Angular 2 Dart: How to add body class from inside component?

css dart angular2-template angular-dart angular2-dart

There are two way.

You can use

@HostBinding('class.someclass') bool isSomeClass = true;

in the root component if it has

selector: 'body'

document.querySelector('body').classes.add('someClass');

You can use :host-context(...) to style a component depending on a selector matching a parent

:host-context(body.someClass) {  background-color: red;}

will make the background color red when the body element has class="someClass" set.
