How can the use of HTML5 and CSS in PHP code improve the presentation and styling of output data?

By using HTML5 and CSS in PHP code, we can improve the presentation and styling of output data by separating the content from the design. This allows for a more organized and maintainable codebase, making it easier to update the styling without affecting the underlying logic. Additionally, HTML5 and CSS provide a wide range of styling options and responsive design features that can enhance the user experience.

<?php
// PHP code to output data with HTML5 and CSS styling

$data = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";

echo "<!DOCTYPE html>";
echo "<html>";
echo "<head>";
echo "<style>";
echo "body { font-family: Arial, sans-serif; background-color: #f0f0f0; }";
echo ".content { max-width: 800px; margin: 0 auto; padding: 20px; background-color: #fff; border-radius: 5px; box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1); }";
echo "</style>";
echo "</head>";
echo "<body>";
echo "<div class='content'>";
echo "<p>$data</p>";
echo "</div>";
echo "</body>";
echo "</html>";
?>
