WHERE
ID = :P44_USER_ID;
/* After showing this print message */
HTP.P('<div class="t18notification"><font size="3" color="BLUE">
Your Account registered Sucessfully...!
</font></div>');
/* This message must show after 3 seconds after the above print message */
HTP.P('<script type="text/javascript">

A COMPLETE page is generated. With ALL content. Then that is shipped of by the web server to the web browser. So putting a delay between 2 HTP.put() statements only slows down the generation of that HTML page - before the ENTIRE page is shipped off to the web browser.
Web browsers are block devices - not typewriter devices.
If you want delays between content rendering on the web browser, you need to use Javascript (executes inside the browser).
If you want to make a web browser act like a typewriter devices, then you need to look at using Ajax calls from Javascript to the web server.
It is important that you fully grasp web-based client-server, when developing web applications - understanding how the HTTP protocol looks and works, and understanding the interaction between client and server works.
