All styles (except the main global stylesheet) in Angular 2/4 are encapsulated, so when you're including stylesheets like this:

@Component({
  selector: 'component-name',
  templateUrl: './component.html',
  styleUrls: ['./component.css']
})

All styles from component.css will be applied ONLY to component.html (if you doesn't use things like /deep/ and the same). So feel free to change the width of current layout, it will not affect other layouts!
