Introduction > Conventions Used Throughout this Book

Conventions Used Throughout this Book

This book uses a few terms that are worth noting at the outset.

  • W3C refers to the World Wide Web Consortium, the organization that creates the official standards and specifications of the web, including CSS3.

  • IE refers to the Windows Internet Explorer browser. IE 8 and earlier means IE 8, 7, and 6.

  • Webkit-based browsers means Safari (both on desktop and on mobile devices), Chrome, and any other browsers that use a recent version of the Webkit browser-rendering engine.

  • Occasionally, you’ll see a reference to “all browsers.” This means all browsers that are in significant use today, not literally every single obscure browser that may have a fractional piece of market share.

All of the exercises in this book are written in HTML5 markup. However, all that means in this case is that I’ve used the short and sweet HTML5 doctype, <!DOCTYPE html>, as well as the shorter meta character encoding, style, and script tags. I haven’t included any of the new elements that HTML5 introduces, such as section or article, so the pages will work without any trouble in IE 8 and earlier, but you’re welcome to change the markup for your own pages in whatever way you like. All the exercises will also work in HTML 4.01 or XHTML 1.

All CSS examples shown should be placed in an external style sheet or in the head of an HTML or XHTML document. The exercise files have their CSS contained in the head of the page, for ease of editing, but it’s best to move that CSS to an external style sheet for actual production files.

Some code examples will contain characters or lines colored teal-blue. This indicates that content has been added or changed since the last time you saw that same code snippet, or, in a new code snippet, that there is a particular part that you need to focus on. In some cases. you’ll see a ¬ character at the beginning of a line of code, indicating that the text has had to wrap to a new line within the confines of the layout of this book—but this doesn’t mean you have to break the line there.

Each property or selector introduced in this book has a “lowdown” sidebar providing a brief overview of its syntax, behavior, and use cases. Not every detail of syntax could be included, of course, but the most essential information you need is there for quick reference. I’ve also provided a link to whichever CSS3 module the property or selector is a part of on the W3C site so you can refer to the full specification when needed.
