The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Lists and Counters Module Level 3. This draft contains the features of CSS level 3 relating to list styling. It includes and extends the functionality of CSS level 2 [CSS21]. The main extensions compared to level 2 are a pseudo-element representing the list marker, and a method for authors to define their own list-styles.

The group also updated in place the 29 September 2011 Recommendation of CSS Namespaces Module Level 3. The changes include the addition of three grammar rules which aren’t used in the spec itself, to avoid having to add them to new specs that do need them; addition of an extra explanation to an example (“because…”); change to the term “rule sets” to “style rules.” Both are correct, but the latter is easier to understand.

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

The Cascading Style Sheets (CSS) Working Group invites implementation of two Candidate Recommendations:

• CSS Writing Modes Level 3. CSS Writing Modes Level 3 defines CSS support for various international writing modes, such as left-to-right (e.g. Latin or Indic), right-to-left (e.g. Hebrew or Arabic), bidirectional (e.g. mixed Latin and Arabic) and vertical (e.g. Asian scripts).
• CSS Shapes Module Level 1. CSS Shapes describe geometric shapes for use in CSS. For Level 1, CSS Shapes can be applied to floats. A circle shape on a float will cause inline content to wrap around the circle shape instead of the float’s bounding box.

The Web Application Security Working Group has published a Last Call Working Draft of User Interface Security Directives for Content Security Policy. This document defines directives for the Content Security Policy mechanism to declare a set of input protections for a web resource’s user interface, defines a non-normative set of heuristics for Web user agents to implement these input protections, and a reporting mechanism for when they are triggered. Comments are welcome through 18 June. Learn more about the Security Activity.

The Web Application Security Working Group has published a First Public Working Draft of Subresource Integrity. This specification defines a mechanism by which user agents may verify that a fetched resource has been delivered without unexpected manipulation. Learn more about the Security Activity.

W3C announced today a Workshop on the Web of Things, 25-26 June 2014, in Berlin (Germany). The event is hosted by Siemens.

The Web of Things is expected to have broad and sweeping economic and societal impact. Open standards will be critical to enabling exponential growth of the kind we experienced with the early days of the Web.

This workshop will examine the potential for open standards as a basis for services, either between devices, at the network edge, e.g. in home hubs, or in the cloud. It will discuss the use of web protocols and scripting languages for implementing services, the need for APIs for implementing drivers for specific IoT technologies, a shared approach to describing services as a basis for interoperability, and the underlying use of HTTP/COAP, Web Sockets, and EXI/JSON for RESTful services.

W3C membership is not required to participate. The event is open to all. All participants are required to submit an expression of interest or a longer position paper by 25 April 2014.

The Media Annotations Working Group published a Recommendation of Metadata API for Media Resources 1.0. This document defines an API to access metadata information related to media resources on the Web. The overall purpose is to provide developers with a convenient access to metadata information stored in different metadata formats. The API provides means to access the set of metadata properties defined in the Ontology for Media Resources 1.0 specification. Learn more about the Video on the Web Activity.
