CSS Regions by Adobe are part of WebKit now
Back in November we already mentioned that Adobe decided to contribute to WebKit, an open source web browser engine used by Google Chrome, Safari, Midori etc. Merely two days ago Adobe committed the first changes into main Webkit's development tree that add some new features.
These features are two new additions called CSS Regions and CSS Exclusions. They allow flowing text into arbitrary shapes, creating multicolumn text blocks and flowing text from frame into frame. Here are several illustrations provided by Adobe Systems.
Text flow into shapes:
Tetx flow from block to block:
What Adobe actually does is an attempt to bring traditional book and magazine layouts to the Web, as well as to tablets like iPad that rely on W3C standards for rich dynamic content support. At the same time the company has been working on getting these additions to upstream CSS3 specification. Their specification on these new features was published in March this year, and the current drafts are at dev.w3c.org already: CSS Regions Module, CSS Exclusions Module.
A month ago Adobe Systems already released their custom WebKit based browser targeted at early adopters of CSS Regions. Availability of both CSS Regions and CSS Exclusions in upstream WebKit, however, is likely to boost adoption of both new technologies.
So far there seem to be no public statements regarding CSS Regions support by Opera or Mozilla Foundation teams.
