ionic 3 angular ion-slide vertical align top

I am using ionic 3 ion-slides and ion-slide. The issue I am facing is the contents are in the center and I want it to be top aligned. Code looks like:

<ion-content padding>

    <ion-slides pager>
      <ion-slide style="vertical-align:top">
          <ion-card padding>
           <ion-card-header class="ha-card-header">About you</ion-card-header>
              <ion-card-content>
                    <ion-label>Family Size&nbsp;<ion-badge>{{energyProfile.familySize}}</ion-badge></ion-label>
                    <ion-item no-padding>
                        <ion-range [(ngModel)]="energyProfile.familySize" min="0" max="10" step="2">
                          <ion-icon range-left small name="person"></ion-icon>
                          <ion-icon range-right name="people"></ion-icon>
                        </ion-range>
                    </ion-item>
              </ion-card-content>
            </ion-card>
      </ion-slide>
</ion-slides>
<ion-content>
