Web Browsers Used in This Book

We tested all of the code in the most current versions of seven popular browsers—five for the desktop (Chrome, Internet Explorer, Firefox, Opera and Safari) and two for mobile devices (iPhone and Android). HTML5 and CSS3 are evolving and the final standards have not been approved yet. The browser vendors are selectively implementing features that are likely to become a part of the standards. Some vendors have higher levels of feature compliance than others. With each new version of the browsers, the trend has been to significantly increase the amount of functionality that’s been implemented. The HTML5 test site (html5test.com) measures how well each browser supports the pending standards and specifications. You can view test scores and see which features are supported by each browser. You can also check sites such as http://caniuse.com/ for a list of features covered by each browser. Not every document in this book will render properly in each browser. Instead of choosing only capabilities that exist universally, we demonstrate exciting new features in whatever browser handles the new functionality best. As you read this book, run each example in multiple web browsers so you can view and interact with it as it was originally intended. And remember, things are changing quickly, so a browser that did not support a feature when we wrote the book could support it when you read the book.
