Use Renderer

See here:https://angular.io/api/core/Renderer

and here:https://angular.io/api/core/Renderer#setElementClass

import { Renderer } from '@angular/core';

constructor(private render:Renderer) { }

ChangeScreen(event:any) {
 this.renderer.setElementClass(event.target,"selected",true);
}

In html:

Global

Or Render2:

See here:https://angular.io/api/core/Renderer2

and here:https://angular.io/api/core/Renderer2#addClass

import { Renderer2 } from '@angular/core';

constructor(private render:Renderer2) { }

ChangeScreen(event:any) {
 this.renderer.addClass(event.target,"selected");
}

In html:

Global
