#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;*/
