The Cascading Style Sheets (CSS) Working Group has published the First Public Working Draft of CSS Regions Module . The CSS Regions module allows content to flow across multiple areas called regions. The regions do not necessarily follow the document order. The CSS Regions module provides an advanced content flow mechanism, which can be combined with positioning schemes as defined by other CSS modules such as the Multi-Column Module or the Grid Layout Module to position the regions where content flows.

The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Writing Modes Module Level 3. CSS3 Writing Modes defines CSS features to 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).

The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Image Values and Replaced Content Module Level 3 . This CSS Image Values and Replaced Content module has two parts. First, it defines the syntax for image values in CSS. image values can be a single URI to an image, a list of URIs denoting a series of fallbacks, a reference to an element in the document, or gradients. Second, it defines properties used to control the interaction of replaced content and the CSS layout algorithms. These properties can affect the used image resolution for bitmaps, the replaced object's orientation, and whether and how to preserve the object's aspect ratio. Learn more about the Style Activity .

On 24 November 2010 the XHTML2 Working Group published three revised Recommendations: XHTML 1.1 - Module-based XHTML Second Edition , XHTML Basic 1.1 Second Edition , and XHTML-Print Second Edition . A related specification, XHTML Modularization, defines a framework for building XHTML language definitions from a set of modules. Each of the revised Recommendations combines modules to different ends. XHTML 1.1 is a "full" set of modules, XHTML Basic 1.1 is a minimal set of modules for environments such as mobile phones, PDAs, pagers, and set top boxes. XHTML Print targets printing, e.g., from mobile devices to printers that may not be full-featured. These revisions incorporate corrections to errata; see each document for the list of changes.

19 November 2010 The Web Applications Working Group has published the First Public Working Draft of HTML5 Web Messaging . This specification defines two mechanisms for communicating between browsing contexts in HTML documents. Cross document messaging allows documents to communicate with each other regardless of their source domain, in a way designed to not enable cross-site scripting attacks. Channel messaging allows independent pieces of code (e.g. running in different browsing contexts) to communicate directly. Learn more about the Rich Web Client Activity .

26 October 2010 The Web Performance Working Group has published the First Public Working Draft of Navigation Timing . To address the need for complete information on user experience, this document introduces the NavigationTiming interfaces. This interface allows JavaScript mechanisms to provide complete client-side latency measurements within applications. With the proposed interface, the previous example can be modified to measure a user's perceived page load time. Learn more about the Rich Web Client Activity .
