How can CSS styles be applied to PHP-generated content for better visual presentation?

To apply CSS styles to PHP-generated content for better visual presentation, you can use inline styles or link an external CSS file to your PHP file. Inline styles can be added directly to the HTML elements generated by PHP, while linking an external CSS file allows you to define styles in a separate file and apply them to the PHP-generated content.

<!DOCTYPE html>
<html>
<head>
    <title>PHP Generated Content with CSS</title>
    <style>
        /* Define CSS styles here */
        .php-content {
            color: #333;
            font-size: 16px;
            font-family: Arial, sans-serif;
        }
    </style>
</head>
<body>

<?php
// PHP code to generate content
$php_content = "This is PHP-generated content with CSS styles applied.";

// Output the content with CSS class
echo "<div class='php-content'>$php_content</div>";
?>

</body>
</html>
