title: ionic 2 - Remove Border Footer
body: <p>I have a blue footer like this</p>
  
  <pre><code>&lt;ion-footer align="center"&gt;
    &lt;ion-toolbar&gt;
      &lt;ion-title&gt;
  ...
  </code></pre>
  
  <p>But it is showing a shadow style border at the top. How can I remove it. I tried to inspect it but did not find anything.</p>
