WCAG is a set of guidelines for making web content more accessible to people with disabilities. In other words, it’s not a law, but it does give you some specific criteria which will be helpful for accommodating users across a wide range of disabilities. WCAG is developed through the W3C process, with the goal of providing an international shared standard of meeting these needs. 

The four principles of WCAG compliance are that your web content is perceivableusers must be able to perceive the information being presented whether through sight, hearing, or touch; operational – do all of the navigable components of your website work? Are there any elements which require interaction that all users cannot perform?; understandable – the information presented and the method of operating your website must be easily understood; and robust – the content must be able to be reliably interpreted and used by most common assistive technologies.
