The Web Applications Working Group has published a Working Draft of Gamepad. The Gamepad specification defines a low-level interface that represents gamepad devices. Currently, the only way for a gamepad to be used as input would be to emulate mouse or keyboard events, however this would lose information and require additional software outside of the user agent to accomplish emulation. The Gamepad API provides a solution to this problem by specifying interfaces that allow web applications to directly act on gamepad data. Learn more about the Rich Web Client Activity.

The Cascading Style Sheets (CSS) Working Group invites implementation of the Candidate Recommendation of CSS Syntax Module Level 3. This module describes, in general terms, the basic structure and syntax of CSS stylesheets. It defines, in detail, the syntax and parsing of CSS – how to turn a stream of bytes into a meaningful stylesheet. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Learn more about the Style Activity.

The Cascading Style Sheets (CSS) Working Group and the SVG Working Group invite implementation of the Candidate Recommendation of Compositing and Blending Level 1. Compositing describes how shapes of different elements are combined into a single image. There are various possible approaches for compositing. Previous versions of SVG and CSS used Simple Alpha Compositing. In this model, each element is rendered into its own buffer and is then merged with its backdrop using the Porter Duff source-over operator. This specification will define a new compositing model that expands upon the Simple Alpha Compositing model by offering: additional Porter Duff compositing operators; advanced blending modes which allow control of how colors mix in the areas where shapes overlap; compositing groups. In addition, this specification will define CSS properties for blending and group isolation and the properties of the ‘globalcompositeoperation’ attribute as defined in HTML Canvas 2D Context, Level 2.
