HTML 5
HTML5 version was released in October 28, 2014 after a long time. It was released as a stable w3C recommendation. The Document Type Declaration <!DOCTYPE html> is not included then different browser will revert to “quirks mode” for rendering. HTML5 motive was to keep the language completely readable by humans and completely understood by the computer and browser. so many elements and multimedia are added and can be accessed easily offline as well. It is still in development mode that’s why no browser has full HTML5 support.
