panel caption text style

Hi all,
I am totally new to vaadin7. I need to change my Panel caption text color. Can anybody suggest any styling or other ways to achieve the same.

Currently for my Panel I am using the following in my styles.css


border-top: medium;
border-top-color: white;
border-left: medium;
border-left-color: white;
border-right: medium;
border-right-color: white;

.panelStyle .v-panel-caption
background: #335C77;
font-weight: bold;
font-style: normal;
height: 25px;
padding-left: 8px;
padding-top: 4px;
padding-bottom: 3px;
.panelStyle .v-panel-content
background: -moz-linear-gradient(top, #C0C0C0 0%, #EDEDED 10%);
background: -moz-linear-gradient(middle, #C0C0C0 10%, #EDEDED 100%);azimuth:
