Using the Negation Selector
Description
The negation selector inverts any selection.
Example
The following code shows how to use the Negation Selector.
<!DOCTYPE HTML>
<html>
<head>
<style type="text/css">
a:not ([href*="java2s"] ) {
border: thin black solid;
padding: 4px;
}<!--from w w w.ja v a 2s .c om-->
</style>
</head>
<body>
<a href="http://java2s.com">Visit the website</a>
<p>
I like <span>CSS</span> and HTML.
</p>
<a href="http://w3c.org">Visit the W3C website</a>
</body>
</html>
This selector matches all a elements that don't have
an href element that contains the string java2s.
