Show cards side by side

I have cards that I want to show 2 by 2 per line

  <ion-card class="cardo" *ngFor="let transient of transients" (click)="itemTapped($event, transient)">

.cardo {
  width: 40%;

How do I make it so that they appear side by side?

Sorry the problem is solved. I’m bad with css. I just put

  display: inline-block;
