Hmmm
That code works for me anywhere I put it, except for the background image which I dont have.
I get a blue page with scrolling text.
As the css is all in the file there is no reason why it shoudl not work anywhere.
What browser are you using, try all the obvious ones like IE, FF, Chrome, Edge(if you are W10)
