Display:block not working on sub-links (urgent!)

Hi guys, I want forum's sub-links to be in seperate rows instead of being in one. 
So instead of this:
link1 link2 link3 link4

I want it to be:
link1
link2
link3
link4

I've tried adding display:block in my css but it doesn't seem to do the trick. 

Here is my index_box template:

Code:

<table width="100%" border="0" cellspacing="1" cellpadding="0" align="center">
   <tr>
      <td valign="bottom">
         <!-- BEGIN switch_user_logged_in -->
         <span class="gensmall">{LAST_VISIT_DATE}<br />
         {CURRENT_TIME}<br />
         </span>
         <!-- END switch_user_logged_in -->
         <div class="nav"><a class="nav" href="{U_INDEX}">{L_INDEX}</a>{NAV_CAT_DESC}</div>
      </td>
      <td class="gensmall" align="right" valign="bottom">
         <!-- BEGIN switch_user_logged_in -->
         <a class="gensmall" href="{U_SEARCH_NEW}">{L_SEARCH_NEW}</a><br />
         <a class="gensmall" href="{U_SEARCH_SELF}">{L_SEARCH_SELF}</a><br />
         <!-- END switch_user_logged_in -->
         <a class="gensmall" href="{U_SEARCH_UNANSWERED}">{L_SEARCH_UNANSWERED}</a>
      </td>
   </tr>
</table>
<!-- BEGIN catrow --><!-- BEGIN tablehead --><table class="forumline" width="100%" border="0" cellspacing="0" cellpadding="0">
     <tr>
      <th colspan="4" nowrap="nowrap" width="100%" class="secondarytitle">{catrow.tablehead.L_FORUM}</th>
   </tr>
   <!-- END tablehead -->
   <!-- BEGIN cathead -->
   <tr>
      <!-- BEGIN inc -->
      <td class="{catrow.cathead.inc.INC_CLASS}" width="46"><img src="{SPACER}" height="0" width="46" /></td>
      <!-- END inc -->
      <td class="{catrow.cathead.CLASS_CAT}" colspan="{catrow.cathead.INC_SPAN}" width="100%">
         <h{catrow.cathead.LEVEL} class="hierarchy">
            <span class="cattitle">
               <a class="cattitle" title="{catrow.cathead.CAT_DESC}" href="{catrow.cathead.U_VIEWCAT}">{catrow.cathead.CAT_TITLE}</a>
            </span>
         </h{catrow.cathead.LEVEL}>
      </td>
      <td class="{catrow.cathead.CLASS_ROWPIC}" colspan="4" align="right">&nbsp;</td>
   </tr>
   <!-- END cathead -->
   <!-- BEGIN forumrow -->
   <tr>
      <!-- BEGIN inc -->
      <td class="{catrow.forumrow.inc.INC_CLASS}" width="46"><img src="{SPACER}" height="0" width="46" alt="." /></td>
      <!-- END inc -->
      <td class="{catrow.forumrow.INC_CLASS}" align="center" valign="middle">
                  <div class="nimg">

                  </div>
          </td>
      <td class="row1 over" colspan="{catrow.forumrow.INC_SPAN}" valign="top" width="100%" height="50">
                          <div class="desc1">

      </td>
   </tr>
   <!-- END forumrow -->
   <!-- BEGIN catfoot -->
   <tr>
      <!-- BEGIN inc -->
      <td class="{catrow.catfoot.inc.INC_CLASS}" width="46"><img src="{SPACER}" height="0" width="46" /></td>
      <!-- END inc -->
      <td class="spaceRow" colspan="{catrow.catfoot.INC_SPAN}" height="1"><img src="{SPACER}" alt="" height="1" width="1" /></td>
   </tr>
   <!-- END catfoot -->
   <!-- BEGIN tablefoot -->
</table><img src="{SPACER}" alt="" height="5" width="1" /><!-- END tablefoot --><!-- END catrow -->

And this is the css:

Code:

.nimg {
  margin-top:10px;
}

.mlinkai1 {
  display:block;
  height:116px;
  margin-top:10px;
  width:200px;
  background-color:#050505;
}

.mlinkai2 {
  color:#050505;
  width:190px;
  padding-top:50px;
  height:50px;
  overflow:auto;
  text-transform:uppercase;
  font-size:10px;
}

.desc1 {
  height:74px;
  margin-top:10px;
  width:400px;
  background-color:#050505;
}

.desc3 {
  margin-top:-14px;
  width:380px;
  margin-left:10px;
  height:1px;
  border-bottom: dashed 1px;
} 
  
.desc2 {
  width:380px; 
  padding-left:10px;
  height:45px;
  overflow:auto;
  margin-top:5px;
  font-family:times new roman;
  line-height:120%;
  text-transform:uppercase;
  font-size:7px; 
  letter-spacing:1px; 
  text-align:justify;
}

Hello @Julija,

Try using the direct child ( > ) and wildcard ( * ) selectors to render the direct children of the subnav as block-level elements.

Code:

div.nav > * { display:block }

Worked like a charm. Thanks!!
