W3C Recommendation 12-May-1998 This version: http://www.w3.org/TR/1998/REC-CSS2-19980512 Latest version:
1.1 Reading the specification This specification has been written with two types of readers in mind: CSS authors and CSS implementors. We hope the specification will provide authors with the tools they need to write efficient, attractive, and accessible documents, without overexposing them to CSS's implementation details. Implementors, however, should find all they need to build conforming user agents . The specification begins with a general presentation of CSS and becomes more and more technical and specific towards the end.
The other day my fellow co-worker, Cameron , and I were discussing what the best way to style the hr tag? I usually try to use a div if I just need a line for presentation. But what if I need to style an hr that is used on an existing site.

Apart from Floats , the CSS Specificity is one of the most difficult concepts to grasp in Cascading Stylesheets. The different weight of selectors is usually the reason why your CSS-rules don’t apply to some elements, although you think they should have. In order to minimize the time for bug hunting you need to understand, how browsers interpret your code. And to understand that, you need to have a firm understanding on how specificity works . In most cases such problems are caused by the simple fact that somewhere among your CSS-rules you’ve defined a more specific selector.
The concept of floats is probably one of the most unintuitive concepts in CSS. Floats are often misunderstood and blamed for floating all the context around it, causing readability and usability problems. However, the reason for these problems isn’t the theory itself, but the way the theory is interpreted – by developers and browsers. Still, if you take a closer look at the float theory, you’ll find out out that it isn’t that complex as it appears to be. Most related problems are caused by the older versions of (take a guess) Internet Explorer. If you know the bugs, you can control the way information is presented in a more sophisticated, profound way.
Sometimes being a web-developer is just damn hard. Particularly coding is often responsible for slowing down our workflow, reducing the quality of our work and sleepless nights with pizza and coffee laying around the laptop. Reason: with a number of incompatibility issues and quite creative rendering engines it sometimes takes too much time to find a workaround for some problem without addressing browsers with quirky hacks. And that’s where ready-to-use solutions developed by other designers come in handy. One year ago we’ve published the post with 53 CSS-Techniques You Couldn’t Live Without where we provided references to the most useful CSS-techniques which are often used in almost every project. Over the last year we’ve been observing what’s happening with the CSS-based web-development, and we collected most useful CSS-techniques we’ve stumbled upon — for us and for our readers.
