The Accessible Platform Architectures Working Group has published a First Public Working Draft of XR Accessibility User Requirements. This document lists user needs and requirements for people with disabilities when using virtual reality or immersive environments, augmented or mixed reality and other related technologies (XR). This document is most explicitly not a collection of baseline requirements. It is also important to note that some of the requirements may be implemented at a system or platform level, and some may be authoring requirements.

The CSS Working Group has published two First Public Working Drafts today:

• Resize Observer: This specification describes an API for observing changes to Element’s size.
• CSS Scroll Anchoring Module Level 1: Changes in DOM elements above the visible region of a scrolling box can result in the page moving while the user is in the middle of consuming the content. This spec proposes a mechanism to mitigate this jarring user experience by keeping track of the position of an anchor node and adjusting the scroll offset accordingly.

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