Having issues with directing focus towards a specific component in order to apply a

I am struggling to change the background of a custom component using mat-checkbox. I have tried various CSS solutions but none seem to work.

Here is my template code:

<form novalidate [formGroup]="form">
    <mat-form-field>
    <mat-label>{{labelText}}</mat-label>
    <mat-select class="select" #select [multiple]="multiselect" [formControl]="selectField" >
      <div class="select-all">
          <mat-checkbox *ngIf="multiselect" [(ngModel)]="allSelected"
                         class="mat-check-all"
                          [ngModelOptions]="{standalone: true}"
                          [indeterminate]="isIndeterminate()"
                          [checked]="isChecked()" 
                          (click)="$event.stopPropagation()"
                          (change)="toggleAllSelection($event)">{{text}}</mat-checkbox>
      </div>
      <mat-option *ngFor="let item of data" [value]="item[idField]">
        {{item[fieldName]}}
      </mat-option>
    </mat-select>
    </mat-form-field>
    </form>

I have attempted the following CSS styles without success:

.mat-checkbox-checked.mat-accent .mat-checkbox-background {
    background-color: rgb(49, 201, 11);
  }
.mat-check-all .mat-checkbox-checked.mat-accent .mat-checkbox-background {
    background-color: rgb(49, 201, 11);
  }
.select-all .mat-check-all .mat-checkbox-checked.mat-accent .mat-checkbox-background {
    background-color: rgb(49, 201, 11);
  }
.select .select-all .mat-check-all .mat-checkbox-checked.mat-accent .mat-checkbox-background {
    background-color: rgb(49, 201, 11);
  }
::ng-deep .select .select-all .mat-check-all .mat-checkbox-checked.mat-accent .mat-checkbox-background {
    background-color: rgb(49, 201, 11);
  }

None of the above CSS changes had any effect on the checkbox. When I used:

::ng-deep .mat-checkbox-checked.mat-accent .mat-checkbox-background {
    background-color: rgb(49, 201, 11);
  }

it affected all checkboxes in the form, not just the one in my component. How can I target only the checkbox within my custom component?

To enhance the styling of your form, consider adding a custom class to it or enclosing it within a div with the specified class and then utilize ::ng-deep in the following manner:

<form novalidate [formGroup]="form" class="my-custom-form">
    <mat-form-field>
    <mat-label>{{labelText}}</mat-label>
    <mat-select class="select" #select [multiple]="multiselect" [formControl]="selectField" >
      <div class="select-all">
          <mat-checkbox *ngIf="multiselect" [(ngModel)]="allSelected"
                         class="mat-check-all"
                          [ngModelOptions]="{standalone: true}"
                          [indeterminate]="isIndeterminate()"
                          [checked]="isChecked()" 
                          (click)="$event.stopPropagation()"
                          (change)="toggleAllSelection($event)">{{text}}</mat-checkbox>
      </div>
      <mat-option *ngFor="let item of data" [value]="item[idField]">
        {{item[fieldName]}}
      </mat-option>
    </mat-select>
    </mat-form-field>
    </form>

.my-custom-form ::ng-deep .mat-checkbox-checked.mat-accent .mat-checkbox-background {
    background-color: rgb(49, 201, 11);
  }

This approach confines the impact of ng-deep solely to this particular form.

    </mat-select>
    </mat-form-field>
    </form>

.my-custom-form ::ng-deep .mat-checkbox-checked.mat-accent .mat-checkbox-background {
    background-color: rgb(49, 201, 11);

ng-shadow was always unnecessary and is now deprecated. Angular's built-in view encapsulation automatically isolates CSS styles within components, preventing them from affecting other components such as mat-checkbox.

If you want to apply global CSS styles, it's recommended to create a global stylesheet like styles.css and use specific selectors. One approach is to prefix the CSS rules with the component name:

In global styles.css file

.my-component .custom-select .check-all .checkbox-checked.accent-bg .checkbox-bg {
    background-color: rgb(49, 201, 11);
}

You can add this new global style file to the styles array in angular.json or import it directly into styles.scss if using SCSS.

Alternatively,

To make all CSS in a component's stylesheet global, you can disable view encapsulation for that specific component:

In the component.ts file

@Component({
  ...
  encapsulation: ViewEncapsulation.None,
})
export class MyComponent {}

To change the background of a label, you can implement the following code:

.mat-checkbox-label{ background-color: rgb(49, 201, 11);}

For altering the background of the check mark, use this code:

.mat-checkbox-checked.mat-accent .mat-checkbox-background{ background-color: rgb(49, 201, 11);}

Remember to include these classes in your main style file specified in the "styles" key of angular.json file, which typically looks like this:

"styles": [
          "src/styles.scss"
        ],
