What are the potential drawbacks of using JavaScript to handle screen resolution detection for design selection?

Using JavaScript for screen resolution detection can lead to inconsistencies and inaccuracies, as different browsers and devices may interpret the code differently. It's better to use server-side languages like PHP to handle this task, as it ensures a more reliable and consistent approach to design selection.

<?php
$screen_width = $_SERVER['HTTP_X_SCREEN_WIDTH'];

if ($screen_width < 768) {
    // Load mobile design
    include('mobile_design.php');
} else {
    // Load desktop design
    include('desktop_design.php');
}
?>
