Ion-item-group padding

Going through @smichelotti’s Ionic2 course on PluralSight… using this snippet:

<ion-content padding>
  <ion-list>
    <ion-item-group *ngFor="let division of teams">
      <ion-item-divider color="secondary">{{division.divisionName}}</ion-item-divider>
      <button *ngFor="let team of division.divisionTeams" ion-item (click)="itemTapped($event, team)">
        {{team.name}}
      </button>
    </ion-item-group>
  </ion-list>
</ion-content>

In the video, this renders as (secondary coloration extends to screen edges):

But in my browser it renders as (seconday coloration restricted by ion-item-group width):

What’s the trick to get the secondary coloration of the ion-item-divider to extend to the edges of the screen?

Sorted it out for myself. Just had to remove the padding attribute from the ion-content element.
