Web Content Accessibility Guidelines or WCAG are developed by the Web Accessibility Initiative (WAI) which is a group under the World Wide Web Consortium (W3C).

W3C's website describes WCAG as "documents explain[ing] how to make web content more accessible to people with disabilities. Web “content” generally refers to the information in a web page or web application".

The technical documents for meeting WCAG 2.0 were published on 12/11/2008.

The technical documents for meeting WCAG 2.1 were published on 6/5/2018 and they included additional criteria for achieving accessibility.

W3C states this on their website regarding the version differences: "WCAG 2.0 and WCAG 2.1 are both existing standards. WCAG 2.1 does not deprecate or supersede WCAG 2.0. W3C encourages you to use the most recent version of WCAG when developing or updating content or accessibility policies."

If a website already meets WCAG 2.0, it does not need to be immediately updated to meet WCAG 2.1, however, it is highly encouraged.

If a website was not ADA Accessible prior to June 2018 it is recommended that it be updated to meet WCAG 2.1 as the second version includes the first version's standards while adding additional ones.

Inside Real Estate's 'Hero' and 'Material' templates both comply with WCAG 2.1 AA.
