Whenever you read or interact with a page in your browser, chances are it’s an HTML document. 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 in- terfaces for browser-based software. With HTML5, however, HTML has become as much an of API (Application Pro- cessing Interface) 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 some of its new features. Who Should Read This Book Although this book is meant for HTML5 beginners, its brevity means that it can’t be comprehensive. As a result, we do assume some prior knowledge of HTML. If you are completely new to web development, SitePoint’s Build Your Own Website Using HTML and CSS may be a better book for you. Conventions Used You’ll notice that we’ve used certain typographic and layout styles throughout this book to signify different types of information. Look out for the following items. Code Samples Code in this book will be displayed using a fixed-width font, like so: <h1>A Perfect Summer's Day</h1> <p>It was a lovely day for a walk in the park. The birds were singing and the kids were all back at school.</p> If the code is to be found in the book’s code archive, the name of the file will appear at the top of the program listing, like this: xiv example.css .footer { background-color: #CCC; border-top: 1px solid #333; } If only part of the file is displayed, this is indicated by the word excerpt: example.css (excerpt) border-top: 1px solid #333; If additional code is to be inserted into an existing example, the new code will be displayed in bold: function animate() { new_variable = "Hello"; } Also, where existing code is required for context, rather than repeat all the code, a ⋮ will be displayed: function animate() { ⋮ return new_variable; } Some lines of code are intended to be entered on one line, but we’ve had to wrap them because of page constraints. A ➥ indicates a line break that exists for formatting purposes only, and should be ignored.

Tips will give you helpful little pointers. xv Ahem, Excuse Me … Notes are useful asides that are related—but not critical—to the topic at hand. Think of them as extra tidbits of information. Make Sure You Always … … pay attention to these important points. Watch Out! Warnings will highlight any gotchas that are likely to trip you up along the way.

Tools You’ll Need All you’ll need to develop HTML5 documents is a text editor for writing, and a browser for viewing your work. Don't use word processing software. Those programs are made for writing documents, not for programming. Instead, you’ll need software that can read and write plain text. xvi If you’re a Windows user, try Notepad++1, a free and open-source text editor. Mac OS X users may want to try TextWrangler2 by Bare Bones software. It's free, but not open source. Brackets3 is another option for Windows and Mac users. Linux users can use gEdit, which is bundled with Ubuntu Linux, or try the free and open source Bluefish4. Paid software options are also available, and are sometimes more refined than free and open-source options. You'll also need at least one browser that supports HTML5 in order to make use of the examples in this book. Make sure you’re using the latest version of Google Chrome, Microsoft Internet Explorer, Apple Safari, Opera, or Mozilla Firefox available for your operating system. Internet Explorer and Safari are bundled with Microsoft Windows and Mac OS X, respectively. Other browsers may be downloaded from their company web sites. Do You Want to Keep Learning?
