Cascading style sheets apply things such as borders, spacing between paragraphs, headings or images, control of font faces or font colors, background colors and images, textual effects such as underlined or strike-through text, layering, positioning, and a number of other presentational effects. CSS controls the presentational aspects of a web page's design, whereas HTML, XHTML, or XML controls the structure of a web page, which means little more than determining that certain text is a heading, other text is a paragraph, still other text is a list of hyperlinks, and so on.
CSS and XHTML allow a web document to be presented with less code, resulting in a significantly smaller file size and greatly increased ease of maintenance. CSS also enables the presentation of a web document to be centralized, which allows for the look and feel of an entire website to be written and centralized in one or a few simple documents, which makes updating a website a breeze.
With only a few simple edits to a single document, the look and feel of an entire website can be completely changed. You can also greatly reduce the amount of physical bandwidth and hard disk space required, resulting in immediate long-term benefits for any website.
This second edition of Beginning CSS features a near-complete overhaul of the content from the first edition. Changes based on what readers had to say about the first edition helped to create the most comprehensive introduction on CSS available on the market.
Throughout this book, you see CSS broken down into simple examples that focus on a single concept at a time. This allows you to better understand how and why something works, since you aren't presented with a lot of irrelevant code, and you can better see the bits and pieces that come together that make something work.
While these examples may not be particularly pretty, they are extremely valuable learning tools that will help you master cascading style sheets.
To enhance the learning experience, most of the source code examples are presented in syntax-colored code, a special feature in this book. Syntax coloring is a feature that you commonly see in fancy development software, such as Zend Studio used to develop PHP , or Microsoft's Visual Studio used to develop ASP, C , and so on , and other software used by professional programmers every day.
Syntax coloring is used in these software suites to make programming easier and more intuitive, and it offers tremendous benefits in teaching as well. It allows you to see what the different bits and pieces are in source code, since each of the different bits and pieces has a different coloring to identify its purpose. It helps you to distinguish the building blocks of code more easily, and if you use similar development software to write your CSS and HTML documents, you'll also find that you make fewer mistakes and typos, since syntax coloring also helps you to write code that is more bug free.
Many of the source code examples feature annotations to highlight important, not-to-be-forgotten bits of information, and to visually point out concepts that are discussed in the surrounding text. This edition also features every screenshot from a browser in color, a first for Wrox. Presenting the browser screenshots in color makes it easier for you to compare your results with what you see in the book.
This book also approaches CSS development from a browser-neutral point of view, and provides all the information that you need to get a good healthy start on professional cross-browser, cross-platform website design with IE 6, IE 7, Firefox 2, Opera 9, and Safari 2, which will allow you to reach over 99 percent of the web browsing public.
You also see comprehensive coverage of bugs, and workarounds for the IE 6 and IE 7 web browsers. This book covers many of the hacks and nonstandard workarounds that you may need to develop compatible CSS content in IE 6.
IE 7 features many great improvements to CSS support, and though they are much fewer than its predecessor, you still need a few tricks to make your web page shine in Microsoft's latest browser. It covers the workarounds that you'll need to make your pages work just as well in IE 7 as they do in all the other popular browsers. You'll see that Mac browsers are equally represented among their Windows brethren.
Whom Is This Book For? This book's primary audience is anyone seeking to learn how to use cascading style sheets to present web documents. Because cascading style sheets are used to control the presentational layout of a web document, people from backgrounds in art, graphic design, or those who prepare print layouts for publishing will feel at home using CSS. Each lesson in this full-color book has been methodically revised to be more concise and efficient, making your learning experience as productive as possible.
This new edition of a perennial classic responds to that need and gets you quickly up to speed on using CSS to create appealing web sites in a professional way. Completely updated with new examples, this full-color book has been carefully revised based on reader input and now provides an even more concise and streamlined introduction to CSS. Veteran authors Ian Pouncey and Richard York cover how to write CSS from scratch like a professional, and discuss the many improvements to CSS that have emerged since the previous edition.
