Bootstrap多分辨率所有布局内联媒体查询CSS,用于响应式设计,包括Android iphone和web asp.net

Question

我已经完成了一个网站,它现在在浏览器中运行良好.我被要求使其兼容Android,iPhone,iPad,平板电脑和网络等.我正在使用bootstrap asp.net.

现在我正在努力,找不到任何答案.我正在使用这些内联媒体查询

@media screen and (min-width:0px) and (max-width:320px){/*Any css will be defined here*/}
@media screen and (min-width:321px) and (max-width:480px){/*Any css will be defined here*/}
@media screen and (min-width:481px) and (max-width:540px){/*Any css will be defined here*/}
@media screen and (min-width:541px) and (max-width:775px){/*Any css will be defined here*/}
@media screen and  (min-width:768px) and (max-width:783px){/*Any css will be defined here*/}
@media screen and (min-width:776px) and (max-width:1536px){/*Any css will be defined here*/}
@media screen and (min-width:1537px){/*Any css will be defined here*/}

但在某些iPad中,CSS并未应用.现在我的问题是,@ media的标准分辨率和方向是什么,它将覆盖所有(Android,iPhone,平板电脑和Web等)CSS？
