The CSS Working Group has published CSS Fonts Module Level 3 as a W3C Recommendation. This CSS Module describes how to specify fonts used in CSS, including Web Fonts downloaded on demand. It also describes how to access advanced typographic features in fonts, and how to control font loading. This specification is implemented in all modern browsers.

The Audio Working Group invites implementations of Web Audio API Candidate Recommendation. Web Audio is a high-level Web API for processing and synthesizing audio in web applications. The primary paradigm is of an audio routing graph, where a number of AudioNode objects are connected together to define the overall audio rendering. The actual processing will primarily take place in the underlying implementation, but using AudioWorklet, direct script processing and synthesis from JavaScript or WebAssembly is also supported.

Today the World Wide Web Consortium released the Authorized Italian Translation of Web Content Accessibility Guidelines (WCAG) 2.1, Linee guida per l’accessibilità dei contenuti Web (WCAG) 2.1, contributed by International Web Association (IWA). This translation of WCAG 2.1 coincides with the adoption of the EU Web Accessibility Directive and the related European Standard EN 301 549, which refers to WCAG 2.1. You may read W3C Blog post to learn more about the Adoption of WCAG 2.1 in Europe. Roberto Scano from IWA, who coordinated the translation, published a blog post in Italian.

The Web Accessibility Initiative (WAI) encourages the development of W3C Authorized Translations of WCAG 2.1 in all languages. Read about the Policy for W3C Authorized Translations.

The CSS Working Group has published a Proposed Recommendation of Selectors Level 3. Selectors are patterns that match against elements in a tree, and as such form one of several technologies that can be used to select nodes in an XML document. Selectors have been optimized for use with HTML and XML, and are designed to be usable in performance-critical code. This document describes the selectors that already exist in CSS1 [CSS1] and CSS2 [CSS21], and further introduces new selectors for CSS3 and other languages that may need them.

Comments are welcome through 12 October 2018.

The W3C JSON-LD Working Group has published three First Public Working Drafts today.

• The JSON-LD 1.1 Syntax document defines a JSON-based format to serialize Linked Data. The syntax is designed to easily integrate into deployed systems that already use JSON, and provides a smooth upgrade path from JSON to JSON-LD. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Web services, and to store Linked Data in JSON-based storage engines. The 1.1 version of this specification will extend the existing JSON-LD 1.0 Recommendation, published in 2014.

• The JSON-LD 1.1 Processing Algorithms and API document defines a set of algorithms for programmatic transformations of JSON-LD documents. Restructuring data according to the defined transformations often dramatically simplifies its usage. Furthermore, this document proposes an Application Programming Interface (API) for developers implementing the specified algorithms. The 1.1 version of this specification will extend the existing JSON-LD Processing Algorithms and API Recommendation, published in 2014.

• The JSON-LD 1.1 Framing document defines an approach that allows developers to query by example and force a specific tree layout to a JSON-LD document.

All three documents are derived from Community Group Reports published by the JSON for Linking Data W3C Community Group.

The Working Group welcomes comments via the GitHub repository issues (see the respective documents’ headers for the reference of the repositories).

The CSS Working Group invites implementations of CSS Display Module Level 3 Candidate Recommendation. This module describes how the CSS formatting box tree is generated from the document element tree and defines the ‘display’ property that controls it.

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

The CSS Working Group invites implementations of two updated Candidate Recommendations of CSS Cascading and Inheritance Level 3 and CSS Cascading and Inheritance Level 4. The CSS module defined in these documents describes how to collate style rules and assign values to all properties on all elements. By way of cascading and inheritance, values are propagated for all properties on all elements. New in the Level 4 are the ‘revert’ keyword and <supports-condition> for the ‘@import’ rule.

The Devices and Sensors Working Group has published a First Public Working Draft of Geolocation Sensor. This specification defines the GeolocationSensor interface for obtaining geolocation of the hosting device.
