What Is Web Accessibility?
Web accessibility means designing and developing websites so that people of all abilities and disabilities can use them effectively. An accessible website ensures that users with visual, auditory, motor, or cognitive impairments can perceive, understand, navigate, and interact with its content.
Why Accessibility Matters
-
Inclusive Experience: The web should be usable by everyone, regardless of physical or cognitive abilities.
-
Legal Compliance: Many countries enforce accessibility laws (such as the ADA in the U.S. or the RPwD Act in India). Non-compliance can lead to legal action.
-
Better User Experience: Accessible design benefits all users, including those on mobile devices, in noisy environments, or with slow internet connections.
-
SEO Benefits: Search engines favor well-structured, semantic content, which overlaps with accessibility best practices.
Core Principles of Web Accessibility (POUR)
The Web Content Accessibility Guidelines (WCAG) are built on four principles—POUR:
-
Perceivable: Content must be presented in ways users can perceive (e.g., text alternatives for images, captions for videos).
-
Operable: Interface components must be usable with a keyboard and provide enough time for interaction.
-
Understandable: Content and navigation should be clear and predictable.
-
Robust: Content should work reliably with assistive technologies like screen readers.
