How can one troubleshoot issues with CSS not being interpreted in PHP-generated HTML?

Issue: If CSS is not being interpreted in PHP-generated HTML, it may be due to incorrect file paths in the CSS link or the CSS file not being properly linked. To solve this issue, ensure that the CSS file path is correct and that the CSS file is properly linked in the PHP-generated HTML.

<!DOCTYPE html>
<html>
<head>
    <title>PHP-Generated HTML with CSS</title>
    <link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>

<?php
// PHP code to generate HTML content
echo "<div class='content'>PHP-generated content with CSS styling</div>";
?>

</body>
</html>
