When I first started learning DHTML, there were two kinds of books on the market: overly simplified, cutesy books that were appropriate for technophobe junior high schoolers, and huge reference tomes that had their own gravity. But nothing really taught me how to build pages for real clients using CSS and DHMTL.
This book will guide you through CSS (also called "style-sheets") and DHTML, using examples and techniques taken straight from my experience as a Web designer and programmer. I'll start off with basic concepts and simple examples and work up to more sophisticated effects and functionality.
Who This Book Is For
How This Book Is Laid Out
The first code-heavy chapter covers CSS in all of its useful forms with a myriad of examples. The rest of the chapters focus on DHTML by presenting a real-world task and walking you through it step by step. All of the examples are for one of two fictional companies: Shelley Biotechnologies or Stitch, an online fashion magazine (like every other book in this series).
The exercises and examples are designed to give you a solid, market-ready foundation in DHTML and enough expertise in practical solutions to carry you through 90% of the DHTML projects you'll do. You'll find there's often more than one way to accomplish a feat in DHTML, which is fine—there is no right or wrong in coding.
All of the code, images, and working examples are available for download and viewing on www.wire-man.com/dhtml2 and www.phptr.com/essential.
Special for Second Edition
I am delighted to be able to write a second edition of this book. I've received hundreds of emails from readers of the first edition—some good, some bad. I have implemented many of the suggested changes, and kept the things people liked. I think the book is much stronger for it. If you have any questions or comments, feel free to drop me a line at firstname.lastname@example.org—I'd love to hear from you.
○ What Are CSS and DHTML?
CSS stands for "cascading stylesheets," but we'll just be calling them "stylesheets" from now on. For all practical purposes, stylesheets are as much a part of HTML as the <img>and <table> tags. Adding stylesheet information to a page is just a matter of typing in some extra code. There's nothing fancy about it.
Placing stylesheet information into a Web page lets you set certain aspects of that HTML page. For example, your stylesheet could say, "Make all of the text in this Web page 16 point bold Arial," or "There's a layer called 'banner' and it's located at 60 pixels over and 90 pixels down," or even "When the <b> tag is used, make that text both bold and italic." CSS is a standard created by the World Wide Web Consortium, the same folks who define exactly what HTML is. There are several versions of CSS (the third version, CSS3, is being worked on right now). The browsers all implement variations of the first two versions, CSS1 and CSS2. You don't need to be concerned about them in this book—we'll look at what works without worrying about which version it is.
○ What Can CSS Do?
Stylesheets can do three things:
::.Set the font of text on a page
::. Define a layer and position it on the page
::. Modify HTML tags
If you decide to use stylesheets to set your page's fonts, you can define different classes of fonts, like "headlineText" or "footerText" or "mainBodyText," and use different fonts for all three. This may not sound exciting, but if used properly, this can save you hours and hours that you'd otherwise spend using the nasty and decrepit <font>tag.
○ When Is CSS Really Used?
Stylesheets are really used only for the first two items above: setting fonts and positioning layers. You can use stylesheets to modify HTML tags, but I (and most other Web developers) haven't found that to be very useful. It tends to confuse more than to facilitate. So, I'll be concentrating mostly on using stylesheets to set fonts and position layers throughout this book. I'll show you how to modify tags, but there won't be a lot of examples—that would be like showing you the proper way to ride a bicycle underwater. I'll show you how to do it, but an extended tour wouldn't serve any real purpose.
○ What Is DHTML?
○ What Can DHTML Do?
DHTML can do all sorts of really interesting and fun things. You can create little games, sliding pop-up menus, draggable images, interactive quizzes, and the like. Internet Explorer (IE), especially, has all sorts of great extensions that will let you get pretty creative. There's no end to the things you can do.
○ The Limitations of DHTML
I bring up this story as a potential warning: If you get really fancy with DHTML, you will pay. Development time to make your code work on the various browsers and platforms will take way longer than it should. If you think you're done, look at your page on a Macintosh running IE 4.5.
Everything in this book is fully cross-browser and cross-platform. In fact, I'm ignoring everything that's Netscape-specific or IE-specific. As of this writing, Netscape hasn't completely lost the browser war yet, so Netscape users must still be considered. Also, Netscape 6 is less popular than expected, so Netscape 4.x users must still be considered and coded for.
○ When to Use DHTML
To be honest, I only use DHTML to make layers appear and disappear, and for simple animation. However, not everyone has such pedestrian ambitions for their DHTML, so you'll find examples that go beyond those few uses in this book. In fact, I expect to see a lot more DHTML on the Web fairly soon, now that almost everyone has Netscape 4.7+ and IE 5.x. All the browser metrics I've seen indicate that at least 95% of Web surfers have a 4.0+ browser.
When you start to code your own DHTML, start small and simple. It's easy to make large promises to a client, and as a brilliant programmer, I'm sure you'll deliver on them, but you'll save yourself a lot of heartache and late nights if you build your pages in incremental phases.
