</html>这是所给的源代码代码中可见，before与after两个伪元素颜色不一样，前面一个li的after与下一个li的before组合成为一条分割线。如果用li:hover伪类实现的话，只能显示当前li的after和before伪元素如果我要实现两边都有分割线出现的效果，该怎样？难点：之前做过分割线效果利用空元素的border来实现，但是无法实现渐变效果。如果通过建立伪元素进行background渐变的方式，无法实现两条线同时显示。

你这种情况就是属于本来只有6个导航项 但是要显示7条分割线 所以可以在nav后面加个伪类
.nav:after{
right:27px;
background: -moz-linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a);
background: -webkit-linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a);
background: -o-linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a);
background: -ms-linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a);
background: linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a);
}

.nav li:first-child::before{
display: none;
}
.nav li:last-child::after{
display: none;
}去掉两边的也挺好，反正没东西~~已参考下
