Accessibility is not just about addressing specific disabilities, but making sure as many people as possible have access to the same information.

Accessibility is not just about addressing specific disabilities, but making sure as many people as possible have access to the same information. There’s rarely a good reason to lock people out when openness is a foundational principle of the web.
Web accessibility is quite a large topic — far too large to fit into a small book. So, what will this book cover? Though we shall encounter visual design challenges, deal with performance issues, and adopt progressive enhancement — all of which are accessibility concerns — the underlying theme of this book is about making the interactivity of web applications include keyboard and screen reader users.
Starting with defining simple button controls and moving on to create reusable, accessible widgets, this book is about making interactions possible and meaningful for those who suffer from cognitive and motor impairments, as well as users who experience a range of vision impairments. However, the lessons learned from addressing the specific requirements of those using assistive technologies or consuming information in unusual ways can be applied to enrich the web for everyone. We all win.
It can seem that way, but no. You see, web standards are all about agreement. It’s only through agreement that things can be made to work and behave in ways that are predictable for the greatest number of people. By designating certain behaviors to the <button> element, browser vendors can agree on how the element should be rendered and how it should behave.
This way, authors like you and I will know which element to code if we want to elicit these behaviors. We work with the browser vendors to make our users’ lives easier. By convention, they know what they’re getting when they encounter a button.”
“You won’t get far on the web these days without stumbling on some sort of tabbed interface. You know the kind of thing: a line of tabs, like those used in a filing cabinet, with each corresponding to their own pane or panel of content. It’s a popular pattern because it allows users to browse and switch between content, excluding from view anything they’re not interested in.
It has been our goal to make the book as practical and useful as possible. We’ve been honored to receive very positive reviews from people making websites on small and large scale.
“Heydon has written a truly awesome book here! He gets right to the stuff that developers love most: Coding. He provides concise context for those not too familiar with accessibility yet, but doesn’t scare devs with legal stuff. He concentrates on the positive impact aspects aside those legal reqs and thus makes sure the book is fun to read! The examples are not some abstract form of things one will never encounter anyway. On the contrary: They are examples you can integrate right into the web applications you develop and thereby make sure more potential customers than you can even think of at the moment will enjoy using your work! If you’ve been looking for a modern up-to-date easy introduction or refreshment to/of accessibility coding skills, this is the book to purchase!”— Marco Hengstenberg, Pixelpusher & Websitewrangler
“Having read this book over the last couple of days I am in no doubt as to what all the developers at work are getting for Xmas. Its a fantastic read that sets out the reasons for WAI ARIA in a really easy to read and understand manner. the concepts are well explained and the code snippets are an awesome compliment to the well delivered prose. Its both funny and educational at the same time and I would highly recommend it to any developer who is keen to broaden his skill set. Fantastic job Heydon and I look forward to the sequel :)”— Hamish Mackenzie, Global Accessibility Manager
“This book is a little gem. There are many useful and well coded examples that cover common accessible design patterns that many more conscious web developers will find downright essential in their day to day work.— Joshue O Connor, editor of the new WCAG 2.1 accessibility standard
Heydon does a great job of helping the reader understand an inclusive design approach and the often rather granular ‘step by step’ process that accessible web applications need in order to be accessible.
I especially found the section on focus management (which is a complex subject) really useful, with nice short code snippets but that is certainly not the only area that surprised.
Heydon has a warm writing style and nicely walks the line between the need for supporting legacy user agents/AT and the cutting edge. Finally, he also helps to remind us of how exciting implementing accessible and inclusive design in our projects can be - with its many inherent challenges and rewards.”
