You can style the component host in .css file using :host selector. I'd like to set the top on the component host from the component.
For example, given <app-test> </app-test>, I'd like to dynamically style host of AppTestComponent from the component itself.
Is this possible in Angular?
Yes, it is possible to dynamically style the component itself. First, you will need to inject ElementRef as a dependency. Then you can access the host via this._elementRef.nativeElement.
@Component({
//...
})
export class AppTestComponent {
constructor(private _elementRef: ElementRef) {
this._elementRef.nativeElement.style.color = 'red';
}
}
First of all, it's possibly a security risks according to Angular.
It is best to have an @Input class/style that let the parent passes into app-test. This way, the app-test doesn't have to worry about the environment around it, and does more than it needs to.
