In July 2012, WHATWG and W3C decided on a degree of separation. W3C will continue the HTML5 specification work, focusing on a single definitive standard, which is considered a "snapshot" by WHATWG. The WHATWG organization continues its work with HTML5 as a "living standard". The concept of a living

For a number of years, both groups then worked together. In 2011, however, the groups came to the conclusion that they had different goals: the W3C wanted to publish a "finished" version of "HTML5", while the WHATWG wanted to continue working on a Living

Before the ceding of authority, W3C and WHATWG had been characterized as both working together on the development of HTML5, and yet also at cross purposes ever since the July 2012 split. The W3C "HTML5" standard was snapshot-based (HTML5, HTML 5.1, etc.) and static, while the WHATWG "HTML living
