如何在Golang HTML模板中使用算术运算符

I want to compare field 'FileSize' in my html go temple with variable 'minsize' in my code (.FileSize < *minsize). I have no idea how to do it. See below

{{ if lt .FileSize *minsize }}
<td style="color:red;">{{.FileSize}}</td>
{{else}}
<td>{{.FileSize}}</td>
{{end}}

    Akama Razor tells me, that you don't need to use GO code here. it's much better to use JS in such situation.

    Good luck! 

    s = document.getElementsByTagName('td');

for (i = 0; i < s.length; i++) {
  if (parseInt(s[i].innerText) > 123) {
    s[i].style = 'color:red';
  }
}
    <head lang="en">
  <title>123</title>
</head>

<body>
  <table>
    <tbody>
      <tr>
        <td>123</td>
        <td>1234</td>
      </tr>
    </tbody>
  </table>
  <script>
    s = document.getElementsByTagName('td');
    for (i = 0; i < s.length; i++) {
      if (parseInt(s[i].innerText) > 123) {
        s[i].color = '#fff';
      }
    }
  </script>
</body>

    </div>
