信息技术 W3C 网络内容无障碍指南（WCAG）2.2

[中文适用范围]： Web内容无障碍指南(WCAG) 2.2 定义了如何使Web内容对残疾人更加无障碍。无障碍涉及各种残疾，包括视觉、听觉、身体、言语、认知、语言、学习和神经性残疾。虽然这些指南涵盖了广泛的问题，但它们无法解决所有类型、程度和组合残疾人群的需求。这些指南也使具有变化能力的老年人和其他用户的Web内容更加可用。 [外文原描述]： Web Content Accessibility Guidelines (WCAG) 2.2 defines how to make Web content more accessible to people with disabilities. Accessibility involves a wide range of disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities. Although these guidelines cover a wide range of issues, they are not able to address the needs of people with all types, degrees, and combinations of disability. These guidelines also make Web content more usable by older individuals with changing abilities due to aging and often improve usability for users in general. WCAG 2.2 success criteria are written as testable statements that are not technology-specific. Guidance about satisfying the success criteria in specific technologies, as well as general information about interpreting the success criteria, is provided in separate documents. The WCAG 2.2 standard, technical and educational material supporting implementation of WCAG 2.2, and translations of WCAG 2.2 are available from the Web Content Accessibility Guidelines (WCAG) Overview .
