我已经尝试了在不同网站上看到的几种条件格式，但似乎无法让它发挥作用。浏览器版本为IE 11。
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="description" content="">
<meta name="author" content="">
<title></title>
<link href="CSS/reset.css" rel="stylesheet" />
<link href="css/bootstrap.min.css" rel="stylesheet" />
<link href="CSS/font-awesome.css" rel="stylesheet" />
<!--[if !IE]><!--><link rel="stylesheet" type="text/css" href="CSS/login.css" /><!--<![endif]-->
<!--[if IE]><!--><link rel="stylesheet" type="text/css" href="CSS/loginIE.css" /><!--<![endif]-->
我已经改变了格式。删除 Bootstrap 和 Fontawesome CSS 但仍然无法正常工作。我什至更改/删除了文档类型和元值，但没有任何效果。请帮忙。
最佳答案
IE10+没有条件注释，看看here
Support for conditional comments has been removed in Internet Explorer 10 standards and quirks modes for improved interoperability and compliance with HTML5. This means that Conditional Comments are now treated as regular comments, just like in other browsers. This change can impact pages written exclusively for Windows Internet Explorer or pages that use browser sniffing to alter their behavior in Internet Explorer.
您可以尝试对 IE10 和 IE11 使用 IE hack
像这样:
/*IE10 and IE11*/
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
.selector { property:value; }
}
关于html - IE11 条件 CSS 注释不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39473879/
