The Web Accessibility Checker is a free validator available from the Adaptive Technology Resource Center in Ontario, Canada. The Web Accessibility Checker can check your website for compliance with both Section 508 and the Web Content Accessibility Guidelines.
This tutorial will cover the implications of color blindness for web accessibility. Color contrast guidelines for making content more perceivable will also be addressed.
The first principle of the Web Content Accessibility Guidelines (WCAG) requires us to create content that is perceivable to people who have sensory disabilities. This includes people who are blind or visually impaired. One way to accommodate people with visual disabilities is to provide alternative text for the images used on your website.
The Web Content Accessibility Guidelines (WCAG) are the international standards for website accessibility. The World Wide Web Consortium (W3C), the standards organization for the Web, maintains the WCAG. The latest version of the WCAG is version 2.
