===Web Content Accessibility Guidelines (WCAG)===
{{further|Web Content Accessibility Guidelines}}
The Web Content Accessibility Guidelines 1.0 (known as WCAG) were published as a W3C Recommendation on 5 May 1999. A supporting document, Techniques for Web Content Accessibility Guidelines 1.0<ref>{{cite web|url=http://www.w3.org/TR/WAI-WEBCONTENT-TECHS/ |title=Techniques for Web Content Accessibility Guidelines 1.0 – W3C Note 6 November 2000 |publisher=W3.org |access-date=28 July 2013}}</ref> was published as a W3C Note on 6 November 2000. WCAG 1.0 is a set of guidelines for making web content more accessible to persons with disabilities. They also help make web content more usable for other devices, including mobile devices (PDAs and cell phones).
The Web Content Accessibility Guidelines 1.0 are recognized as a de facto standard and have served as a basis for legislation and evaluation methodologies in many countries.

The WCAG working group published WCAG 2.0 as a Recommendation on 11 December 2008. WCAG 2.0 is based on very different requirements from WCAG 1.0:
* the guidelines needed to be technology-neutral, whereas WCAG 1.0 was strongly based on HTML and CSS;
* the guidelines needed to be worded as testable statements instead of instructions to authors.
The combination of more general applicability and higher precision proved very challenging.

In 2018, the WCAG working group published WCAG 2.1. This remains fundamentally similar to the guidance in WCAG 2.0, with some additional recommendations made in particular areas:<ref name="torontouniversity">{{cite web|url=https://pressbooks.library.torontomu.ca/pwaa/chapter/the-evolution-of-web-accessibility/|title=The Evolution of Web Accessibility|publisher=[[Toronto Metropolitan University]]|access-date=8 June 2023}}</ref>
