How can the confusion between class attributes and div classes be avoided when including PHP files for styling elements?

To avoid confusion between class attributes and div classes when including PHP files for styling elements, it is important to use unique and descriptive names for both. One common approach is to prefix all class attributes with a specific identifier, such as "attr-" or "data-". This helps differentiate between the two types of classes and prevents any conflicts or misunderstandings.

<?php
// Include PHP file for styling elements
include 'styles.php';
?>

<div class="attr-customClass">
    <p class="data-customStyle">This is a styled paragraph.</p>
</div>
