响应式设计在桌面上调整大小，而不是在移动设备上

Question

我正在使用媒体查询来根据宽度调整网站元素的大小。我正在我的桌面上开发和测试它，它工作得很好，但是当我启动它并在移动设备（iPhone 5）上测试它时，它根本不会调整大小 - 它以全宽显示。

我已经四处寻找对此的回应，普遍的共识似乎是设置我的视口。但我已经这样做了——在我的标题中我有：

<meta name="viewport" content="width=device-width, initial-scale=1">

有什么我可能拥有的东西可以覆盖这个吗？

我的媒体查询如下所示：

@media (min-width:320px) { /* smartphones, iPhone, portrait 480x320 phones */ 
    #rlanguage {position: relative; right:0; border:red solid 0px;}
    #iX-nav {position: relative; right:0; border:red solid 01px;}
    #infoemail {display:none}
    #mainMenu {display:none}    
    #mobileMenu {display:inline}    
    #DeskTopOnly {display:none;}                            
    #MenuSpacing {width: 1px;}
    #iX-footer {width: 100%; height:auto}
    .GreenMenuLine {background:#000}                            
    .rootVoices TD.selected {padding: 0px;}
    .rootVoices TD.rootVoice {padding: 0px; width:10px}
}

}

提前致谢！

将您的第一个@media 最小宽度设置为 300 像素。 Iphone 5 大约 314 像素，这就是您的媒体查询不起作用的原因。
