html - Color on current page (asp.NET masterpage) -

i'm going deliver website school-project tomorrow , while i'm going on bugs found out increase level of user-friendliness should change color of active page in header.

i know how can in basic html-site, i've used asp.net master-page , after understand bit different time since not have access links other stylesheets masterpage.css

so simplify question:

i got a:hover on links change color when hover on them, want link of active page in color show user @ times (not a:visited).

here code:

    <nav class="navmain">             <ul>                 <li><a class="a_home" href="default.aspx">hjem</a></li>                 <li><a href="kampanje.aspx">om konkurransen</a></li>                 <li><a href="default.aspx"><img id="navpic" src="pictures/header/munch150.png" alt="munch logo" /></a></li>                 <li><a href="bildegalleri.aspx">bidrag</a></li>                 <li><a href="infoside.aspx">om oss</a></li>             </ul>      </nav> 

and css:

    .navmain { position: relative; bottom: 43px; right: 80px; height: 25px; width: 1000px; z-index: 100; 

}

.navmain #navpic {     position: relative;     top: 93px;     width: 120px;     height: 125px; }  .navmain {     text-decoration: none;     color: black;     font-size: 1.5em; }      .navmain a:hover {         color: rgb(255, 255, 255);     }    .navmain li {     list-style: none;     display: inline;     padding-left: 5em; }  .navmain ul {     width: 1000px; } 

hoping fast response, thanks!
