Update to the Candidate Recommendation: CSS Writing Modes Level 3; First Public Working Draft: CSS Writing Modes Level 4

7 December 2017

The CSS Working Group invites implementations of an updated Candidate Recommendation of CSS Writing Modes Level 3. This document 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).

Along with this updated Candidate Recommendation, the group also published a First Public Working Draft of CSS Writing Modes Level 4. The difference from the CSS Writing Modes Level 3 is the set of features that were deferred from Level 3 due to later implementation uptake.

CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.
