The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Regions Module Level 1. The CSS Regions module allows content from one or more elements to flow through one or more boxes called CSS Regions, fragmented as defined in CSS3-BREAK. This module also defines CSSOM to expose both the inputs and outputs of this fragmentation. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Learn more about the Style Activity.
