The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Image Values and Replaced Content Module Level 3. This CSS Image Values and Replaced Content module has two parts. First, it defines the syntax for
image
values in CSS. image
values can be a single URI to an image, a list of URIs denoting a series of fallbacks, a reference to an element in the document, or gradients. Second, it defines properties used to control the interaction of replaced content and the CSS layout algorithms. These properties can affect the used image resolution for bitmaps, the replaced object's orientation, and whether and how to preserve the object's aspect ratio. Learn more about the Style Activity.
