2. Introduction to WCAG 2.0

Introduction to WCAG 2.0

Now that Lulu has a better understanding of what a web accessibility audit entails and has decided with certainty to move forward with one, she is seeking a recommended resource that might allow her webmaster to familiarize herself more thoroughly with the features of accessible web content. Without a doubt, WCAG 2.0 is the resource that she is looking for. Review the content below to understand the significance and purpose of this critical element of Lulu’s, and your, toolkit.

Though it is possible to conduct informal accessibility reviews with basic understanding of the types of barriers faced by people with disabilities, and knowledge of the common elements in web content that often produce barriers, a thorough, professional review requires a solid understanding of the W3C Web Content Accessibility Guidelines (WCAG 2.0, aka ISO/IEC 40500:2012).

This chapter will introduce you to WCAG (pronounced “wuh-kag”), which provides the basis for most international accessibility rules and legislation, along with its supporting documents. WCAG 2.0 should be a key element of your Web Accessibility Auditing Toolkit. You should develop a basic understanding of WCAG 2.0 to start, then use it and its supporting documents as references while conducting your audits and build upon the basics as you go about auditing web content.

Toolkit: Add the W3C Web Content Accessibility Guidelines (WCAG 2.0) to your Web Accessibility Auditing Toolkit. REQUIRED READING.
Key Point: As of June 5, 2018, WCAG 2.1 was released with 17 new checkpoints, extending WCAG 2.0 with additional guidelines that address accessibility across devices and for people with cognitive disabilities. Readers should refer to the newer version of the WCAG guidelines moving forward.
