  <ion-card *ngFor="let details of checkOutAddr" round inset class="ion-card">
    <ion-item>
      <ion-row>

        {{details.stage}}
      </ion-row>

      <ion-row>
        {{details.main}}
      </ion-row>

      <ion-row>
        {{details.state}}
      </ion-row>

      <ion-row>
        <ion-col>
          <ion-icon ios="ios-call" md="md-call" item-left></ion-icon>
            {{details.phone}} 
        </ion-col>
      </ion-row>

      <ion-row>
        <ion-col>
          <ion-icon ios="ios-mail" md="md-mail" item-left></ion-icon> 
            {{details.mail}}
        </ion-col>
      </ion-row>
    </ion-item>
  </ion-card

I used the scss code as below:

.ion-card {
        background-color: slategray !important;
    }

How do i get the look and feel as below img:

In order to do it in a more Ionic2 way you need to replace the value of these sass variables:

$card-ios-background-color
$card-md-background-color
$card-wp-background-color

So, you just need to add the new value in app/theme/app.variables.scss, like this:

$card-ios-background-color: slategray;
$card-md-background-color: slategray;
$card-wp-background-color: slategray;
