W3C Invites Implementations of CSS Scroll Snap Module Level 1 and CSS Values and Units Module Level 3; Level 4 is a First Public Working Draft

August 14th, 2018

The CSS Working Group invites implementations of two updated Candidate Recommendations of CSS Scroll Snap Module Level 1 and CSS Values and Units Module Level 3, and has just published CSS Values and Units Module Level 4 as a First Public Working Draft.

The CSS Scroll Snap Module contains features to control panning and scrolling behavior with “snap positions”. The CSS module, defined in the CSS Values and Units Module Level 3 and Level 4, describes the common values and units that CSS properties accept and the syntax used for describing them in CSS property definitions. See changes in Level 3 and Level 4.

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