在修复了调用它的 HTML 被我使用它的网站破坏后，我至少设法让关闭状态正确显示。但是幻灯片根本不会打开。这是CSS：

/**

article, aside, details, figcaption, figure, footer, header, hgroup, nav, section { display: block; }
audio, canvas, video { display: inline-block; *display: inline; *zoom: 1; }
audio:not([controls]) { display: none; }

    vertical-align:top;
    margin-right:10px;
}

.accordion div{
    display:inline-block;
    width:311px;
}

这是HTML：

<!doctype html>
<html>
<head>
<link rel="stylesheet" href="http://static.tumblr.com/fq90l5c/7mhmmh2t0/style.css" /> 
<!--[if IE 8]>
<script src="http://static.tumblr.com/fq90l5c/2Csmn937d/html5shiv.js"></script>
<![endif]-->
</head>
<body>
<div class="accordion vertical"><section id="vertabout">
<h2><a href="#vertabout">Tutor-Led Course</a></h2>
<img src="image" height="146" width="211" />
<div>To view the tutor-led course information, please click <a href="link">here</a></div>
</section><section id="vertservices">

<div>To view the E-Learning course information, please click <a href="link">here</a></div>
</section></div>
</body>
</html>

谁能明白为什么这在 IE8 中不起作用？我已经用 Firefox 对其进行了测试，它工作得很好。

这里的主要问题是:target伪类仅在 IE9+ 中受支持。另一个会影响显示的问题是这些转换不会在 IE8 中呈现，但是，这可能只会影响手风琴的工作情况，而不是导致它根本无法工作。

IE8 不支持 CSS 选择器 :target 和 :nth-child。您可以使用 polyfill 添加对 IE8 用户的支持（就像您通过添加对 HTML5 的支持一样html5shiv.js）。

我经常（阅读：总是）在我的项目中包含Selectivizr，以在 IE6-8 中创建对此类选择器的支持。
