The CSS Working Group invites implementations of CSS Conditional Rules Module Level 4. This module contains the features of CSS for conditional processing of parts of style sheets, based on capabilities of the processor or the environment the style sheet is being applied in. It includes and extends the functionality of CSS Conditional 3 [css-conditional-3], adding the ability to query support for particular selectors [SELECTORS-4] through the new selector() notation for supports queries.

The Second Screen Working Group Patent Advisory Group (PAG), launched in August 2021 in response to disclosures related to a specification of the Second Screen Working Group, has issued an Update to the Call for Prior Art to seek prior art that is available in the public domain or on terms consistent with W3C’s Royalty-Free Licensing Requirements. The update contains questions about prior art related to digital audio, digital imaging, and multimedia networking technology from the mid-2000s.

Feedback should be directed to group-secondscreen-prior-art@w3.org by 31 March 2022. For more information about the Second Screen Working Group PAG, see its home page and charter.

The CSS Working Group invites implementations of CSS Color Adjustment Module Level 1. This module introduces a model and controls over automatic color adjustment by the user agent to handle user preferences, such as “Dark Mode”, contrast adjustment, or specific desired color schemes.

The Web Real-Time Communications Working Group published today Media Capture Depth Stream Extensions as a Discontinued Draft, due to lack of implementation momentum. The specification expected to extend the Media Capture and Streams specification to allow a depth stream to be requested from the web platform using APIs familiar to web authors.

Publication as a Discontinued Draft implies that this document is no longer intended to advance or to be maintained. It is inappropriate to cite this document as other than abandoned work.

The National Academy of Arts and Sciences has released its 2021 list of Technology & Engineering Emmy® Awards today and we were delighted to discover that the Web Fonts Working Group, along with MPEG, will be honored for standardizing font technology for custom downloadable fonts and typography for web and TV devices.

This award represents the culmination of a quarter-century of work at W3C. Web Fonts enable people to use fonts on demand over the web without requiring installation in the operating system. W3C has experience in downloadable fonts through HTML, CSS2, and SVG. Downloadable fonts were not common on the web due to the lack of an interoperable font format. The Web Fonts effort addresses that through the creation of an industry-supported, open font format for the web called “WOFF” (Web Open Font Format) whose version 2, which became a standard in 2018, is deployed in all major web browsers and powers a vast majority of sites.

This is the third Emmy® Award in Technical & Engineering W3C has won. We will be working with our colleagues to send delegates to the ceremony that will be part of the National Association of Broadcasters (NAB) show in Las Vegas on April 25, 2022.

The Technology & Engineering Emmy® Awards are awarded to a living individual, a company, or a scientific or technical organization for developments and/or standardization involved in engineering technologies that either represent so extensive an improvement on existing methods or are so innovative in nature that they materially have affected television.

The Web Fonts Working Group has published a First Public Working Draft of Incremental Font Transfer (IFT) via Range Request which focuses on incremental font transfer via HTTP range requests. IFT is a collection of technologies that help decrease the perceived latency between the time when a browser realizes it needs a font and when the necessary text can be rendered with that font. Without IFT, browsers need to download every last byte of a font before it can render any characters using that font. The specification describes the “Range-request method” in which the browser uses HTTP range requests to download only specific regions of the font file that it needs. This method has best performance on Chinese, Japanese, and Korean languages as these languages usually have the largest font files, and usually include many glyphs.
