I am trying to use multiple CSS files in home.componenet.ts but
I am getting errors every time. Please assist me to fix this issue.
i tried to use two approaches but with both approaches , i am getting errors.
In first approach, I am using multiple CSS files in styleUrls and in second approach, i am using multiple CSS files in app.component.css by
importing multiple CSS files. In first approach, CSS plugin folder is under ClientApp->
app -> assets and in second approach, CSS plugin folder is under wwwroot
-> dist -> assets
First approach :
following is my code
import { Component } from '@angular/core';
import * as $ from 'jquery';
@Component({
selector: 'home',
templateUrl: './home.component.html',
styleUrls: ['~/app/assets/css/style.css','~/app/assets/css/colors/green.css']
})
export class HomeComponent {
public name = 'gfggfg';
}
