Question

修复调用它的HTML被我正在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; }

这是HTML：

<!--[if IE 8]>

<![endif]-->
</head>
<body>
<div class="accordion vertical"><section id="vertabout">

任何人都可以看到为什么这在IE8中不起作用？我已经用Firefox测试了它，它的工作正常。

Answer 1

这里的主要问题是只在IE9 +中支持:target伪类。影响显示的另一个问题是那些转换不会在IE8中呈现，但是，这可能只会影响手风琴的工作效果，而不是它根本不起作用的原因。

Answer 2

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（就像通过html5shiv.js添加对HTML5的支持一样）。

我经常（读取：总是）在我的项目中包含Selectivizr，以便在IE6-8中为这些选择器创建支持。

这个CSS手风琴在IE8中不起作用的原因是什么？
