Web Content Accessibility Guidelines (WCAG) 2.1 aims at making web content more accessible and rafa.org.uk is 100% WCAG 2.1 compliant.
Being WCAG 2.1 compliant allows your website to reach a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photosensitivity and combinations of these, and is extremely important in making your web content more usable.
Colour schemes have also been set up to meet these requirements.
