So I'm basicly pretty much a noob as it comes to HTML and other coding. What I'm recently trying is to make a pop-up cover over a certain website someone is on.
Lets say they're at this website called www.robsurd.com
When they go to my website a sorta pop-up replaces the www.robsurd.com website.
I know it's possible since I've done it before but I lost all my coding files.
Could use some help here
