    import { renderCustomElement } from 'ngx-elements'
    
    @Component({
      selector: "hello-world",
      template: `
        <h1>Hello {{ name }}</h1>
        <input 
          [value]="name" 
          (input)="updateName($event.target.value)" 
         />
      `,

        h1 { 
         color: var(--h1-color, blue) 
        }
      `],
      encapsulation: ViewEncapsulation.ShadowDom
    })
    export class HelloWorldComponent {
