아래 두개 글자 진하게 나오게 하려면 어떻게 해야 하나요?

<td colspan="2"><a href="/board/list.php?bbs_id=notice" onfocus='this.blur();'><br>
                  <img src="img/a9.gif" width="237" height="37" border="0"></a></td>



 <tr>
                    <td><img src="img/a10.gif" width="11" height="4"></td>
                    <td width="226" height="20"><span class="s"><?=substr($rs[name],0,2)."★".substr($rs[name],4,2)?>    <?=titleCut($rs[pro], 25)?></span></td>
                  </tr>
<?}?>
