The CSS Working Group has published a First Public Working Draft of CSS Overscroll Behavior Module Level 1. This module defines overscroll-behavior to control the behavior when the scroll position of a scroll container reaches the edge of the scrollport. This allows content authors to hint that the boundary default actions, such as scroll chaining and overscroll, should not be triggered.

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

The Web Authentication Working Group has published a First Public Working Draft of Web Authentication: An API for accessing Public Key Credentials Level 2. This specification defines an API enabling the creation and use of strong, attested, scoped, public key-based credentials by web applications, for the purpose of strongly authenticating users. Conceptually, one or more public key credentials, each scoped to a given WebAuthn Relying Party, are created by and bound to authenticators as requested by the web application. The user agent mediates access to authenticators and their public key credentials in order to preserve user privacy. Authenticators are responsible for ensuring that no operation is performed without user consent. Authenticators provide cryptographic proof of their properties to Relying Parties via attestation. This specification also describes the functional model for WebAuthn conformant authenticators, including their signature and attestation functionality.

Today W3C and the WHATWG signed an agreement to collaborate on the development of a single version of the HTML and DOM specifications. The Memorandum of Understanding jointly published as the WHATWG/W3C Joint Working Mode gives the specifics of this collaboration. This is the culmination of a careful exploration of effective partnership mechanisms since December 2017 after the WHATWG adopted many shared features as their work-mode and an IPR policy.

The HTML Working Group which we will soon recharter will assist the W3C community in raising issues and proposing solutions for the HTML and DOM specifications, and bring WHATWG Review Drafts to Recommendation.

Motivated by the belief that having two distinct HTML and DOM specifications claiming to be normative is generally harmful for the community, and the mutual desire to bring the work back together, W3C and WHATWG agree to the following terms:

• W3C and WHATWG work together on HTML and DOM, in the WHATWG repositories, to produce a Living Standard and Recommendation/Review Draft-snapshots
• WHATWG maintains the HTML and DOM Living Standards
• W3C facilitates community work directly in the WHATWG repositories (bridging communities, developing use cases, filing issues, writing tests, mediating issue resolution)
• W3C stops independent publishing of a designated list of specifications related to HTML and DOM and instead will work to take WHATWG Review Drafts to W3C Recommendations

W3C remains committed to ensuring that HTML development continues to take into account the needs of the global community, and continues to improve in areas such as accessibility, internationalization and privacy while providing greater interoperability, performance and security.
