#panel {

background-color: #e9e9e9;
background-gradient-direction: vertical;
background-gradient-end: #d0d0d0;
border-top-color: #666; /* we don't supportnon-uniform border-colors and
use the top bordercolor for any border, so we
need to set iteven if all we want is a bottom
border */

border-bottom: 1px solid #666;
app-icon-bottom-clip: 0px;
color: transparent;  /*增加*/


/* hrm, still no multipoint gradients
background-image: linear-gradient(left,rgba(255, 255, 255, 0),
rgba(255, 255, 255, 1) 50%，rgba(255, 255, 255, 0)) !important;*/
}

#panel {
background-color:transparent;
font-weight: bold;

}


二、隐藏或删除底部panel

隐藏桌面图标，比如主文件夹和垃圾桶

应用程序——工具——优化工具——桌面

然后将需要隐藏的去掉勾选即可
