Remove padding from mat-list-item

Question

The mat-list component in angular/material2 applies a top and bottom padding of 16px. I'd like to make this 0px. I've tried applying a style with a higher specificity but it isn't working (or I'm doing it wrong).The style I'm trying to override is:

I'm trying to override this with:

.list .mat-list .mat-list-item .mat-multi-line .mat-list-item-content {
  padding-top: 0;
  padding-bottom: 0;
}

<div class="list">
  <mat-list>
    <mat-list-item *ngFor="let item of queue">
      <h1 matLine>{{ item.id }}: {{ item.status}} {{ item.statusDate }}</h1>
      <p matLine>{{ item.name }}</p>
      <p matLine>for {{ item.customer }}</p>
      <div matLine>
        <button mat-icon-button (click)="openTab(item)">
          <mat-icon fontIcon="icon-open"></mat-icon>
        </button>
        <button *ngIf="showAssignToMe" mat-icon-button (click)="assignToMe(item)">
          <mat-icon fontIcon="icon-assign_to_me"></mat-icon>
        </button>
        <button mat-icon-button (click)="notes(item)">
          <mat-icon fontIcon="icon-comment"></mat-icon>
        </button>
      </div>
    </mat-list-item>
  </mat-list>
</div>

Answer 1

None of the previous proposions worked for me on Angular 6, 7 & 8

What I proposed is a deprecated solution (https://angular.io/guide/component-styles#deprecated-deep--and-ng-deep) but it still continues to work:

:host /deep/ .mat-list-item-content {
  padding: 0!important;
}
