title: Click to call html
body: <p>I want to use html5 tag in my website for mobile view when user click on this link from mobile device it will place a call on the given number.. </p>
  
  <pre><code>&lt;p&gt;Book now, call &lt;a href="tel:01234567890"&gt;01234 567 890&lt;/a&gt;&lt;/p&gt;
  </code></pre>
  
  <p>What should I do to hide this link when user mobile is non html5.. 
  I have gone through modenizer but seems it will not detect the link attribute.

  <p>Any suggestion? 
  This button will only appear when my website is opened on mobile device and for mobile devices I want to hide this link when opened in old mobile.. </p>
