仅限IE浏览器的CSS只影响IE中的页面，而不影响其他浏览器

我正在使用的网页在除IE以外的其他浏览器中工作正常。我正在使用IE 10（预览版），所以我可以使用阴影，而<br />不工作，所以我做了一个特定于IE的css，这样如果浏览器是IE，它就会加载IE的CSS。那么，当我去改变.homepagetable的页边距时，它也会将CSS应用到其他浏览器。 main.css和all-ie-only.css之间的区别是.homepagetable。仅限IE浏览器的CSS只影响IE中的页面，而不影响其他浏览器

警告：您的代码非常容易受到SQL注入攻击，并且存在许多其他明显的安全漏洞。另外，请注意'mysql_xxx（）'函数已被弃用;建议改为更新的'mysqli'或'PDO'库。 – SDC 2013-02-25 14:26:54

我还没有写完，它只是我的高级项目。我正在建立一个社交网络，它只是成为一种产品，并且可能不会在互联网上使用，除了一天之内没有任何重要的东西被存储。 @SDC – 2013-02-25 14:38:07

你是否使用了“ie-only样式表”？那里有很多。此外，只是一个提示：你不需要重复所有其他的东西。你可以有一个主样式表，然后一个用于IE的仅覆盖需要的内容 – naomi 2013-02-25 14:45:57

你一定要听@ SDC的有关安全漏洞的评论。这是一个比跨浏览器兼容性更重要的问题。

除此之外，你的代码是不工作，因为这样的：

<if !IE> 
<link href="css/main.css" rel="stylesheet" type="text/css"> 
<if IE> 
<link rel="stylesheet" type="text/css" href="css/all-ie-only.css" />

无效。

IE10应该符合与其他浏览器相同的标准。这听起来像IE10目前在怪癖模式下运行。在您的<html>应该解决问题之前立即丢弃<!DOCTYPE>。然后，你不需要使用你的条件。

如果你仍然停留在使用条件语句的想法，你可以试试：

<link href="css/main.css" rel="stylesheet" type="text/css"> 
<!--[if IE]> 
<link rel="stylesheet" type="text/css" href="css/all-ie-only.css" /> 
<![endif]-->

但是，这既包括main.css和all-ie-only.css。

我会尽力实施安全更新，但可能需要一些时间。对于''，我需要澄清它是什么类型的文件，如果是的话，我可以把php吗？感谢您的帮助。还有一个问题。 CSS中的阴影使文本与IE中搜索框的背景颜色相同，但在Chrome中它们不会。我该如何改变它？感谢您的答复。 – 2013-02-25 15:02:26

我去了开发者工具，并把它从怪癖中解救出来，因为即使我在'之前'有''，它仍然会加载怪癖 – 2013-02-25 15:13:10
