

Web accessibility ensures that websites are usable by everyone, including individuals with disabilities. WCAG (Web Content Accessibility Guidelines) 2.1 and 2.2 set international standards for accessibility. Compliance with these guidelines is crucial for legal adherence, inclusivity, and improved user experience.

Why WCAG Compliance Matters

• Legal Requirement: Compliance with ADA, Section 508, and EU accessibility laws.

• Improves User Experience: Accessible for visually impaired, motor-disabled, and cognitively challenged users.

• Boosts SEO: Accessible sites rank higher on Google.

• Expands Audience Reach: Ensures all users, including those with disabilities, can access your content.

• Prevents Legal Risks: Avoids lawsuits related to non-compliance.

Understanding WCAG Compliance Levels

1. Level A (Basic Accessibility) – Minimal compliance, addressing critical barriers.

2. Level AA (Standard Compliance) – Required by most legal frameworks (ADA, Section 508).

3. Level AAA (Advanced Compliance) – Highest accessibility standard for government/public sites.

Tip: Aim for WCAG 2.1 AA compliance to meet most legal requirements.
