Your Web Accessibility Toolkit
Throughout the content, we’ve also identified elements that should be added to the Web Accessibility Toolkit that you will be assembling while reading the book. These elements will include links to resource documents and online tools used during activities, as well as software or browser plugins that you may need to install. These will be identified in a green Toolkit box, like the one below.

The W3C have defined four principles that define accessible web content. To be accessible, web content must be perceivable, operable, understandable, and robust (POUR).
Under each principle are guidelines that detail how each principle can be addressed.
Accompanying each WCAG guideline are success criteria that provide a detailed checklist of true or false statements for you to check your content against.
Here are some tips that will help you manage your time and get the most out of the book.
- Set up a folder in your browser’s bookmarks/favourites area before reading, so that you can add links to tools and resources gathered for your Web Accessibility Toolkit.
- Set regular study periods at the start of the book and stick to them.
- You can skip ahead if you are able.
- Before starting a chapter, scan through it first to gather a general understanding of the topics covered.
