E[attr|="value"] selector

This selector can match elements that have the attr attribute and the attribute value is "value" or starts with "value-". The code example is as follows:

<!DOCTYPE html>
<html>
<head>
<meta charset=" utf-8">
<meta name="author" content="http://ask.php.cn/" />
<title>php中文网</title>
<style type="text/css">
li{
  list-style:none;
  float:left;
  height:20px;
  line-height:20px;
  width:20px;
  border:1px solid #333;
  border-radius:10px;
  border-radius:10px;
  border-radius:10px;
  text-align:center;
  color:green;
  margin-right:5px;
}
li[id|="ant"]{
  color:red;
}
</style>
</head>
<body>
<div class="antzone">
  <ul>
    <li>1</li>

    <li>7</li>
