当你在链接上不知道它所表示的意思的时候，ToolTip就比较有用了

<html>
<head>
<title>Tooltip Example</title>
<style type="text/css">
body {font-size: 85%; font-family: helvetica, verdana, arial, sans-serif;}
h1 {font-size: 1.3em;}
h2 {font-size: 1.2em;}
table { width: 70%; border-collapse: collapse;}
th {text-align: left;}
code {font-size: 1.1em;}
td { border: 1px solid #ccc; border-width: 1px 0; padding: 3px 6px;}

#livetip {
position: absolute;
background-color: #bfb;
padding: 4px;
border: 2px solid #9c9;
border-radius: 4px;
-webkit-border-radius: 4px;
-moz-border-radius: 4px;
}

</style>

</script>

<body>
<h1>Event Delegation Tooltip, with DRY script!</h1>
