The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Writing Modes Level 3. CSS Writing Modes Level 3 defines CSS support for various international writing modes, such as left-to-right (e.g. Latin or Indic), right-to-left (e.g. Hebrew or Arabic), bidirectional (e.g. mixed Latin and Arabic) and vertical (e.g. Asian scripts). Inherently bottom-to-top scripts are not handled in this version.
