I think my problem is simple to resolve but i didn't find anything related to this. I just want to add a class id when i use JQuery replace.

Here i'm using this small script :

<script>
  $("body").html($("body").html().replace(" <strong>Mario</strong> game" , " <span class="class-id"><strong> Mario</strong> bros."));
  </script>

Can you help me? Thanks
