title: Ionic 2: Remove background from custom component button in navbar
body: <p><strong>Q) How do I fix the styling on the custom component below so it looks like the plus sign, with inherited styling from the <code>&lt;ion-buttons&gt;</code> directive?</strong></p>
  
  <p>I'm using a custom component in my navbar: <code>&lt;notifications-bell&gt;&lt;/notifications-bell&gt;</code>, like so:</p>
  
  <pre><code>&lt;ion-navbar *navbar header-colour&gt;
    &lt;button menuToggle&gt;
      &lt;ion-icon name="menu"&gt;&lt;/ion-icon&gt;
    &lt;/button&gt;  
    &lt;ion-buttons end&gt;
      &lt;notifications-bell&gt;&lt;/notifications-bell&gt;
      &lt;button&gt;
        &lt;ion-icon name="add"&gt;&lt;/ion-icon&gt;
      &lt;/button&gt;
    &lt;/ion-buttons&gt;  
    &lt;ion-title&gt;Clients&lt;/ion-title&gt;
  &lt;/ion-navbar&gt;
  </code></pre>
  
  <p>But it's rendering with a background colour:</p>
  
  <p><a href="https://i.stack.imgur.com/FIYdS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FIYdS.png" alt="enter image description here"></a></p>
  
  <p><strong>Here's my component:</strong></p>
  
  <pre><code>import {Component} from 'angular2/core';
  
  @Component({
      selector: 'notifications-bell',
      directives: [],
      template: `&lt;button&gt;&lt;ion-icon name="notifications-outline"&gt;&lt;/ion-icon&gt;&lt;/button&gt;`
  })
  export class NotificationsBellComponent {
      constructor() {
      }
  }
  </code></pre>
  
  <p>Thanks.</p>
