Question

我的index.php包含一堆php和javascript代码，以及用CSS格式化的html。我对CSS不是很有经验，但我不认为它会影响这个html表单的可用性。这是索引代码：

<!DOCTYPE html "-//W3C//DTD XHTML 1.0 Strict//EN" 
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
    <title>Untitled</title>
    <meta name="description" content="Choose"/>
    <meta name="keywords" content="choose "/>
    <link rel="shortcut icon" href="http://i/favicon.ico"> 

    <!--[if lt IE 7]>
        <script type="text/javascript" src="FullPageBackgroundImage/js/mootools.js"></script>
        <script type="text/javascript" src="FullPageBackgroundImage/js/core.js"></script>
    <![endif]-->


<link rel="stylesheet" type="text/css" href="style.css" />

</head>

<body>

<div id="content">
<div id="poll">
<form>

<input id="ch1" type="radio" name="choice" value="0" />
<label for="ch1">
<?php echo $current['choice1']; ?>
</label>
<br />
<input id="ch2" type="radio" name="choice" value="1" />
<label for="ch2">
<?php echo $current['choice2']; ?>
</label>
</form>
</div>
hello

</div>

</body>
</html>

这就是CSS：

/*conten*/
#content{
    position:relative;
    top:55px;
    z-index:-3;
}

有了这个，我只能选择第二个单选按钮，第一个单选按钮无法选择。奇怪的是，如果我删除输入之间的中断，它的工作完美。或者我可以在那里休息，并在表格后删除'helloworld'，它也可以。

任何人有任何想法或看到任何错误？我想把按钮放在彼此的顶部，我需要在下面有其他文字..

CSS代码在这里

Answer 1

为什么你有z-index:-3？您告诉浏览器将内容放在其他图层后面......

Answer 2

CSS几乎绝对是错误的。看起来有一个正在被选中的子节点（<br />），当你不理解它时。也可以从Javascript发生。

Html表单单选按钮不起作用
