Introduction To HTML5 HTML Programming Tutorial in Hindi Urdu

The W3C proposed a greater reliance on modularity as a key part of the plan to make faster progress, meaning identifying specific features, either proposed or already existing in the spec, and advancing them as separate specifications. Some technologies that were originally defined in HTML5 itself are now defined in separate specifications:

HTML Working Group – HTML Canvas 2D Context;
Web Apps Working Group – Web Messaging, Web Workers, Web Storage, WebSocket, Server-sent events, Web Components
this was not part of HTML5 though); Note that the Web Applications Working Group was closed in October 2015 and its deliverables transferred to the Web Platform Working Group (WPWG).
IETF HyBi Working Group – WebSocket Protocol;
WebRTC Working Group – WebRTC;
Web Media Text Tracks Community Group – WebVTT.
