What are some best practices for integrating PHP, HTML, and CSS to create a responsive design for displaying temperature data on different devices?

To create a responsive design for displaying temperature data on different devices, you can use PHP to dynamically generate the data, HTML for structuring the content, and CSS for styling and making it responsive. One best practice is to use media queries in your CSS to adjust the layout based on the screen size of the device.

<?php
$temperature = 25; // Example temperature data

echo "<div class='temperature'>$temperature°C</div>";
?>
