A quick glance at the code you posted indicates that some sort of container is required.
It does not specify how large or small it needs to be. If you are trying to fill a whole page just don’t set a width on the div (or whatever) is going to be your container.
Or if you do want a width…use a % to make it fluid.
I’m unfamilar enough with JS to ascertain whether it should have an ID of container or just a class.
