What are some common pitfalls when trying to pass PHP variables to CSS modals?

One common pitfall when trying to pass PHP variables to CSS modals is not properly echoing the PHP variable within the CSS code. To solve this issue, you can echo the PHP variable within a style attribute or use inline PHP code within the CSS file.

<?php
// PHP variable to be passed to CSS modal
$modalColor = "red";
?>

<div class="modal" style="background-color: <?php echo $modalColor; ?>">
  <p>This is a modal with a dynamic background color.</p>
</div>
