HTML5 is the latest version of the de facto web programming markup language HTML. HTML and HTML5 standards are created and published by “World Wide Web Consortium” or W3C. HTML5 is created by the Web Hypertext Application Technology Working Group or WHATWG group in the W3C. The WHATWG group consists of companies like Apple, Google, Mozilla, and Microsoft.

HTML5历史 (HTML5 History)

Even the usage of the HTML5 is about 6 years the work started a long time ago. The WHATWG working group began work in 2004. The HTML 4.01 had not been updated since 2000. The first public working draft of the HTML5 specification is produced on 22 January 2008 by Google and Apple.

甚至HTML5的使用也已经是很久以前开始的6年了。 WHATWG工作组于2004年开始工作。HTML4.01自2000年以来未进行过更新。HTML5规范的第一个公共工作草案由Google和Apple于2008年1月22日发布。

HTML5 was initially released in October 2014 as a recommended standard by W3C. HTML5 is created as a living standard which means it will regularly be updated without waiting for a long time. HTML5.1 is released in 2016 with some minor updates and the most recent HTML5 version 5.2 is released in 2017. Even HTML5.3 draft is created in 2017 it is not complete and not recommended by the W3C.

HTML5最初于2014年10月发布，是W3C推荐的标准。 HTML5被创建为一种生活标准，这意味着它将定期更新，而无需等待很长时间。 HTML5.1于2016年发布，并进行了一些小的更新，最新HTML5版本5.2于2017年发布。即使HTML5.3草案是在2017年创建的，它也不完整，W3C也不建议这样做。
