I just noticed the post on Ben Forta's blog about CSS regions, which has been submitted to the W3C as a working draft. The video demonstrates what an excellent concept regions are; content flows between columns automatically as a page is resized, and not only does content flow within irregular shapes, such as within diamonds or around curved background photos, but it also happens as the page is resized or as the page scrolls. Hallelujah! We've been waiting for this to be implemented for the last decade! I can only hope that it gets approved and implemented by browser makers soon.
