Top of my app cut

Hello,

The top of my app is cut off and not showing.

Do you have any idea to solve the problem ?

folder.page.html :

<ion-header>
  <ion-toolbar>
    <ion-buttons slot="secondary">
      <ion-button>
        <ion-menu-button></ion-menu-button>
      </ion-button>
    </ion-buttons>
    <ion-buttons slot="primary">
      <ion-button color="danger">
        <ion-icon name="log-in-outline"></ion-icon>
      </ion-button>
    </ion-buttons>
    <ion-title>Bienvenue</ion-title>
  </ion-toolbar>
</ion-header>
<ion-content>
  <div id="container">
      <ion-refresher slot="fixed" pullFactor="0.5" pullMin="100" pullMax="200" (ionRefresh)="doRefresh($event)">
        <ion-refresher-content></ion-refresher-content>
      </ion-refresher>

try to add these ine in your page.scss file

ion-content{
margin-top:70px;
}

Nothing changes.

The only way I’ve found yet is this :

<ion-grid style="margin-top: 30vw;">
