CSS 3 Reccomendations
I've been looking at the CSS 3 Reccomendations in progress. There are some really neat things that are part of these reccomendations. One interesting thing is the writing-mode property, which changes the way text flows on the page. This property will be very helpful in rendering languages such as Arabic, Hebrew and some east Asian language. It also can help with making some really neat layouts. Unfortunately, it is only supported in Internet Explorer 5.5 and higher right now. If you want to see a demo check out the “On the BLeading Edge” section of this site.
Another interesting part of CSS 3 are the additions to the paged-media section. There are pieces of the new specification which allow you to control running headers and footers, and page numbers.
