2012年12月17日W3C(World Wide Web Consortium)宣布HTML5和Canvas 2D技术规范定稿。尽管W3C的正式标准尚未发布,但这份技术规范意味着HTML5的功能特性已经完成定义,对于企业和开发者而言有了一个可以参照实现和规划的目标。


W3C CEO Jeff Jffe说:“Web技术应用得范围越广泛,就意味越需要一个稳定的技术标准。时至今日,企业们知道未来可以依靠HTML5做些什么以及他们的客户会要求什么。同样,开发者也知道如何将HTML5技术应用于智能手机、汽车、电视、电子书、数字签名以及一些未知的设备上。”

为了减小浏览器的”分裂”(fragmentation)W3C开始着手W3C标准化致力于互操作性和测试。W3C计划在2014年冻结HTML5技术规范。以此同时,W3C社区将继续开展下一代HTML功能特性的定义,包括对HTML5 accessibility(无障碍)、响应式图片、自适应流等特性的支持。

HTML工作组也发布了HTML5.1和Cavans 2D Level2第一版草案。了解更多请访问http://www.w3.org/html/。

HTML5 Definition Complete, W3C Moves to Interoperability Testing and Performance

17 December 2012


W3C published today the complete definition of the HTML5 and Canvas 2D specifications. Though not yet W3C standards, these specifications are now feature complete, meaning businesses and developers have a stable target for implementation and planning. “As of today, businesses know what they can rely on for HTML5 in the coming years, and what their customers will demand,” said Jeff Jaffe, W3C CEO. HTML5 is the cornerstone of the Open Web Platform, a full programming environment for cross-platform applications with access to device capabilities; video and animations; graphics; style, typography, and other tools for digital publishing; extensive network capabilities; and more.

To reduce browser fragmentation and extend implementations to the full range of tools that consume and produce HTML, W3C now embarks on the stage of W3C standardization devoted to interoperability and testing. W3C is on schedule to finalize the HTML5 standard in 2014. In parallel, the W3C community will continue its work on next generation HTML features, including extensions to complement built-in HTML5 accessibility, responsive images, and adaptive streaming.

The HTML Working Group also published first drafts of HTML 5.1, HTML Canvas 2D Context, Level 2, and main element, providing an early view of the next round of standardization. Learn more About HTML.
