Alan What?
[annoy my right-angled speediness]
What is space-time? What is it made of? How and why does gravity affect it? Where does space-time come from? Where does gravity come from?

The kid in my avatar is thinking those very questions. They're tough ones. Its just so fun to wonder!

They are dimensions consisting of arrangements of atomic elements in quantum form, matter, EM wave energies and subatomic particles.

Space-time is a mathematical model used in the explanation of a relativistic universe. I don’t think it’s “made of” anything. It’s more like a system of rules/properties that everything of substance exists within the framework of. Think of space-time as a four-dimensional plane or graph, and matter as data points on that plane.
I think

Fox Paws is pretty close. I guess technically everything is some kind of abstraction of some rules that are used to explain the behaviour of certain phenomena in the universe. We use the term "space-time" in the same sense. It's no less a thing than any other material or substance, in that sense. It's just a different level of abstraction.
More to the point, we don't really have a good explanation for space-time i.e. on a quantum level, we haven't discovered a reason for why things act the way they do on the classical scale that would explain relativistic effects or gravity. It's possible our basic metriculation of physics is fundamentally flawed.
