Complete CSS Guide

When Cascading Style Sheets were introduced in late 1996, they represented an exciting new opportunity. They enabled much more sophisticated page design (typography and layout) than web developers had been used to, and they helped manage the complex tasks of developing and maintaining sites, and keeping them up to date. They also greatly simplified the process of making web pages accessible to as many people as possible, regardless of the device they use to read a page, and regardless of any disability they might have.

Since then, much about the web has changed. It's hard to believe now but in late 1996, Netscape Navigator was the browser of choice for the majority of web users. Internet Explorer from Microsoft lagged far behind in terms of features, performance, and number of users. Web browsing was something you did on a PC or Mac. HTML was not a single standard which was well adhered to, but a tangle of competing versions, with proprietary extensions. The dotcom boom was still gaining momentum, and the bust was just a twinkle in the naysayers' eyes.
Now, Internet Explorer dominates the browser scene even more than Netscape did back then. Browsers are built into mobile phones and people browse from television based systems, even games consoles. HTML has become a widely adhered to standard, and lots of those old proprietary extensions have either gone the way of all flesh, or become part of the standard. And slowly, slowly, intransigence, reluctance and skepticism towards CSS is fading away. Cascading style sheets are becoming a solid, well supported and easy to use technology for creating the appearance of web pages.

Many (internet) years ago, we put together a quite straightforward guide to getting up to speed with CSS. In time it's grown to accommodate changes in our knowledge and in CSS itself. This single guide has grown into a whole website, the "House of Style", with articles, tutorials, reference materials .But people still seem to get a lot of value out of this guide so yet again we've dusted it off and updated it to take into account what we've learned lately, some recent changes to CSS, and current levels of browser support. The third edition of the guide incorporated browser support details and added a section on real world issues. This fourth edition brings the guide inline with the W3C's January 2003 revision of the specification, CSS 2.1.
