I got a problem. I'm new to $ and i want to make a div to be displayed 3 seconds after the page loaded but i want it displayed on the desktop( behind the webpage).

I made the part where the div slides from the right-bottom corner but i can't make it slide behind the browser page.So if you minimize the webpage stil slides but it slides on your desktop.

Can someone help me and explain ( link or own words) what it takes and what i need to learn.
