Problem changing link colors

[Shakarhaba]

I'm facing a problem changing the link colors:
Result: http://www.goear.com/upload/calendar.php (See the "Default Calendar" bar).
Also I would like to ask how I can change the RED line that indicates "today" I want to change its color.


css code:

  .linkUnderline{
  color:white;
  text-decoration:underline;
  font-family:Trebuchet MS, Verdana, Arial; 
  font-size:11px; 
  }
  .linkUnderline:link{
  text-decoration:underline;
  font-family:Trebuchet MS, Verdana, Arial; 
  font-size:11px; 
  color:white;
  }
  .linkUnderline:visited{
  text-decoration:underline;
  font-family:Trebuchet MS, Verdana, Arial; 
  font-size:11px; 
  color:white;
  }
  .linkUnderline:hover{
  text-decoration:underline;
  font-family:Trebuchet MS, Verdana, Arial; 
  font-size:11px; 
  color:white;
  }
  .linkUnderline:active{
  text-decoration:underline;
  font-family:Trebuchet MS, Verdana, Arial; 
  font-size:11px; 
  color:white;
  }

html code:

<div style="height:25px; width:825px; background-image:url($stylevar[imgdir_misc]/title_t.png);">
  <div style="float:left; width:285px; padding-left:8px; line-height:25px; font-family:Trebuchet MS, Verdana, Arial; font-weight:bold; font-size:11px; color:#FFF;">$calendarinfo[title]</div>
  <div style="width:810px; padding-left:8px; line-height:25px; text-align:right; font-family:Trebuchet MS, Verdana, Arial; font-size:11px; color:#FFF;">
    <table style="text-align:right; font-family:Trebuchet MS, Verdana, Arial; font-size:11px; color:#FFF;">
    <tr>
    <if condition="$show['popups']">
			<td style="color:#FFF"><a class="linkUnderline" href="calendar.php?$session[sessionurl]c=$calendarinfo[calendarid]&amp;month=$today[mon]&amp;year=$today[year]">$vbphrase[show_today]</a></td>

    </tr>
