Question

我想说我已阅读并尝试了许多指令变体：

我希望我的页面使用不同的CSS文件，具体取决于所使用的设备。我已经看到了许多解决方案，都使用了上述的某种形式。

然而，当在HTC Desire上进行测试时，我始终获得用于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;
}

我想知道对链接元素进行了哪些修改以确保ipad只获取其样式表，iphone获得自己的（在这种情况下）htc欲望（或相同的分辨率/方面设备）获得样式表。

好吧，经过一些（更多）玩游戏并添加了一些javascript后，我得到了解决方案 - 机器人设备没有使用我认为的分辨率：

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

    <link rel="stylesheet" media="all and (max-device-width: 480px) and (orientation:portrait)" href="iphone-portrait.css" />
    <link rel="stylesheet" media="all and (max-device-width: 480px) and (orientation:landscape)" href="iphone-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: 768px) and (device-height: 1024px) and (orientation:landscape)" href="ipad-landscape.css" />
    <link rel="stylesheet" media="all and (device-width: 800px) and (device-height: 1184px) and (orientation:portrait)" href="htcdesire-portrait.css" />
    <link rel="stylesheet" media="all and (device-width: 800px) and (device-height: 390px) and (orientation:landscape)" href="htcdesire-landscape.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>
    <script type="text/javascript">
        function res() { document.write(screen.width + ', ' + screen.height); }
        res();
    </script>
</body>
</html>
