Some of these CSS3 previews show just how far behind Internet Explorer is when it comes to the latest and greatest in CSS3. Nice features such as HSLA colours are already being implemented by other browsers!
HSLA colours are a very nice thing indeed. Instead of defining a colour as Red, Green and Blue, web designers of the future will be able to choose Hue, Saturation and Lightness, as well as Alpha, an opacity value.
That means it will be much easier to guess-pick colours when you’re coding. Also, making a colour semitransparent will be a very nice possibility for backgrounds. (No more semitransparent 1px png graphics!)
Then we have rounded borders, which is already being used around the web, since it degrades nicely (into square corners).
Another promising feature of CSS3 is columns. Currently, only Mozilla browsers (Firefox 1.5+) support this in any way. The idea is that you will be able to set a column width as well as spacing, and the browser will calculate how many columns to fit across the screen. Alternatively, you can define how many columns you want, and the browser will adjust their width to fit the space provided. A List Apart has a very nice article on the subject.
If you’re really intersted, have a look at what the W3C are working on right now, the different modules and their specs. CSS3 is still work in progress, so only a couple of the modules are even close to the recommended status. (I.e.
implement now! status.
