HTML 5, Differences from HTML 4 Drafts Published

2009-04-23: The HTML Working Group has published a Working Draft of HTML 5. HTML 5 adds to the language of the Web: features to help Web application authors, new elements based on research into prevailing authoring practices, and clear conformance criteria for user agents in an effort to improve interoperability. This particular draft specifies how authors can embed SVG in non-XML text/html content, and how browsers and other UAs should handle such embedded SVG content. See also the news about moving some parts of HTML 5 to individual drafts. The full list of changes since the previous draft are listed in the updated companion document HTML 5 differences from HTML 4. Learn more about the HTML Activity.

W3C Invites Implementations of Media Queries

2009-04-23: The Cascading Style Sheets (CSS) Working Group invites implementation of the Candidate Recommendation of Media Queries. HTML4 and CSS2 currently support media-dependent style sheets tailored for different media types. For example, a document may use sans-serif fonts when displayed on a screen and serif fonts when printed. .screen. and .print. are two media types that have been defined. Media Queries extend the functionality of media types by allowing presentations to be tailored more precisely to device characteristics. Learn more about the Style Activity.

CSS 2.1 Candidate Recommendation Updated

2009-04-23: The Cascading Style Sheets (CSS) Working Group updated the Candidate Recommendation of Cascading Style Sheets Level 2 Revision 1 (CSS 2.1) Specification. CSS 2.1 is a style sheet language that allows authors and users to attach style (e.g., fonts and spacing) to structured documents (e.g., HTML documents and XML applications). CSS 2.1 corrects a few errors in CSS2 (the most important being a new definition of the height/width of absolutely positioned elements, more influence for HTML's "style" attribute and a new calculation of the 'clip' property), and adds a few highly requested features which have already been widely implemented. But most of all CSS 2.1 represents a "snapshot" of CSS usage: it consists of all CSS features that are implemented interoperably. This draft incorporates errata resulting from implementation experience since the previous publication. Learn more about the Style Activity.
