<p>As the title's saying, I can't set media screen width-specific CSS for my PHP webpage.</p> <p>Here is my <code><head></code> section of my <code>index.php</code>:</p> <pre><code><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title><?php echo SITENAME; ?> - <?php echo SITEDESC; ?></title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0; minimumscale=1.0, maximum-scale=1.0; user-scalable=0;" />   <script type='text/javascript' src='scripts/respond.min.js'></script>  <link type="text/css" rel="stylesheet" href="style.css"/> </head> </code></pre> <p>For my HTML element <code><header> ... </header></code>, in my CSS (in <code>style.css</code>), I specified:</p> <pre><code>header{ background: #1e5799; min-height: 40px; max-height: 136px; } </code></pre> <p>But using "Web Developer" toolbar's <em>Resize</em> » <em>View Responsive Layouts</em> is showing some fall in different width device layouts.</p> <p>For example:<br/> In my <code><header></code> tag, the inner elements are getting out, so I need to increase the height of the header. So I specified in <code>style.css</code>:</p> <pre><code>/* Media Queries for Different Types of Mobile Devices */ /* Mobile portrait (320 x 480) */ @media all and (max-device-width: 320px) { header{ height: 136px !important; background-color: #FF0000; } } </code></pre> <p>But it's not working. :(</p> <p>What am I missing about responsive CSS?</p> <h3>EDIT</h3> <p>After the first 2 answers, with their suggestions, I tried using:</p> <pre><code>@media screen and (max-width: 320px) { header{ height: 136px !important; background-color: #FF0000; } } </code></pre> <p>And yes, I put my media CSS at the bottom of <code>style.css</code>.</p> <p>I also tried separating the <code>mobile.css</code> as:</p> <pre><code><link type="text/css" rel="stylesheet" media="screen and (max-device-width: 480px)" href="css/mobile.css" /> </code></pre> <p>Where I tried placing the following code:</p> <pre><code>header{ height: 130px; } </code></pre> <p>Still it's not working.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
