But still, my ion-content overlaps with ion-header

I am trying this usage example with ion-virtual-scroll . I tried fullscreen , padding , has_header and other solutions on the forum including old ionic versions.

I have the following code in my app.component.html .

<ion-app>
    <ion-header [translucent]="true">
      <ion-toolbar>
        <ion-title size="medium">
          <ion-img [src]="header_logo" height="150" width='150'></ion-img>
        </ion-title>
      </ion-toolbar>
    </ion-header>

  <ion-router-outlet></ion-router-outlet>
<ion-app>

and the ion-content is present in every component.

Answer 1

I posted the same question on ionic-forum , and Mike Hartington from ionic-team replied with the following.

Hey there. So this isn't actually how you should be structuring your DOM.

ion-header is not meant to be a “global” component in this case. It should be included in all your pages. This is probably why you're having issues.

So basically, I had to move ion-header from app.component.html to every page I will be building.
