Link styles being over written in Opera

[KeredDrahcir]

I'm trying to create a menu using a list. I want it to look like lerge boxes with a graduated fill and it works fie on Firefox, Google Chrome, Safari and Internet Explorer my not Opera. In Opera the boxes come up in blue. Is this something to do with them being links and if so, how do I fix it?

<div class="mainmenu">
  <ul>
    <li class='menu'><a href='link' class='active'>Home</a></li>
    <li class='menu'><a href='link' class=''>Page</a></li>
      ...other pages
    <li class='menu'><a href='link' class=''>Page</a></li>
  </ul>
</div>

.mainmenu{
    background-color:#131b59;
    border: 1px solid #B9B3A4;
    border-radius: 8px 8px 8px 8px;    
}
.mainmenu ul{
    padding:0;
    margin:10px 0 10px 0;
    list-style:none;
}
.mainmenu li{
    padding:0 0 0 10px;
    margin:0 0 0 0;
    background:#131b59;
    background-image:-moz-linear-gradient(top,#815d39,#b08f66);
    background-image:-webkit-gradient(linear,left top,left bottom,from(#815d39),to(#b08f66));
filter:progid:DXImageTransform.Microsoft.Gradient(startColorStr=#815d39,endColorStr=#b08f66);
    height:35px;
    line-height:35px;
    text-align:left;
    border:1px solid #ffffff;
    border-bottom:1px #333333 solid;
}
.mainmenu li a{
    font-family:arial;
    font-size:13px;
    font-weight:bold;
    color:#FFFFFF;
    text-decoration:none;
} 
.mainmenu li:hover{
    background-image:-moz-linear-gradient(top,#f0ce42,#815d39);
    background-image:-webkit-gradient(linear,left top,left bottom,from(#f0ce42),to(#815d39));
filter:progid:DXImageTransform.Microsoft.Gradient(startColorStr=#f0ce42,endColorStr=#815d39);    
}

You have to use

background-image:-o-linear-gradient(top,#815d39,#b08f66);

for .mainmenu li

and

background-image:-o-linear-gradient(top,#f0ce42,#815d39);

for .mainmenu li:hover

-o-linear-gradient for Opera
-moz-linear-gradient for Mozilla
-webkit-gradient for webkit (Chrome, Safari)

Hope it's help you. :)
