This demo for this CSS3 style is not yet prepared. Rather than waiting for it, by all means visit this CSS3.info page, which describes and demos this CSS3 style. Surprisingly, this basic effect from the CSS2 specification has only been implemented in Safari/WebKit. The effect lets you add a shadow to text, much as you can in any Mac OS X Cocoa application that has an editable document.

Moving right along, Apple has foreseen a need that hasn't yet made it formally into the W3C specification for CSS3, though I'll be surprised if it doesn't sooner or later. In addition to adding shadow to textual elements, it's commonly desirable to add strokes to text glyphs as well. That's what this implementation does. This demo for this CSS3 style is not yet prepared, but you can visit the Surfin' Safari blog to read more about it in the meantime.

With transforms and animations, Apple has really upped the ante on what CSS can do on its own---without JavaScript. As stated on the WebKit blog last October,

WebKit now has rudimentary support for specifying transforms through CSS. Boxes can be scaled, rotated, skewed and translated. The current nightly builds support affine transformations.

The WebKit article has some brief documentation, and you can also read about this development in Apple's draft specification to the W3C. If you want to see a little demo of what this feature can do, check out this page.

According to WebKit's draft submission of this spec to the W3C, Transitions are the primary proposed CSS 3.0 class, with Animations described as an extension. Whatever the technical language, these new CSS features are truly awesome additions to the web designer's toolkit. The introductory article on the WebKit blog has some excellent demos of Transitions/Animations, as well as a good summary of what they are and how they work.

This feature is so new---it just came out today (April 14, 2008)---that I have only begun to consider the implications. Needless to say, a part of me went "Yipee!" at the thought, and I look forward to trying it out. So far, all I know is what's on the WebKit blog article that describes CSS Gradients and which provides a series of demos for them. Enjoy!
