React is a wonderful tool to write reusable UI components but it takes no decisions on how styles should be written. This leads to a huge amount of different approaches, most of them based on CSS in JS, that usually introduce some coupling with your code making crucial the decision of choosing one of them. Is it possible to skip writing the styles so that a component doesn't depend on them anymore? Can we build complex components in a way that allows them to be reused even for React Native? This talk will show how this is achievable with the upcoming React Toolbox Core.
