Detailed explanation of usage examples of CSS3 :not() pseudo-class selector
CSS3’s new :not() pseudo-class selector matches elements that do not contain selectors. Suppose there is a list. Each list item has a bottom line, but the last item does not need a bottom line. The case is as follows:
<!DOCTYPE>
<html>
<head>
<meta charset="utf-8" />
<title>使用:not() 最后一行li不添加边框</title>
<style type="text/css">
/*
使字体在所有设备上都达到最佳的显示
*/
html {
-moz-osx-font-smoothing: grayscale;
-webkit-font-smoothing: antialiased;
text-rendering: optimizeLegibility;
}
/*
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;
}
/*
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>
<body>
<p class="listItem">
<ul>
<li>列表1</li>
