css - 使用 CSS 检测不同的设备平台

Question

我想说我已经阅读并尝试了这里的说明的许多变体：

我想让我的页面根据所使用的设备使用不同的 CSS 文件。我已经看到了很多解决方案，都使用上述的某种形式。

但是，在 HTC Desire 上进行测试时，我始终会得到用于 iPad 的输出或完全未经过滤的输出。目前，我的测试代码基于：

http://www.cloudfour.com/ipad-css/

这是我的 HTML 文件：

<html>
<head>
    <title>orientation and device detection in css3</title>

    <link rel="stylesheet" media="all and (max-device-width: 480px) and (orientation:landscape)" href="iphone-landscape.css" />
    <link rel="stylesheet" media="all and (max-device-width: 480px) and (orientation:portrait)" href="iphone-portrait.css" />

    <link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:landscape)" href="ipad-landscape.css" />
    <link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:portrait)" href="ipad-portrait.css" />

    <link rel="stylesheet" media="all and (device-width: 480px) and (device-height: 800px) and (orientation:landscape)" href="htcdesire-landscape.css" />
    <link rel="stylesheet" media="all and (device-width: 480px) and (device-height: 800px) and (orientation:portrait)" href="htcdesire-portrait.css" />

    <link rel="stylesheet" media="all and (min-device-width: 1025px)" href="desktop.css" />
</head>
<body>
    <div id="iphonelandscape">iphone landscape</div>
    <div id="iphoneportrait">iphone portrait</div>
    <div id="ipadlandscape">ipad landscape</div>
    <div id="ipadportrait">ipad portrait</div>
    <div id="htcdesirelandscape">htc desire landscape</div>
    <div id="htcdesireportrait">htc desire portrait</div>
    <div id="desktop">desktop</div>
</body>
</html>

这是 iPad 的 Landscape CSS 文件（我只在这里提供，因为它们基本相同：

div
{
    display: none;
}

#ipadlandscape
{
    display: inline;
}

我想知道要对链接元素进行哪些修改，以确保 ipad 仅获得其样式表，iphone 获得自己的样式表，并且（在这种情况下）htc 愿望（或相同分辨率/方面的设备）获得该样式表。

好吧，在玩了一些（更多）并添加了一些 javascript 之后，我得到了解决方案 - droid 设备没有使用我认为的分辨率：

    <link rel="stylesheet" media="all and (max-device-width: 480px) and (orientation:landscape)" href="iphone-landscape.css" />
