+## How to customize the default styles of a component
 
 When overriding default styles we recommend using `!important` variants of [`Tailwindcss`](https://tailwindcss.com/docs/installation) util-classes. Preferably version 3 or later (or a version earlier than version 3 that supports JIT compiling) so that just-in-time compilation can be utilized to generate `!important` variants of a tailwind class on the fly that can then be used to override the default styles of a lite-react-ui component.
