I'm using this code on my wiki to add a snow effect however I just noticed that it doesn't cover the whole background anymore, probably because it's a bit old. Can someone tell me how to fix it?

I also suggested to make a dev version of this since to make it easier to add it for everybody, especially during the holidays. Maybe if someone is familiar with the dev wiki can do it.
