Angular 5 - add style to specific element dynamically
I'm super late to this party, but NO! DO NOT USE DOCUMENT.QUERYSELECTOR. That is NOT how you style an Angular DOM element!
<div [ngStyle]="{'top.px': divStyle}">
Then in your component, you have
ngAfterViewInit() { this.divStyle = 200; }
As per our comments, You should be using document.querySelector
after a life cycle hook
ngAfterViewInit() { (document.querySelector('.app-alerts') as HTMLElement).style.top = '150px';}
I came across a page that has good explanation and sample code to add the style dynamically in Angular 2+.Attach the style dynamically in Angular
