为什么不用通用的CSS3?

首页看节点... Firefox 12.0 还支持 -moz的

现在升级到Nightly 和 13.0 Beta 看节点居然不支持了

.item_node {
font-size: 12px;
line-height: 12px;
padding: 4px 10px 4px 10px;
margin: 0px 5px 5px 0px;
-moz-border-radius: 4px;
-webkit-border-radius: 4px;
display: inline-block;
background: #ffffff;
background: -moz-linear-gradient(top, #ffffff 0%, #f3f3f3 50%, #ededed 51%, #ffffff 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ffffff), color-stop(50%,#f3f3f3), color-stop(51%,#ededed), color-stop(100%,#ffffff));
background: -webkit-linear-gradient(top, #ffffff 0%,#f3ff3 50%,#ededed 51%,#ffffff 100%);
background: -o-linear-gradient(top, #ffffff 0%,#f3f3f3 50%,#ededed 51%,#ffffff 100%);
background: -ms-linear-gradient(top, #ffffff 0%,#f3f3f3 50%,#ededed 51%,#ffffff 100%);
background: linear-gradient(top, #ffffff 0%,#f3f3f3 50%,#ededed 51%,#ffffff 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#ffffff',GradientType=0 );
border: 1px solid #e5e5e5;
}
敢不敢加一个

border-radius: 4px;
