Adobe helps develop fluid CSS modules that adapt to various viewing experiences. HTML5 and CSS3 have brought to the design world not only new techniques and an easier or more manageable code but also the chance to create features for a website that were previously available with flash, javascript or some pretty hardcore designing. CSS Regions is a module that builds on the column-based layout options now available in CSS3 to enable front-end developers to flow text across different columns (or “regions”) on a page. This allows for more dynamic page designs, which can shapeshift to fit different devices and device orientations on-the-fly.

Another improvement to CSS proposed by Adobe is called Exclusions, which lets developers flow text into a non-rectangluar shape, or to wrap it around graphics on the screen, much like what’s been possible in desktop publishing for decades. Check out the video below for examples of these new standards at work.

Space CaCSS - Animated CSS3 background patterns. Let’s get trippy. How does it work? The basic technique is to use a CSS3 repeating-radial-gradient as a background and animate it by changing its background-size. That’s all what’s needed in the second example. Pretty hypnotic. If you want more variations you can use a second gradient with a different background-size. Or add a second animation for the background-position with a different timing. That makes it possible to create a somewhat random looking motion like in the last example (orange).
