CSS offers various kinds of benefits For example, a single style sheet can cascade its effects through all the pages in a Web site One side of effect of this is that if you decide to change your site s default body font from Arial to Times New Roman, you need make that change only once within the style sheet, rather than hunting down all the attributes throughout the entire set of HTML code files that make up your site Another benefit of using CSS is that the style sheet only needs to be downloaded once to the user s computer Thereafter, it s called up from a local cache, resulting in smaller HTML pages Your Web pages load faster into the user s browser still a major consideration for the 60 percent or so of online Americans who still don t have broadband highspeed Internet connections If you ve already worked with CSS, this book will sharpen your skills and show you lots of new techniques You ll take your Web design to the next level If you re new to CSS, you re in the right place: You ll find just what you need here to build unified, attractive, inviting Web sites This book shows you, the CSS designer, how best to exploit, expand, administer, and write code for Web pages The book covers all the essentials of CSS,

CSS has been available for several years, but, like DHTML (dynamic HTML for Web page animation effects), CSS languished because of the browser wars Basically, Netscape s Navigator and Microsoft s Internet Explorer attempted to enforce different, proprietary standards Now that Netscape is all but dead in the marketplace and standards have become relatively stable because of the dominance of Internet Explorer, CSS has become a major technology for the creation and design of first-rate Web sites Some incompatibility issues still exist, but this book deals with them only occasionally Why Because often you need not write complex, workaround code to take into account an audience so small that, practically speaking, many Web pages simply ignore them That said, I realize that some designers are forced to deal with browser compatibility issues, so I do explore the topic in some depth in 17 You see how to detect which browser and version the user has and how to take appropriate steps to deal with it in your Web page code I also tell you where to find the best compatibility charts online; how to see what your page looks like and test its behavior in non-compliant browsers; and how to automatically redirect a browser to a different Web page or Web site if that browser can t deal with your CSS code A few years ago, people were moving from Netscape to Internet Explorer, but a large percent of your Web site s audience was still using Netscape You had to write CSS (and HTML and scripting) that worked effectively in both browsers

That s simply no longer true The migration is over; Netscape is merely a ghost wandering the halls of the computer history museums Most CSS books waste lots of space on compatibility issues I ve decided to greatly reduce coverage of that topic for precisely the same reason that today s newspapers infrequently devote space to the Gulf War of 1991 That war s over Same with Netscape and the other, minor browsers like Opera that have a small user base History and popular opinion has elected Internet Explorer (IE) as the standard who are we to argue One exception is Mozilla Firefox, which is coming out of left field and could eventually challenge Internet Explorer s dominance in the browser arena Firefox is an open source in other words, no charge piece of software Of course, Internet Explorer is also sometimes described as free True, it comes free with Windows, but as we all know, that s not precisely the same as no charge You do buy Windows, and its browser is a feature of Windows that you get bundled into the operating system Another meaning of open source is that the code, the programming underlying the Firefox browser, is available to anyone Lots of good programmers are writing interesting plug-ins and modifications that you can add to Firefox to give it new features Firefox is fast, sleek, and overall pretty stable In fact, it s not under constant attack by hackers, as is IE There are two reasons for this: not too many people are using Firefox (yet), so the payoff of using it to spread viruses is rather poor Second, virus authors are frequently in sympathy with the ideals of the open source software community, and, shall we say, less inclined to appreciate Microsoft So, watch out, IE Firefox, or something similar, could eventually gain market share and, possibly, eventually become the browser standard But for now, more than 95 percent of browser users are looking at your Web page through IE, so you can generally ignore the problems that arise when you try to make your CSS code work with all possible browsers and all possible versions of those browsers IE is likely to continue to dominate for at least the next few years Just relax and assume that your Web page visitors are either using IE, or are accustomed to the penalties for sticking with a fringe browser But if you must face the compatibility issue, take a look at 17
