We know that React handles the user interfaces of around 10 million websites across the globe. No doubt, the base library of React is robust, so there are multiple component libraries like MUI, Antdesign, Rebass, ThemeUI, and more which provide valuable design elements. Rebass is the simple UI component library of React which is highly composable and built with styled-components to keep styles isolated. Many react js developers use React Rebass over [Theme UI](https://theme-ui.com). Because Rebass components are reusable primitive components, they are ready to go out with the box with the best default styles. Moreover, all the rebass components are basically Box components that consist of a style system to give you the ability to style through props.

Although React Rebass is a functional UI component library that uses Props during the app development. And theming is used to provide layout styles, typographic styles, colors, and component variants. Even the agencies hire React js developer to customize the theming with the help of a theme provider. So, in this blog, we will discuss Rebass and its features. Also, why do React js developers use Rebass over Theme UI?

With Rebass, you can get started with your design system without having to write a lot of boilerplate code. Emotion, Styled Components, and Styled System are used to create Rebass, a themeable primitive UI component library for React. Because it is designed with Styled System, any Styled System theme object should work with Rebass. Rebass components include a standardized style props API to create larger component libraries.

No, doubt Rebass has a versatile variations API and is totally themeable. It is designed to be used as a foundation for building custom component librarie,s and design systems. In fact, Rebass is also a prominent tool for creating prototypes and user interfaces without investing time in creating a custom design system upfront. Rebass components are used independently or in conjunction with apps created using Theme UI. Hence, you can avail of React js development services to use React rebass in your app design.

##What are the steps to give theming to the Rebass Components?

To provide a theme to the rebass components, the professionals will require to add a theme provider. With it, you can completely customize the theme of the Rebass components.

> - Firstly, create a React application with the help of the following command:

__`npx create-react-app foldername`__
> - After it, you will be required to create your project folder by using the below command./

__`cd foldername`__
> - Now, Install React Rebass and form the components in the directory.

__`npm i rebass`__
> - Further, to apply the theme to the Rebass components, you will need to add a ThemeProvider component to the root of the app and pass the theme object as a prop. Even if you are using Emotion, you need to install the emotion-theming package.
> - If you use Rebass with the Theme UI,  you will need to use its __ThemeProvider__ or the __`gatsby-plugin-theme-ui`__ package.
 

```react
import React from 'react'
import theme from './theme'
import { ThemeProvider } from 'emotion-theming'
// or for use with Theme UI:
// import { ThemeProvider } from 'theme-ui'
 
export default props =>
<ThemeProvider theme={theme}>
{props.children}
</ThemeProvider>
```
However, Rebass follows the theme Specifications to allow the professionals to define the thematic values in a more portable format. Moreover, you will not require additional configuration because Rebass will work with Styled System or Theme UI. Therefore, it means that all themes are created to use with the Rebass and can work with other applications that follow the same specification.
