网页开发-问答题_显示题目-02

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>  
    <h1>Quiz</h1>  
    <div id="quiz"><!--此id用在main样式表中-->  
      <div id="question1">  
        <div class="question">Which is not a main file type that we use to make websites?</div>

     <script src="game.js"/>  
  </body>  
</html>  

 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
