What is the difference between using HTML and PHP for client-side actions like creating a marquee effect?

Using HTML alone for client-side actions like creating a marquee effect is limited because HTML is a static language and cannot handle dynamic content or interactions. PHP, on the other hand, is a server-side scripting language that can generate dynamic content based on user input or other factors. By using PHP along with HTML, you can create more interactive and dynamic web pages.

<?php
// PHP code to create a marquee effect using a loop
$marqueeText = "This is a sample marquee text. ";
$marqueeSpeed = 3; // speed of marquee in seconds

echo '<marquee behavior="scroll" direction="left" scrollamount="3">' . $marqueeText . '</marquee>';
?>
