The CSS Working Group invites implementations of an updated Candidate Recommendation of CSS Images Module Level 3. This module contains the features of CSS level 3 relating to the <image> type and some replaced elements. It includes and extends the functionality of CSS level 2 [CSS2]. The main extensions compared to CSS2.1 are the generalization of the <url> type to the <image> type, several additions to the <image> type, a generic sizing algorithm for images and other replaced content in CSS, definitions for interpolating several <image> types, and several properties controlling the interaction of replaced elements and CSS’s layout models.
