What is the method for modifying the parent reusable component's style from its child component?

I'm facing an issue with a reusable component in my current project. I need to modify the style of this reusable component, but I can't seem to figure out how to override the parent component's style within my child component.

Parent reusable component:(settings-panel.component.html)

<button>
    <app-svg-icon [iconSrc]="iconSrc"></app-svg-icon>
</button>
<div [ngClass]="position" class="settings-panel" [hidden]="!panelIsVisible">
    <span class="arrow"></span>
    <ng-content></ng-content>
</div>

This is my current component(outage.component.html)

 <app-settings-panel class="outage-main" iconPath="alert.svg" position="right bottom">
     <div class="outage-panel">
        <div class="outage-heading">
            <span>Notifications</span>
            <span>New</span>
        </div>      
        <span *ngFor="let outage of outageArray">
            <button type="button" class="outage-group-item">
                <span>{{outage}}</span>
            </button>
        </span>
     </div>
 </app-settings-panel>

This is my current component (outage.component.scss)

.outage-main{
    div:nth-child(1) {
            border: 5px solid red !important; 
    }
}

I've been trying to update the parent component's div style, but it seems to only affect the current component's div. How can I make changes to the style in my settings-panel.component.html?

Answer №1

After consulting @vega's insight, I took a look at :host which ultimately resolved the issue I was facing.

:host ::ng-deep app-settings-panel {

    div.settings-panel {
        border: 5px solid red !important;
    }
}
