What is web accessibility 2.1 (WCAG 2.1)

Web accessibility refers to the practice of making websites and web applications accessible to people with disabilities. This includes people with visual, auditory, physical, cognitive, and neurological disabilities.

Web Content Accessibility Guidelines (WCAG) 2.1 is a set of technical guidelines developed by the World Wide Web Consortium (W3C) to help make web content more accessible to people with disabilities. These guidelines provide a set of standards for web developers to follow when creating websites and web applications to ensure that they can be used by as many people as possible, regardless of their abilities or disabilities.

WCAG 2.1 includes a set of success criteria that outline specific requirements for web accessibility. These success criteria are organized into four principles: perceivable, operable, understandable, and robust.

Perceivable: Web content and user interfaces must be presented in a way that is perceivable to users, regardless of their sensory abilities. This includes providing text alternatives for non-text content, such as images and videos, and using color and contrast effectively to ensure that content is legible.

Operable: Web content and user interfaces must be operable by users, regardless of their physical abilities. This includes making sure that all functionality is available through keyboard controls and providing enough time for users to complete tasks.

Understandable: Web content and user interfaces must be understandable by users, regardless of their cognitive abilities. This includes using clear and simple language, providing clear instructions and feedback, and organizing content in a logical and intuitive way.

Robust: Web content and user interfaces must be robust enough to work with a variety of technologies and assistive technologies, including screen readers and other tools used by people with disabilities. This includes using semantic HTML markup and ensuring that content is compatible with different web browsers and devices.

By following the guidelines outlined in WCAG 2.1, web developers can create websites and web applications that are more accessible to people with disabilities and provide a better user experience for all users.
