Accessible Web Content and Application Requirements

Web accessibility benefits everyone. This includes people using a slow internet connection or people with limited technological knowledge.

The Accessible Information and Communication Standard requires organizations to remove barriers for people with disabilities who use their websites and view their web content.

Website and web application requirements are based on four accessibility principles:

Perceivable (visible to senses)
Operable (interaction that a user can perform)
Understandable (informative and how to operate)
Robust (used widely as technology evolves)

Software applications that are run on web servers and accessed by users through web browsers (not including mobile apps). Web applications, also called web apps, are programs that allow users to perform actions online.
