当我在@media中替换背景图像时，IE9 +中不再显示背景图像。它可以在FF，Safari和Chrome中完美运行。我尝试了几次绕过，但似乎受这些限制的影响（见下文）。有人建议吗？

<div class="feature">
<ul class="feature-list">
<li class="nav-boat"><a href="/pages/disclaimer.php" ></a></li>
<li class="nav-camper"><a href="#"></a></li>
<li class="nav-tools"><a href="#"></a></li>
<li class="nav-cleaner"><a href="#"></a></li>

<li class="nav-car"><a href="#"></a></li>
<li class="nav-warehouse"><a href="#"></a></li>
<li class="nav-office"><a href="#"></a></li>

最佳答案
IE9不支持媒体查询，请在文本文件中的JS代码下方添加并保存为css-media-query-ie.js名称，然后将其添加至目录，然后在html页的开头添加以下标签。
的HTML
<head>
<!--[if lt IE 9]>
<script type="text/javascript" src="css-media-query-ie.js"></script>
<![endif]-->
</head>
css-media-query-ie.js

*/
var detectAndUseStylesheet = function(){
var currentWidth = screen.width,
// currentWidth = parseInt(document.documentElement.clientWidth),
//currentWidth = 320,
cssLinks = document.getElementsByTagName('link'),
_check = new RegExp(currentWidth, 'i'),
foundResolution = false,
allSupportedResolutions = [];
for(ii in cssLinks){
if(cssLinks[ii].href){
if(cssLinks[ii].id){
allSupportedResolutions.push(cssLinks[ii].id.match(/[0-9]+/i)[0]);
if(cssLinks[ii].id.match(_check)){
document.getElementById('stylesheet-'+currentWidth).removeAttribute('media');
foundResolution = true;
}
}
}
}
// Fallback if resolution is not found.
if(!foundResolution){
