I like how you got a disclaimer for iframe failure, it is pretty neat

thanks! a good 3/4 of my pages are meant to be displayed inside the iframe on my index page and with Neocities displaying (i'm too lazy to delete the update posts) and Google indexing some of them (trying to remove those pages from search results with Search Console), I had to add this. The code behind it is a snippet that I found on geeksforgeeks.org and modified a bit, i'm trying to learn a bit of javascript lol
