How to Change Root Background Color with Material-UI Theme in ReactJS

Introduction

ReactJS is a popular JavaScript library for building user interfaces, and Material-UI is a set of React components that implement Google's Material Design. One of the features of Material-UI is the ability to customize the theme of your application, including the background color of the root element. In this article, we'll go over how to change the root background color with Material-UI theme in ReactJS.

Steps

Step 1: Create a Theme

The first step is to create a theme for your application. You can do this by using the createMuiTheme function from Material-UI. Here's an example:

{`import { createMuiTheme } from '@material-ui/core/styles';

const theme = createMuiTheme({
  palette: {
    background: {
      default: '#f5f5f5'
    }
  }
});

export default theme;`}

This code creates a theme with a default background color of #f5f5f5.

Step 2: Provide the Theme to your Application

The next step is to provide the theme to your application. You can do this by wrapping your application with the ThemeProvider component from Material-UI. Here's an example:

{`import React from 'react';
import { ThemeProvider } from '@material-ui/core/styles';
import theme from './theme';

function App() {
  return (
    
      // Your application code here
    
  );
}

export default App;`}

This code wraps the application with the ThemeProvider component and provides the theme we created in the previous step.

Step 3: Change the Root Background Color

Finally, we can change the background color of the root element by using the makeStyles hook from Material-UI. Here's an example:

{`import React from 'react';
import { makeStyles } from '@material-ui/core/styles';

const useStyles = makeStyles((theme) => ({
  root: {
    backgroundColor: theme.palette.background.default,
    // Other styles here
  },
}));

function MyComponent() {
  const classes = useStyles();

  return (
    

      // Your component code here
    
  );
}

export default MyComponent;`}

This code uses the makeStyles hook to create a style object with a backgroundColor property that's set to the default background color from our theme. We can then apply this style object to the root element of our component using the className attribute.

In this article, we went over how to change the root background color with Material-UI theme in ReactJS. By following these steps, you can easily customize the theme of your application to match your brand or design requirements.
