css制作京东的侧边栏导航

总结：

1.兼容ie6-7hover

可以下载

behavior:url(css/csshover.htc); csshover.htc文件

Firefox: -moz-

Chrome、Safari: -webkit-

Opera: -o-

IE: -ms-

3.设置边框外发光效果：

box-shadow: h-shadow(水平阴影的位置,必需) v-shadow(垂直阴影的位置,必需) blur(模糊距离,可选) spread(阴影的尺寸,可选) color(阴影的颜色,可选) inset(将外部阴影(outset)改为内部阴影,可选);

box-shadow:0 0 8px #ddd;

-moz-box-shadow:0 0 8px #ddd; //firefox

-webkit-box-shadow:0 0 8px #ddd; //google

4.总要的去除浮动栏之间缝隙

.menu li:hover  span{

background:#fff;

display:inline-block;

z-index:20px;width:20px;

height:30px;

float:right;

position:relative;

}

5. 巧用dl

.menu{

display:block;

width:220px;

border:2px solid #e4593c;

}

.titile{

height:40px;

line-height:40px;

text-indent:7px;

background:#e4593c;

}

}
