title: Add strong tag only to the elements of a class
body: <p>I would like to find a way in which all the "titolonuovo" classes have the strong tag, not so much for the bold as for an effect that I assigned to the strong tag. Do you know a way with jquery?</p>
  
  <pre><code>   &lt;h2 class="titolonuovo"&gt;&lt;strong&gt;xxxxxxxxx&lt;/strong&gt;&lt;/h2&gt;
      &lt;h2 class="titolonuovo"&gt;yyyyyyyyy&lt;/h2&gt;
      &lt;h2 class="titolonuovo"&gt;zzzzzzzzz&lt;/h2&gt;
  
  jQuery( document ).ready(function() {
    if (jQuery('h2').hasClass("titolonuovo")) {
  //WHAT SHOULD I DO HERE
  });
  </code></pre>
