I want to remove `padding` from my ion-item so that it can occupy the full `width` of the page.

Please look in the dev tools to see the `padding` around the ion-item.

```html
<ion-content padding>
  <ion-list>
    <ion-item>
      <ion-thumbnail>
        <img class="imgmg" src="...">
      </ion-thumbnail> 
      <h2>Text</h2>
    </ion-item>
  </ion-list>
</ion-content>
```

The ion-item has a padding of 16px, when I inspect the ion-item and also on the class="scroll-content" there I found scss in the inspector with 

```
ion-app.md [padding] .scroll-content {
    padding: 16px;
}

```

If I remove this padding then ion-item can occupy the whole width by removing this padding, but When I use this in my scss file the padding is not removed.
