How was style introduced？

[Angry-Sparrow]

Recently, I am reading the source code of rsuite and trying to build a similar component library by myself.
However, I am very confused about how to introduce the style of components?
I couldn't find the operation in the code.

I would be very grateful if someone knows and gives me a reply.

RSuite does not import styles into the components themselves. Styles are packed within the npm package and users import the styles in their projects. Guide

I understand. Thank you very much. But I don't understand why. It seems unfriendly.

Because RSuite is using a preprocessor-based style implementation currently. But we may move to a css-in-js approach in future if we find it bringing considerable advantage. Stay tuned!
