Codecademy nested browser window


So, I’m working on a website that’d be a trillion times better if it had a nested browser window like in some of the codecademy lessons, but i’ve never seen anyone do anything like that before, and online I can’t find anything either, but I’m willing to put in as much work in as i can, I was just wondering what it is, and how a wee little web developer like me could code one of his own, thanks for the help


I think it’s just some interesting wizardry with some <div>s and an iframe, rather than specifically embedding an actual browser.
