Web accessibility is how easy it is for a person with disabilities to use a web page. An accessible web page is easy for people with disabilities to understand and navigate. There are several different disabilities that can interfere with a person's ability to use a web page. These include, but are not limited to visual and auditory impairments, mobility issues, cognitive issues and risk of seizures. Guidelines have been set in place to ensure that people with disabilities are able to use websites.
In the United States there are two primary sets of guidelines that govern accessibility in website design. These two sets of guidelines are WCAG and Section 508.
Section 508 Amendment to the Rehabilitation Act of 1973 was passed by congress in 1998, and updated in 2017, to ensure that people with disabilities are able to access websites. To find out more information about this law please read the Section 508 Guidelines
