In daily development, we often encounter that the last li in the loop is different from other li. To remove a certain css style, this article introduces the use of the new :not() pseudo-class selector in CSS3 to achieve It is very convenient to use. Friends who are interested can come and take a look below.

<style type="text/css"></p>
<p>/*

*/
html { 
 -moz-osx-font-smoothing: grayscale; 
 -webkit-font-smoothing: antialiased; 
 text-rendering: optimizeLegibility; 
}</p>
<p>/*
    给body添加阴影
*/
body:before {
 content: "";
 position: fixed;
 top: -10px;
 left: 0;
 width: 100%;
 height: 10px;
 -webkit-box-shadow: 0px 0px 10px rgba(0,0,0,.8);
 -moz-box-shadow: 0px 0px 10px rgba(0,0,0,.8);
 box-shadow: 0px 0px 10px rgba(0,0,0,.8);
 z-index: 100;
}</p>
<p>/*
 设置列表
*/
.listItem {
    border: 1px solid red;
}
.listItem ul {
    width: 100%;
    overflow:hidden;
}
.listItem ul,listItem li {
    margin:0;
    padding:0;
    list-style:none;
}
.listItem li {
   margin-left:10px;
}
/*
    li 最后一个元素不添加边框
*/
.listItem li:not(:last-child) {
    border-bottom:1px solid green;  
}
/*
    与第一个li相连兄弟
*/
.listItem  li:first-child ~ li { border-left: 1px solid #666; }
</style>
</head></p>
<p><body></p>
<p> <p class="listItem">
     <ul>
            <li>列表1</li>
            <li>列表2</li>
            <li>列表3</li>
            <li>列表4</li>
            <li>列表5</li>
        </ul>
    </p>
</body>
