Update

I'm not sure if DOM is actually still supported in RC. The related statements aren't very clear. Something like

DOM is only for internal use. Either access the DOM directly or use a custom renderer.

I haven't see how a custom renderer might be implemented or how to provide an implementation depending on the current platform (webworker, server, DOM thread).

Update This seems to be the Angular2 way

import { DOM } from 'angular2/src/platform/dom/dom_adapter';

DOM.addClass(DOM.query("body"), 'fixed');

Import from .../src/... at your own risk. .../src/... is considered private implementation and you can't expect any guarantees that the API won't change without notice.

I tried it in Dart and it works fine (not sure if the TS import above is correct though). In Dart DOM is exported by package:angular2/angular2.dart

If you want to access a DOM element that's outside of your Angular application root, just use document.querySelector(), no need to involve Angular.
