This short book provides a practical introduction to HTML5. HTML (HyperText Markup Language) is the predominant language of web pages. Originally developed as a way to describe and share scientific papers, HTML is now used to mark up all sorts of documents and create visual interfaces for browser-based software. With HTML5, however, HTML has become as much an of API for developing browser-based software as it is a markup language. In this book, we’ll talk about the history of HTML and HTML5 and explore its new features.
