The Web Accessibility Initiative (WAI) is responsible for implementing the World Wide Web Consortium's (W3C) commitment to making the Web accessible to all people. The WAI is a recognized authority for the development of Web accessibility guidelines. Each checkpoint has a priority level assigned based on the checkpoint's impact on accessibility.
A Web content developer must satisfy this checkpoint. Otherwise, one or more groups will find it impossible to access information in the document. Satisfying this checkpoint is a basic requirement for some groups to be able to use Web documents.

Accessible Web design will provide equal access to the information and opportunities on the Internet. In addition to making information easier to access, benefits of accessible Web design include the following:
