title: PHP conditions depending on window width (media queries?)
body: <p>I have a responsive website and I need some PHP conditions depending on the windows width (or media queries).</p>
  
  <p>Example:</p>
  
  <pre><code>if ($window_width &gt; 1400px) {
      echo 'Your window is wider than 1400px';
  }
  
  elseif ($window_width &gt; 1000px) AND ($window_width &lt; 1399px) {
      echo 'Your window is between 1000px and 1399px';
  }
  
  else {
      echo 'Your window is narrower than 1000px.';
  }
  </code></pre>
  
  <p>Thanks for your help!</p>
