The CSS Working Group has published a Candidate Recommendation of CSS Grid Layout Module Level 2 and an updated Candidate Recommendation of CSS Grid Layout Module Level 1. This CSS module defines a two-dimensional grid-based layout system, optimized for user interface design. In the grid layout model, the children of a grid container can be positioned into arbitrary slots in a predefined flexible or fixed-size layout grid. Level 2 expands Grid by adding “subgrid” capabilities for nested grids to participate in the sizing of their parent grids. Comments are welcome by 18 October 2020.

The Timed Text Working Group has published TTML Profiles for Internet Media Subtitles and Captions 1.2 as a W3C Recommendation. IMSC 1.2 is the latest version of the IMSC standard, which defines profiles of the Timed Text Markup Language for worldwide subtitling and captioning interchange. IMSC is used in applications such as CMAF, DASH, IMF, ATSC, DVB, etc. and is designed to work with SMPTE-TT, EBU-TT-D and other regional practices. IMSC 1.2 adds support for downloadable font resources. This feature is intended to improve fidelity by providing clients the exact font used during authoring and allow images to be added to inline text content – while providing graceful fallback. IMSC 1.2 is otherwise primarily a maintenance release that fixes outstanding bugs and generally improves specification text.

The Web Applications Working Group has published a First Public Working Group Note of Web App Manifest – Application Information. This document is a registry of supplementary members for the Web App Manifest specification that provide additional metadata to an application manifest. This metadata can be used in a digital storefront or other surfaces where this web application may be marketed or distributed, or to enhance an installation dialog when installing a web application.

The CSS Working Group invites implementation of an updated Candidate Recommendation of Media Queries Level 4. Media Queries allow authors to test and query values or features of the user agent or display device, independent of the document being rendered. They are used in the CSS @media rule to conditionally apply styles to a document, and in various other contexts and languages, such as HTML and JavaScript. Media Queries Level 4 describes the mechanism and syntax of media queries, media types, and media features. It extends and supersedes the features defined in Media Queries Level 3.

W3C today adopted a new Code of Ethics and Professional Conduct (CEPC), developed by the Positive Work Environment Community Group. W3C’s Code of Ethics and Professional Conduct defines accepted and acceptable behaviors and promotes high standards of professional practice. The goals of this code are to:

• Define acceptable and expected standards of behavior.
• Provide a benchmark.
• Ensure transparency in community and group management.
• Ensure an environment where people can participate without fear of harassment.
• Contribute to the identity of the organization.

This document supersedes the 2015 CEPC. Education and training materials are available from the Positive Work Environment public homepage.
