HTML5: Up and Running

What is HTML5? HTML5 is the next generation of HTML, superseding HTML 4.01, XHTML 1.0, and XHTML 1.1. HTML5 provides new features that are necessary for modern web applications. It also standardizes many features of the web platform that web developers have been using for years, but that has never been vetted or documented by a standards committee. (Would it surprise you to learn that the Window object has never been formally documented? In addition to the new features, HTML5 is the first attempt to formally document many of the “de facto” standards that web browsers have supported for years.)

Like its predecessors, HTML5 is designed to be cross-platform. You don’t need to be running Windows or Mac OS X or Linux or Multics or any particular operating system in order to take advantage of HTML5. The only thing you do need is a modern web
browser. There are modern web browsers available for free for all major operating systems. You may already have a web browser that supports certain HTML5 features. The latest versions of Apple Safari, Google Chrome, Mozilla Firefox, and Opera all support many HTML5 features. (You’ll find more detailed browser compatibility tables throughout this book.) The mobile web browsers that come preinstalled on iPhones, iPads, and Android phones all have excellent support for HTML5. Even Microsoft has
announced that the upcoming Version 9 of Internet Explorer will support some HTML5 functionality.
