What best practices can be followed to prevent PHP website display issues across different browsers and devices?

PHP websites can experience display issues across different browsers and devices due to inconsistencies in how HTML and CSS are rendered. To prevent these issues, it is best to use responsive design techniques, such as using media queries to adjust styling based on screen size, and testing the website on multiple browsers and devices. 

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Responsive PHP Website</title>
    <style>
        /* CSS code for responsive design */
        @media only screen and (max-width: 600px) {
            /* styles for screens smaller than 600px */
        }
    </style>
</head>
<body>
    <?php
        // PHP code for website content
    ?>
