E[attr^="value"] selector

This selector can match elements whose attribute value starts with the specified content. 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^="an"]{
  color:red;
}
</style>
</head>
<body>
<div class="antzone">
  <ul>
    <li>1</li>
    <li>2</li>
    <li id="antzone">3</li>
    <li id="bntzone">4</li>
    <li>5</li>
    <li>6</li>
    <li>7</li>
    <li>8</li>
    <li>9</li>
  </ul>
</div>
</body>
</html>

The above code can set the font color in the element whose id attribute starts with an to red.
Of course, multiple selectors can also be used together. The code is as follows:

li[id^="an"][title^="com"]{
  color:red;
}
