negative selector
:not is a negative selector, which can filter out elements that do not want to be matched. The code example is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset=" utf-8">
<meta name="author" content="//m.sbmmt.com/" />
<title>php中文网</title>
<style type="text/css">
ul li{}
input:not(:disabled){
color:green;
}
</style>
</head>
<body>
<ul>
<li><input type="text" value="php中文网"/></li>
<li><input type="text" disabled value="php中文网"/></li>
</ul>
</body>
</html>
