Question

我正在使用bootstrap来构建一个客户端的网站，当我尝试在移动设备上定位横向和纵向方向时，我已经失败了，以便为两个视口添加一些特定的样式。如何针对移动样式定位纵向和横向？我需要在320px断点处添加特定样式，在480px断点处添加某些样式。使用我当前的媒体查询，这不起作用目前在我的样式表中我有以下内容：

/* portrait phones */
@media only screen and (max-width: 320px) and (orientation:portrait) {
    /* Styles */
}

/* landscape phones */
@media only screen and (min-width: 321px) and (orientation:landscape) {
/* Styles */
    }

如果我把风格用于风景，但我不认为它们被拾取。每次我做出改变，然后刷新我的Iphone，我都没有看到任何区别。我想也许我的媒体查询错了？如果有更好的方法来定位移动状态，我将非常感谢任何帮助。

Answer 1

我设法最终通过为我的321px媒体查询添加最大宽度来解决此问题，并且能够同时定位横向和纵向移动方向。我还在我的标题中发现：[ { _id: "585be0da13385513689f704b", site: "NBT", url: "nbt.com", label: "NBT Home", platform: "desktop", speed: 75, date: "2016-12-22T14:15:57.975Z" }, { _id: "585be0da13385513689f704c", site: "MT", url: "m.mt.com", label: "MT Home", platform: "mobile", speed: 40, date: "2016-12-22T14:01:57.975Z" }, { _id: "585be0da13385513689f704d", site: "NBT", url: "m.nbt.com", label: "NBT Home", platform: "mobile", speed: 90, date: "2016-12-22T12:18:57.975Z" } ]似乎导致了问题，在删除它之后，我能够定位我需要的移动断点。
