Are there any common pitfalls to avoid when working with JSON data in PHP and using CSS classes to style values?

One common pitfall when working with JSON data in PHP and using CSS classes to style values is not properly escaping the data before outputting it to the HTML. This can lead to security vulnerabilities such as cross-site scripting (XSS) attacks. To avoid this, make sure to use functions like htmlspecialchars() to escape the JSON data before inserting it into the HTML. 

<?php
// Sample JSON data
$json_data = '{"name": "<script>alert(\'XSS attack\')</script>"}';

// Decode the JSON data
$data = json_decode($json_data, true);

// Output the escaped data with CSS class
echo '<div class="name">' . htmlspecialchars($data['name']) . '</div>';
?>
