WCAG 2.2 extends Web Content Accessibility Guidelines 2.1 [ WCAG21 ], which was published as a W3C Recommendation June 2018. Content that conforms
            to WCAG 2.2 also conforms to WCAG 2.0 and WCAG 2.1. The WG intends that for policies
            requiring conformance to WCAG 2.0 or WCAG 2.1, WCAG 2.2 can provide an alternate means
            of conformance. The publication of WCAG 2.2 does not deprecate or supersede WCAG 2.0
            or WCAG 2.1. While WCAG 2.0 and WCAG 2.1 remain W3C Recommendations, the W3C advises
            the use of WCAG 2.2 to maximize future applicability of accessibility efforts.
