Scrollable image over static image

Alright, I’ve got a doozy for you all today. I have a long image in a scrollable div box, but it’s a web page image, so what I’d love is to place that scrollable image over a laptop mockup so it looks like you’re scrolling the web page on the laptop screen. Not only am I not sure how to do that (setting the mockup as background? As an image at -1 index?), but how to ensure that the positioning stays consistent responsively. Any thoughts would be immensely appreciated!

Is this what you’re looking for?

Hi Jacie,
I’m not sure why, but I never got a notification when you responded, so I apologize for the delay and really appreciate it, because this is exactly what I’m looking for. Thanks again!
