errors in the animations code are of type `any` but are consistently
used as if there were `string`s, change `any` to `string` to make
typing more accurate

the final styles created in buildStyles lack normalization, meaning that pixel values remain as numbers (without "px") and so such properties fail to be correctly set/applied
Example: "width: 300" is applies as "width": "300" (and thus ignored) instead of the correct "width": "300px"
