Having trouble with CSS values not being applied to dynamically injected HTML div elements in Angular 4?

Link to Codepen

My Angular calendar application runs smoothly without any errors. However, I am encountering an issue where the CSS styles are not being applied to the page.

When I implemented this separately, everything worked fine. But as soon as I included it in my Angular project, the CSS stopped working. The problem lies in referencing the 'div' that contains the content.

Below is the code snippet:

holidays.ts

@Component({
  templateUrl: './holidays.component.html',
  styleUrls: ['./../../../webroot/css/pages/holidays/only_holidays.min.css'],
  styles: [`

  `],
})
export class HolidaysPageComponent extends AppComponent {

  ngOnInit(){
    this.testFunction();
  }

  // More functional code here...

}

Contents of only_holidays.css:

body{
  background-color: #F5F1E9;
}
#calendar{
  margin-left: auto;
  margin-right: auto;
  width: 520px;
  font-family: 'Lato', sans-serif;
}

// CSS styles continue...

The issue seems to be with the way the styles refer to the 'div.' For more details and to access the full code visit: Codepen Link

Answer №1

It seems like the issue here is related to css encapsulation in Angular. By default, Angular uses the Emulated encapsulation method, which adds an attribute to all DOM elements within a component and applies it to the corresponding CSS rules. However, when injecting HTML dynamically without using Angular's methods, this attribute may not be included. In such cases, you can switch to the None option to prevent Angular from adding the attribute to your CSS.

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

@Component({
  templateUrl: './holidays.component.html',
  styleUrls:['./../../../webroot/css/pages/holidays/only_holidays.min.css'],
  encapsulation: ViewEncapsulation.None
})

Keep in mind that by using the None option, your CSS styles won't be encapsulated only for this specific component but will be accessible throughout your application.

For more information on ViewEncapsulation, you can refer to the official documentation: https://angular.io/api/core/ViewEncapsulation
