We highly recommend reading this book online. While the book is available for download in various formats (ePub, HTML, and PDF), the interactive elements in the readings and activities are best viewed here in Pressbooks.
Throughout the book, you’ll see the various coloured boxes described below to help you organize how you engage with the content.
Throughout the book, we identify items that should be added to your WAI-ARIA Developer Toolkit, which you will collect during the course of the book. These items will include links to resource documents and online tools used during development 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 following:
Important or notable information is highlighted and labelled in Key Point boxes such as the one that follows. These will include “must know” information, as well as less obvious considerations and interesting points.
Brief activities are highlighted in in the Try This boxes. These activities are designed to get you thinking or give you firsthand experience with something you’ve just read about.
When the widget coding activities are introduced in Chapter 4, each of the elements in the example activity are described using the Activity Element box.
The first few chapters include Self-Tests, which will help reinforce key topics discussed in a unit. For questions that have multiple answers, be sure to select all the correct answers and none of incorrect answers in order for the question to be marked “correct.” Multiple answer questions can be challenging, and they typically require a thorough understanding of the topic in question to answer correctly. Questions will only reference topics covered in the book itself. They will not test your knowledge of content referred to on external resource sites that may be linked from the book.
