Elemental a GWT abstraction layer that exposes the raw browser api's defined in the browser IDLs. So, Elemental is a 'to the metal' way of programming the browser using GWT Java.

GWT Reference Guide - https://developers.google.com/web-toolkit/articles/elemental

Elemental includes every HTML5 feature, including DOM access of course, but also bleeding edge features like WebGL, WebAudio, WebSockets, WebRTC, Web Intents, Shadow DOM, the File API, and more. We can do this because we generate Java code directly from the WebIDL files used by JavaScript engines.

Elemental also includes high-performance collections and a new JSON library. These libraries work equally well in a browser or in a server (JVM) environment.
