I could if I had installed the mod.

Anyway, replace the code with:

<div class="tcat" colspan="3">
 Spoiler
</div>
<div style="background-color:#fff;color:#fff;border:1px solid #CCCFDD;cursor:pointer">
 <div class="spoiler" onmouseover="this.style.color='#000000';" onmouseout="this.style.color=this.style.backgroundColor='#ffffff'">
  {param}
 </div>
</div>

I added the cursor hand when hovering over the div.
