Detect different device platforms using CSS

StackOverflow https://stackoverflow.com/questions/8037973

Question

I'd like to say that I have read and tried many variations of the instructions here:

I would like to have my page use different CSS files depending on the device being used. I have seen many solutions to this, all using some form of the above.

However, when testing on an HTC Desire I consistently get either the output intended for iPad or a completely unfiltered output. Currently, my test code is based on:

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

Here is my HTML file:

<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>

And here is the iPad's Landscape CSS file (I'll only provide that here as they are all basically the same:

div
{
    display: none;
}

#ipadlandscape
{
    display: inline;
}

I would like to know what modifications to make to the link elements to ensure that the ipad gets only its stylesheets, the iphone gets its own and (in this case) the htc desire (or same resolution/aspect devices) get that stylesheet.

Was it helpful?

Solution

Well, after some (much more) playing around and the addition of some javascript, I've got the solution - the droid device was not using the resolution I believed it was:

<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>
