How to handle custom general purpose styles?

## 💬 Question

What is the best/recomended way to handle general purpose styles for components like **space between form inputs** or **headings** spacings etc. Create a general file called `spacing` and put all general styles here about spacing and import it and applied it in every component where should be needed, or create something inside `mapping.json`?
