The purpose of accessibility standards in web development is to ensure that digital content is usable by people with disabilities. These standards, such as the Web Content Accessibility Guidelines (WCAG), provide a framework for creating websites that accommodate users with visual, auditory, physical, or cognitive impairments. By adhering to accessibility standards, developers can enhance user experience and ensure compliance with legal requirements. This promotes inclusivity, allowing all individuals equal access to information and services online. Ultimately, accessibility standards foster a more equitable digital landscape for users of diverse abilities.
