Getting the Most Out of This Book

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.

Toolkit

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:

Toolkit: Provides useful tools and resources for your future reference.

Key Points

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.

Key Point: Essential information and interesting points.

Try This

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.

Try This: Usually a quick activity to help you understand a topic being discussed.

Suggested Reading

Links listed in these Suggested Reading boxes act more as references than readings. At a minimum, scan through these documents to understand what they contain and refer back to them when you encounter scenarios where WAI-ARIA could or should be used.
Suggested Reading: Links to various web resources for optional reading on the topics being discussed.

Activity Elements

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.

Activity Element: A brief description of each section of an activity.

Self-Tests

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.

Try This: Skip ahead to the end of the book and read through the Book Recap for a high-level summary of the topics covered in the book.
