Hope this will help in someway. i need to add tooltip to the input with "#sendasgift" id. How to wrap this jquery to the proper hook and add properly to the functions.php without making a separate file

<table class="thwepo-extra-options  thwepo_simple" cellspacing="0">
  <tbody>
    <tr class="">
      <td class="value" colspan="2">
      <input type="checkbox" id="sendasgift" name="sendasgift" value="Yes" class="thwepof-input-field"> <label class="label-tag ">Send as gift</label>
      </td>
    </tr>
  </tbody>
</table>
