People should not need a high level of technical literacy to use the web. Web platform technologies should behave consistently and intuitively. We will build internationalization and localization capabilities into our specifications and websites, including support for different languages. Our specifications and websites are well internationalized, provide support for language and cultural adaptation, and support localization, so that our work is accessible to all users, regardless of language, writing system, or culture. We will accommodate people on low bandwidth networks and with low specification equipment. The web platform and the tools we use to create it must be accessible to people with disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities. Anyone should be able to meaningfully participate in the creation of specifications, user agents, and content, and the platform should enable a fully accessible end-user experience.
