Separating Angular Material cards vertically

Question

I want to list items in an array vertically with cards, but there is no space between them. I tried to use padding but it seems it doesn't work.

card image

How can I have these cards spaced?

<ng-container *ngIf="titles?.length; else noTitle">
    <mat-card class="asd cardPardding" *ngFor="let title of titles">
      <p>
      {{title}}
      </p>
    </mat-card>
  </ng-container>

  <ng-template #noTitle>
    <mat-card class="asd cardPardding">
      <p>
      No title !
      </p>
  </mat-card>
  </ng-template>

This is css

.asd {
  width: 80%;
  margin: 0 auto; /* Added */
}

.inputasd {
  width: 100%;
}

.cardPadding {
  padding: 100px;
  margin-bottom: 50px;
}
