I mean, I'd imagine it's trivial to do without js. Just try to load an image or similar with a name that'd be blocked into the background image for a div that covers the entire page. Should silently fail to load with a blocker, or shows your error image if they don't.
As a total HTML/CSS noob, I'll definitely have to look up how to do this. I'll probably end up trying it on the other site just in case I royally mess up my main site by accident. I at least have immediate backups for the other site right now, so I don't mind experimenting with it.
