Material design is very opinionated on how design elements should behave and look. The basics of which revolve around certain visual elements (physics, space, momentum and light) which are used to create specific UX elements.
This is very helpful because it creates a consistent feel without making every design look the same. This can be seen in Materialize too, where each element may be customized but still it keeps the consistent look of the material design.
Simple animations without too much fanciness keep the performance high and size small.
