Rewind-UI uses only TailwindCSS classes, which can be overridden using the className prop on each component or can be fully customized using a theme provider.

It is built on top of the CVA (class-variance-authority - https://cva.style/docs) library, so if anyone needs to adjust the theme, will just need to edit the CVA files.

Furthermore it must be noted that you can add either all the style files in your tailwind.config.js file, or only those that you are going to use, so that you can avoid having a bloated css file.

Even though it is still in beta I would love to hear your feedback on it.
