need to get browser at first by writing javascript code
var browser=navigator.appName //get Browser name
and then set the opacity for different browsers
if(browser=="Netscape") //For mozilla firefox
{
document.getElementById('layout').style.opacity = .7;
}
if(browser=="Microsoft Internet Explorer")
{
document.getElementById('layout').style.filter:alpha(opacity=70); /* IE 5-7 */
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=70)";
}
