Angular2: Component host property

I have added class to host tag.

Like following:

• Component

  @Component({
    selector: 'mytag',
    templateUrl: './layout.template.html',
    host: {
      'class' : 'myclass1 myclass2 myclass3'
    }
  })
  export class MyTagComponent {
  

• View code

  <mytag></mytag>

• Result

  <mytag class="myclass1 myclass2 myclass3"></mytag>
