HTML5.1: The New Standard is Nearing Completion
HTML5 becoming the official standard in 2014 was a milestone for modern web development. Better semantics, and easier controls, especially on mobile devices, were central ideas of HTML5. About two years later, its successor, HTML5.1, is nearing completion. Many of the things that are new in HTML5.1 are already being used, and supported by most browsers.

“month” and “week” as New Input Forms
There are news in terms of forms as well. While HTML5 introduced new types for the “” element, like “email”, “url”, and “date”, for entering email and internet addresses, as well as dates, for example, there are two new entry types.
New Types for Form Entries: “month” and “week”

HTML5.1 didn’t only add new elements and attributes. It is also possible that some elements will be removed in the future. For instance, the elements “”, “
