Digital accessibility refers to designing and developing digital products, such as websites, mobile apps, and electronic documents, so all users can easily use and interact with them — including users with disabilities. For example, developers provide alternative text for images for visually impaired users, place captions on videos for hearing-impaired users, and ensure those with motor disabilities can navigate websites using only a keyboard.
The Web Content Accessibility Guidelines (WCAG) are a comprehensive set of digital accessibility standards published by the Web Accessibility Initiative and the World Wide Web Consortium. These guidelines are the foundational benchmark against which digital accessibility is measured. WCAG consists of thirteen guidelines organized around the four principles that web content must be Perceivable, Operable, Understandable and Robust for users with disabilities.
