在上一节，编写main.css的时候，是把整个quiz隐藏起来了，而这里把隐藏的题目一个一个列举出来，

把main.css改为

body{
margin-left:50px;
}
#question1, #question2, #question3, #question4, #question5,
#question6, #question7, #question8, #question9, #question10
{
display:none;
}

 然后再编写一个文件game.js

if(jQuery){
$("#question1").show();
}

index.html内容如下

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Quiz</title>
<!--在本目录下，加入了main样式-->
<link rel="stylesheet" type="text/css" href="main.css">
</head>
<body>

 上方粗体，斜体是加在上一节代码里。

在main.css中，其他可以不用一个一个地隐藏，也可以使用类选择器。

上方的jquery.js在网上下载即可
