I have a dropdown list that i would like to make transparent but I don't want it to effect the image and text in the list. I tried using

	opacity:0.6;
	filter:alpha(opacity=60); /* For IE8 and earlier */

Open in new window


but it make everything transparent.

Code is below

 <li>
                <a href="#">Assets</a>

                <ul class="subnav">
                    <li><a href="add_asset.php"><img src="images/navigation/add_asset.png" width='40' height='40' align='middle'/><br> Add Asset</a></li>
                    <li><a href="index.php?view=deploy"><img src="images/navigation/computer_deploy.png" width='40' height='40' align='middle'/><br> Assets Ready for Deployment</a></li>
                    <li><a href="index.php?view=restore"><img src="images/navigation/computer_restore.png" width='40' height='40' align='middle'/><br> Assets Needing to be Restored</a></li>
                    <li><a href="index.php?view=development"><img src="images/navigation/computer_development.png" width='40' height='40' align='middle'/><br> Development Machines</a></li>
                    <li><a href="index.php?view=unasigned"><img src="images/navigation/computer_unasigned.png" width='40' height='40' align='middle'/><br> Unasigned Assets</a></li>

                </ul>
            </li>

Open in new window


CSS

/*--Hover effect for trigger--*/
ul.topnav li ul.subnav {
	list-style: none;
	position: absolute;
	left: 0; top: 35px;
	background: #333;
	margin: 0; padding: 0;
	display: none;
	float: left;
	width: 170px;
	-webkit-border-bottom-right-radius: 05px;
	-webkit-border-bottom-left-radius: 5px;
	-moz-border-radius-bottomright: 05px;
	-moz-border-radius-bottomleft: 5px;
	border-bottom-right-radius: 05px;
	border-bottom-left-radius: 5px;
	border: 1px solid #111;
	z-index:2;
	opacity:0.6;
	filter:alpha(opacity=60); /* For IE8 and earlier */
}
ul.topnav li ul.subnav li{
	margin: 0; padding: 0;
	border-top: 1px solid #252525; 
	border-bottom: 1px solid #444; 
	clear: both;
	width: 170px;
	-webkit-border-bottom-right-radius: 05px;
	-webkit-border-bottom-left-radius: 5px;
	-moz-border-radius-bottomright: 05px;
	-moz-border-radius-bottomleft: 5px;
	border-bottom-right-radius: 05px;
	border-bottom-left-radius: 5px;
	z-index:2;

Try this for your CSS

html ul.topnav li ul.subnav li a{
background:url("http://i43.servimg.com/u/f43/14/73/12/96/dropdo10.gif") no-repeat scroll 10px center transparent;}

This is what I did and its works perfect in Chrome but in IE it shows nothing.

ul.topnav li ul.subnav {
      list-style: none;
      position: absolute;
      left: 0; top: 35px;
      background: rgba(0, 0, 0, .4) ;
      margin: 0; padding: 0;
      display: none;
      float: left;
      width: 170px;
      -webkit-border-bottom-right-radius: 05px;
      -webkit-border-bottom-left-radius: 5px;
      -moz-border-radius-bottomright: 05px;
      -moz-border-radius-bottomleft: 5px;
      border-bottom-right-radius: 05px;
      border-bottom-left-radius: 5px;
      border: 1px solid #111;
      z-index:2;

}
html ul.topnav li ul.subnav li a {
      float: left;
      width: 145px;
      background: rgba(0, 0, 0, .4) url(images/drop_down/dropdo10.gif) no-repeat 10px center;
      padding-left: 20px;
}
html ul.topnav li ul.subnav li a:hover { /*--Hover effect for subnav links--*/
      background: rgba(0, 0, 0, .4) url(images/drop_down/dropdo10.gif) no-repeat 10px center;
