Adjusting the transparency of TabBadge in Ionic 2

I am currently working on a project that involves tabs, and I'm looking to update the style of the badge when the value is 0. Unfortunately, I am unsure how to dynamically change the style of my tabs or adjust the opacity of the badge in the style.

My desired outcome looks like this:

Any help would be greatly appreciated! :)

Below is the code snippet I am using: 

<ion-tabs color="secondary"  (ionChange)="changeTabs()">
  <ion-tab [root]="tab1" tabTitle="tab1" tabBadge="{{this.session.getToDoCount()}}" tabBadgeStyle="notif"></ion-tab>
  <ion-tab [root]="tab2" tabTitle="tab2" tabBadge="{{this.session.getToComeCount()}}" tabBadgeStyle="notif"></ion-tab>
  <ion-tab [root]="tab3" tabTitle="tab3"></ion-tab>
</ion-tabs>

Answer №1

If the badge value is zero, you can use the ngClass directive to apply a custom style.

HTML:

<ion-item class="notifications">
  <ion-icon name="logo-twitter" item-left></ion-icon>
  Messages
  <ion-badge class="notification" item-right [ngClass]="{'zero': badgeValue === 0}">25</ion-badge>
</ion-item>

styles:

.notifications {
  .notification {
     background: #4caf50;
     color: #fff;
  }
  .notification.zero {
    background: #ccc;
  }
}
