This page provides a list of high-quality and trusted web accessibility resources and tools, aimed at supporting accessible web design, development, and testing.
Here you can browse accessibility resources by category: standards & legislation, guidelines & checklists, code inspection & validation tools, screen reading & color contrast tools, pdf & word tools, courses, certifications, and advocates and companies.

Accessibility Resources: Wrap Up
There are a variety of web accessibility resources available online. Some of the top resources include the Web Accessibility Initiative (WAI) website, the W3C's Web Content Accessibility Guidelines (WCAG), and the US Department of Justice's ADA website.
These resources provide information on how to make websites accessible to people with disabilities. They also provide guidelines and standards that web developers can follow to ensure that their sites are accessible.
Having an accessible website is no longer an option; it is a must-have. Because it is important that the Internet is accessible to everyone in order to provide equal access and opportunity to people with disabilities.
And accessibility can no longer be an afterthought, or a nice-to-have, because…
The U.S. Supreme Court has cleared the way for people with disabilities to sue retailers if their websites are not accessible. This has far-reaching implications for all businesses because it puts them on notice that not only must their physical locations be ADA compliant, but their websites and mobile apps must be accessible as well.
