What is a W3C Accessibility Guidelines (WCAG)?
Understanding W3C Accessibility Guidelines (WCAG) in E-commerce
Quick Definition
W3C Web Content Accessibility Guidelines (WCAG) are internationally recognized standards defining how digital content should be designed to ensure equal access for people with disabilities. These guidelines provide a comprehensive framework for creating web experiences that are perceivable, operable, understandable, and robust for users with diverse abilities and assistive technologies.
Understanding WCAG Accessibility Standards
Core WCAG Principles
- •Perceivable: Information must be presentable to users in ways they can perceive, regardless of sensory capabilities
- •Operable: User interface and navigation must be functional for everyone, including keyboard-only users
- •Understandable: Content and operation must be clear and predictable for all users
- •Robust: Content must be compatible with current and future assistive technologies
Compliance Levels
| Level | Requirements | Implementation Complexity |
|---|---|---|
| A (Minimum) | Basic accessibility features | Low |
| AA (Recommended) | Moderate accessibility improvements | Medium |
| AAA (Maximum) | Comprehensive accessibility features | High |
