被百度这个 #usrbar 搞得有点郁闷了….

谁给出个主意?

从数据类型上看 貌似z-index最大也就65535了, 而space.css优先级又比自定义css要高
(space.css载入晚)

看这一段

html body center #usrbar{
    z-index:65535!important;                         /* 最大高度 */
    padding:4px 10px 3px 0!important;
    background:#FFFFFF!important;              /* 白色背景 */
    color:#000000!important;
    text-align:right!important;
    filter:alpha(opacity=65)!important;          /* 65% 透明度 */
    -moz-opacity:0.5!important;                     /* mozilla浏览器 50% 透明度 */
     width:auto!important
}

貌似已经覆盖不了他了…..
不知道哪位高人能想点其他办法出来? 前提是能支持 firefox && IE
