Ionic 4滑块分页点与文本重叠

我有离子幻灯片组件显示一些幻灯片。每个幻灯片的内容根据服务动态呈现。

 <div style="padding:15px; padding-top:30px;background-color: #232536">
  <ion-slides pager="true">
    <ion-slide *ngFor="let gal of core.gallery">
      <div>
        <img *ngIf="gal.type=='image'" src="{{gal.link}}">
        <iframe *ngIf="gal.type == 'video'" style="width: 100%" [src]="getVideoUrl(gal.link)" frameborder="0" allow="accelerometer; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
        <ion-row>
          <ion-col text-left><h2 style="color:white" >My Title</h2>
          </ion-col>
        </ion-row>
        <ion-row>
          <ion-col style="color:#A2A0B2" text-left>{{gal.desc}}</ion-col>
        </ion-row>
      </div>
    </ion-slide>
  </ion-slides>
