Unfortunately it's not accurate. It could approach a better accuracy with essentially a large css file that has a prebaked "simulation" that plays, but it's best to use JS for this type of thing. It's simple to make in JS, and it can be intractable and allow for changing the inital conditions of the simulation, rather than an animation of a simulation.
