The Web Notification Working Group has published a Proposed Recommendation of Web Notifications. Web Notifications defines an API for end-user notifications. A notification allows alerting the user outside the context of a web page of an occurrence, such as the delivery of email. Comments are welcome through 08 October.

The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Cascading and Inheritance Level 4. This CSS module 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. One of the fundamental design principles of CSS is cascading, which allows several style sheets to influence the presentation of a document. When different declarations try to set a value for the same element/property combination, the conflicts must somehow be resolved.

The Device APIs Working Group and the Web Real-Time Communications Working Group have published a Working Draft of MediaStream Recording. This document defines a recording API for use with MediaStreams as defined in GETUSERMEDIA. This API attempts to make basic recording very simple, while still allowing for more complex use cases.

The Multimodal Interaction Working Group has published a Working Draft of EMMA: Extensible MultiModal Annotation markup language Version 2.0. This specification describes markup for representing interpretations of user input (speech, keystrokes, pen input, etc.) and productions of system output together with annotations for confidence scores, timestamps, medium, etc. It forms part of the proposals for the W3C Multimodal Interaction Framework.

The Device APIs Working Group has published two Working Drafts today:

Ambient Light Events: The DeviceLightEvent interface provides information about the ambient light levels, as detected by the device’s light detector, in terms of lux units. This specification defines a means to receive events that correspond to a light sensor detecting the presence of a light.

Proximity Events: The DeviceProximityEvent interface provides web developers information about the distance between the hosting device and a nearby object. This specification defines a means to receive events that correspond to a proximity sensor detecting the presence of a physical object.

After a successful first run of the course that drove over 77K enrollees, W3Cx re-opens registration for the HTML5 Part-1 MOOC course, to start on 5 October 2015. The course lasts 6 weeks, and is taught by Michel Buffa, Professor at the University of Côte d’Azur.

This HTML5 Part 1 course focuses on Web design fundamentals at an intermediate level, and allows Web developers and designers to test their new skills through numerous interactive exercises and practical assignments. Read the course reviews, its description and register! Learn lots and have fun!
