@Directive({
  selector: '[appAutoFullHeight]'
})
export class AutoFullHeightDirective implements AfterViewInit {
  constructor(
    private el: ElementRef,
    private renderer: Renderer2
  ) {
    const windowHeight = window.innerHeight > 600 ? window.innerHeight : 600;
    const calculatedheight = `${windowHeight - 150}px`; // can be simply windowheight but you can do the adjuscement here
    this.renderer.setStyle(this.el.nativeElement, 'height', calculatedheight);

  ngAfterViewInit() {
