The CSS Working Group has published CSS Writing Modes Level 3 as a W3C Recommendation.

This CSS module defines CSS support for various international writing modes and their combinations, including left-to-right and right-to-left text ordering as well as horizontal and vertical orientations. These new CSS features allow a mixture of horizontal and vertical text regions on the same page. The specification also adds support for such things as isolation in bidirectional text, glyph orientation controls, and short, inline horizontal runs in lines of vertical text.

Please, read our press release for additional information and acknowledgements.
