ng-deep is causing changes in sibling components

Facing a challenge with Angular Material Design as I discovered the need to utilize ng-deep to customize the styling of an accordion. The issue is that when I use this method, it affects another accordion in a different section which is undesirable.

Is this behavior intentional? How can I resolve this conflicting styling issue?

Answer №1

ng-deep has become outdated and is no longer supported by major browsers. For more information, check out the Angular Docs.

To address this issue, I recommend removing the view encapsulation from the component instead (None removes style encapsulation for that component, allowing you to target Angular Material styles).

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

@Component({
    selector: 'app-example-component',
    templateUrl: './example.component.html',
    styleUrls: ['./example.component.scss'],
    encapsulation: ViewEncapsulation.None
})

Answer №2

After some experimentation, I discovered a way to confine the styles within the component by enclosing the ::ng-deep code with :host as shown below:

:host {
    ::ng-deep {
        /* ... insert your custom styles here */
    }
}
