HTML5 is a natural evolution of earlier versions of HTML and strives to reflect the needs of both current and future Web sites. It inherits the vast majority of features from its predecessors, meaning that if you coded HTML before HTML5 came on the scene, you already know a lot of HTML5. This also means that much of HTML5 works in both old and new browsers; being backward compatible is a key design principle of HTML5 . HTML5 also adds a bevy of new features. Many are straightforward, such as additional elements (article, section, figure, and many more) that are used to describe content. Others are quite complex and aid in creating powerful Web applications. You’ll need to have a firm grasp of creating Web pages before you can graduate to the more complicated features that HTML5 provides. HTML5 also introduces native audio and video playback to your Web pages, which the book also covers.
