Make ionic ion-item have a transparent background

Issue

Is there a way to make the background of an ionic 2 <ion-item> be transparent?

I have tried this CSS but it doesn't make the item transparent:

.list .item, .item-content .item-inner .item-block .item-ios
{
  background: transparent !important;
}

ADDED CODE

My HTML looks like this:

<ion-content class="pu-my-plans-background">

  <div *ngIf="hasPlans">
    <ion-list no-lines class="pu-item-list">
      <!--<ion-item-group reorder="true" (ionItemReorder)="reorderItems($event)">-->
        <ion-item-sliding *ngFor="let plan of plans; let i = index" >
          <ion-item class="pu-section-list-item pu-my-plans-item" (click)="editPlan(plan.id, plan.rev, plan.title, i)">
            {{ plan.title }}
            <br>
            <span class="pu-my-plans-plan-date">{{ plan.updated}}</span>
            <button *ngIf="plan.important" ion-button clear item-right>
              <ion-icon name="ios-alert-outline"></ion-icon>
            </button>
          </ion-item>
          <ion-item-options side="right">
            <button ion-button color="danger" (click)="deletePlan(plan.id, plan.rev)">
              <ion-icon name="delete"></ion-icon>
              Delete
            </button>
          </ion-item-options>
        </ion-item-sliding>
      <!--</ion-item-group>-->
    </ion-list>
  </div>

</ion-content>

And my CSS like this:

page-my-plans {

}

.pu-my-plans-plus-circle {
  display: block;
  //border: 2px solid white;
  background-color: $pu-orange;
  border-radius: 50%;
  height: 38px;
  width: 38px;
}

.pu-my-plans-plus-circle span {
  font-size: 38px;
  font-weight: 100;
  color: white;
  position: absolute;
  top: -7px;
  left: 8.5px;
}
.pu-plan-addButton {
  font-size: 30px;
  margin-right: 14px;
  margin-top:-2px;
}


.pu-section-list-item{
  color: white;
  background-color: black;
  font-weight:$pu-item-font-weight;
  font-size:$pu-item-font-size;
  padding-left:20px;
  padding-right:0px;
}
.item{
  background: transparent !important
}
// THEMING CSS
// ===========
//
.pu-my-plans-background {
  background-image: url("../assets/img/my_plan_bg@2x.png");
  background-size: cover !important;
}
.pu-my-plans-item {
  border-style:solid;
  border-bottom-width: 2px;
  border-bottom-color: $pu-orange;
}
.pu-my-plans-plan-date {
  color: $pu-orange;
  font-size: 11px;
  font-weight: 200;
}

I have tried every combination of styling the ionic 2 items as I can think of but the best I can get with this is to get a white background behind the ion-item. The ion-content has an image background but I can't get to see this through the ion-item.

Solution

For the ionic 2 item sliding background color you can change the main sass variable

 $item-ios-sliding-content-background(transprent);
 $item-md-sliding-content-background(transprent);

In your src -> theme -> variables.scss file

you can find all the variables here
