YUI 2.8: Learning the Library

Overview of this book

The YUI Library is a set of utilities and controls written in JavaScript for building Rich Internet Applications, across all major browsers and independently of any server technology. There's a lot of functionality baked into YUI, but getting to and understanding that functionality is not for the faint of heart. This book gives you a clear picture of YUI through a step-by-step approach, packed with lots of examples.YUI 2.8: Learning the Library covers all released (non-beta) components of the YUI 2.8 Library in detail with plenty of working examples, looking at the classes that make up each component and the properties and methods that can be used. It includes a series of practical examples to reinforce how each component should/can be used, showing its use to create complex, fully featured, cross-browser, Web 2.0 user interfaces. It has been updated from its first edition with the addition of several chapters covering several new controls and enriched with lots of experience of using them.You will learn to create a number of powerful JavaScript controls that can be used straightaway in your own applications. Besides giving you a deep understanding of the YUI library, this book will expand your knowledge of object-oriented JavaScript programming, as well as strengthen your understanding of the DOM and CSS. The final chapter describes many of the tools available to assist you the developer in debugging, maintaining, and ensuring the best quality in your code. In this new edition, all the examples have been updated to use the most recent coding practices and style and new ones added to cover newer components. Since the basic documentation for the library is available online, the focus is on providing insight and experience.The authors take the reader from beginner to advanced-level YUI usage and understanding.

Preface

Tidying up text with fonts.css


The next CSS Tool, fonts.css, is provided so that you can easily standardize all of your text to a single font-face, font-size, and line-height. In terms of the amount of actual code, this file is tiny; in fact much smaller than the Reset CSS Tool we looked at earlier, providing just five rules in total.

It standardizes all rendered text on the page to the Arial font, except for text within <pre> and <code> tags, which instead use the monospace typeface.

The first rule targets the <body> tag and sets the font-family attribute to arial, helvetica, clean, or sans-serif. This provides a clear font degradation path; if browsers or operating systems don't have Arial installed or for some reason can't display it, the platform tries Helvetica next, and so on, right down to sans-serif if necessary (although it's unlikely that the browser would need to travel all the way down to the end of the degradation path).

This is also important for Unicode...
