The @media query appears to be functioning properly, however, it is not producing the

Conducted a basic test on @media queries to determine functionality:

Visit the test page here

I have set up a @media query in test.css that is supposed to change the background color from black to red on landscape tablets (1024x768). The CSS and XHTML are both valid, but for some reason, the background remains black in Firefox using Chris Pederick's Web Developer Extension -> View Responsive Layouts, as well as in the transmog.net iPad emulator (I do not own an iPad).

If anyone can shed light on why it’s not functioning properly, I’m excited to dive deeper into media queries.

Answer №1

First and foremost, these breakpoints are unparalleled

 @media (min-width:320px) { /* smartphones, iPhone, portrait 480x320 phones */ }
 @media (min-width:481px) { /* portrait e-readers (Nook/Kindle), smaller tablets @ 600 or        @ 640 wide. */ }
 @media (min-width:641px) { /* portrait tablets, portrait iPad, landscape e-readers, landscape 800x480 or 854x480 phones */ }
 @media (min-width:961px) { /* tablet, landscape iPad, lo-res laptops and desktops */ }
 @media (min-width:1025px) { /* big landscape tablets, laptops, and desktops */ }
 @media (min-width:1281px) { /* hi-res laptops and desktops */ }

For your specific scenario, employ this media query instead 

 @media (max-width:1024px)  {
html, body { 
    background-color: #f00;
    color:#000;
     }
}

Answer №2

Your media query needs to be corrected; using max-device-width is not valid, you should use max-width instead. 

<!DOCTYPE html>
<html>
<head>
    <title>Page Title</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;">
    <meta name="apple-mobile-web-app-capable" content="yes" />
    <style type="text/css">
        html, body {
            height: 100%;
            font-size: 12px;
            text-align: left;
            margin: 0;
            padding: 5px;
            background-color: #000;
            font-family: verdana,arial,geneva,helvetica,sans-serif;
            color: #fff;
            text-align: center;
        }
        /* For iPad and other tablets in landscape mode */
        @media screen and (max-width: 1024px) {
            html, body {
                background-color: #f00;
                color: #000;
            }
        }
    </style>
</head>
<body>
    <h1>Why isn't the background red on iPad in landscape mode at 1024px width??</h1>
</body>
</html>

Answer №3

It appears that utilizing "@media only screen and (max-width: 1024px)" is effective as well.
