2. Introduction to WCAG 2.0

Activity: WCAG Scavenger Hunt

Now that you have been introduced to the key guidelines you’ll refer to often when conducting accessibility reviews, it will be necessary for you to expand on your understanding of WCAG 2.0 by eventually reading through the full specification (if possible, along with reading this book).

To become comfortable with WCAG 2.0 and its associated documentation, try this Scavenger Hunt challenge. Below is a list of barriers that you’ll likely see on many websites. For each barrier, find a relevant guideline and match a sufficient technique (with its ID) to remove the barrier. How to Meet WCAG 2.0 is a good reference.

Happy hunting!
