實現的困難在於：first-child,last-child 兩個選擇器，以後margin-left:-1px;的應用，33%,34%寬度的技巧處理。
另外一個困難是：box-shadow:1px 0 0 #F1F1F1 inset; 的實作。
最後是：
background:- webkit-gradient(linear, left top, left bottom, from(#f9f9f9), to(#b6b4b4));background:-moz-linear-gradient(top, #f9f9f9, #b6b4b4);background:-o-linear- gradient(top, #f9f9f9, #b6b4b4);background:linear-gradient(top, #f9f9f9, #b6b4b4);
