Question

我认为如果条件不满足，条件评论会指示浏览器忽略内容？！

例如，如果IE6是浏览器，我想只包含一个样式表。以下位于＆lt; HEAD＆gt;页面的元素。

<!--[if IE 6]>
  <link id="IE6StyleSheet" rel="Stylesheet" type="text/css" href="~/css/IE6.css" runat="server" />
<![endif]-->

或

<!--[if IE 6]>
  <link rel="Stylesheet" type="text/css" href="../css/IE6.css" />
<![endif]-->

为什么IE7，IE8和FF3都加载了样式表？！

注意：将条件更改为[if lte IE 6]没有任何区别！：（

主要更新

我是个白痴......我只是注意到我做错了什么！我给出的例子略有修改。 App_Themes下的css文件路径！当然css总是加载!!!

尝试：

<!--[if lte IE 6]>
   <link id="IE6StyleSheet" rel="Stylesheet" type="text/css" href="../css/IE6.css" />
<![endif]-->

这只会加载IE6或更低版本的样式表。这是您可以使用的测试脚本，它将打印出您正在使用的IE版本：

<p><!--[if IE]>
According to the conditional comment this is Internet Explorer<br />
<![endif]-->
<!--[if IE 5]>
According to the conditional comment this is Internet Explorer 5<br />
<![endif]-->
<!--[if IE 5.0]>
According to the conditional comment this is Internet Explorer 5.0<br />
<![endif]-->
<!--[if IE 5.5]>
According to the conditional comment this is Internet Explorer 5.5<br />
<![endif]-->
<!--[if IE 6]>
According to the conditional comment this is Internet Explorer 6<br />
<![endif]-->
<!--[if IE 7]>
According to the conditional comment this is Internet Explorer 7<br />
<![endif]-->
<!--[if gte IE 5]>
According to the conditional comment this is Internet Explorer 5 and up<br />
<![endif]-->
<!--[if lt IE 6]>
According to the conditional comment this is Internet Explorer lower than 6<br />
<![endif]-->
<!--[if lte IE 5.5]>
According to the conditional comment this is Internet Explorer lower or equal to 5.5<br />
<![endif]-->
<!--[if gt IE 6]>
According to the conditional comment this is Internet Explorer greater than 6<br />
<![endif]-->
</p>

使用此测试代码，您不应在Firefox中看到任何文本。

当条件注释表明它应该被忽略时，为什么加载样式表？
