# Customization Strategies

There is two main way to create your Keycloak theme.  

## CSS Level Customization

This is the recomended approach as it is easy to implement and easy to maintain. Even non web developer should be able to pull it off.  

In this approach you'll use your favorite styling solution it can be:

* Plain CSS
* [Tailwind](https://tailwindcss.com/docs/reusing-styles#extracting-classes-with-apply)
* A language superset of CSS lile [Sass](https://sass-lang.com/) or [Less](https://lesscss.org/)
* An utility class based CSS framework like [Bootstrap](https://getbootstrap.com/) or [Fundation](https://get.foundation/)

## React Component Level Customization

If you want to use your React component library like [Shadecn/UI](https://ui.shadcn.com/), [MUI](https://mui.com/) or [Ant](https://ant.design/) you have to go down at the component level.
