title: How to disable zoom in mobile responsive?
body: <p>I have written this code for disabling zoom in or out:</p>
  
  <pre><code>&lt;meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" /&gt;
  &lt;meta name="HandheldFriendly" content="true" /&gt;
  </code></pre>
  
  <p>It is working fine in all mobile phones except in <strong>recent iphones</strong> (ex: iphone 6, iphone 7), where this function not working. Where did I make a mistake?</p>
