carlucci Hi. To override the style You can use higher priority code like:
#container .item.hilite:hover .item-inner {
background: #fff;
border-color: #DAD9CF;
color: #666;
}
to add shadow on hover try with this code:
#container .item:hover .item-inner {
border-color: #333;
box-shadow: 0 0 5px rgba(0,0,0,.7);
}
