Classname overrides

To avoid completely overwriting the default styles, the className prop can be used to override the default classes. Rewind-UI is using tailwind-merge to merge the default classes with the classes you provide in the className prop and resolve any possible conflicts.

    className="border border-2 border-dashed border-purple-700"
