Web accessibility refers to the design and development of web content that is accessible to all people, including those with physical, sensory, or cognitive disabilities. An accessible website allows people with disabilities to consume content, navigate, and interact with the site using techniques like alt text for images, keyboard navigation, screen reader support, and appropriate color contrasts. Accessibility is not only an ethical obligation but often legally mandated to ensure equal access to digital content for all. Web standards like the Web Content Accessibility Guidelines (WCAG) provide clear recommendations for improving the accessibility of websites.
