你好 friend ，请帮助我，我已经使用了所有方法，但响应式设计在 IE 中不起作用。我什么都用了。我还使用了 css-mediaqueries.js。这是行不通的，请帮助我
这里我给你我的示例 html 页面:
<!DOCTYPE html>
<!--[if IE 7 ]><html class="ie7" lang="en"><![endif]-->
<!--[if IE 8 ]><html class="ie8" lang="en"><![endif]-->
<!--[if IE 9 ]><html class="ie9" lang="en"><![endif]-->
<!--[if !IE]><!--> <html> <!--<![endif]-->
<head>
<!-- Meta -->
<meta charset="utf-8">
<meta name="keywords" content="" />
<meta name="description" content="">
<meta name="author" content="">
<title>Ads View Page</title>
<!-- Mobile Meta -->
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!--[if IE]>
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<![endif]-->
<!-- css -->
<link rel="stylesheet" href="inc-media/bsm_style.css">
<link rel="stylesheet" href="inc-media/responsive.css">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<!--[if lt IE 9]>
<script src="inc-media/html5shiv.js"></script>
<script src="inc-media/respond.js"></script>
<![endif]-->
</head>
<body>
<header></header>
</body>
</html>
这是我的响应式和主 Css 响应式 CSS
@charset "utf-8";
/* CSS Document */
@media screen and (min-width: 768px) and (max-width: 979px) {
header{ background:#FF0000!important;
}
}
@media screen and (max-width: 767px) {
header{ background:#069!important;}
}
@media screen and (max-width: 480px) {
header{ background:#36F!important;}
}
主CSS

请告诉我我的 friend 们我错过了什么。
最佳答案
在您的 !important 和实际值之间放置空格。
@media screen and (min-width: 768px) and (max-width: 979px) {
header{
background:#FF0000 !important;
}
}
@media screen and (max-width: 767px) {
header{
background:#069 !important;
}
}
@media screen and (max-width: 480px) {
header{
background:#36F !important;
}
}
此外，如果您以更好的方式编码——“移动优先”——更好的做法是为您的 IE7 和 IE8 浏览器提供移动 View ，而不使用 JS 作为默认浏览器。 @Jefferson-Ribeiro 的链接中推荐了这种做法。它会正常工作。
