React MUI is a UI library that provides fully-loaded components, bringing our own design system to our production-ready components. MUI is a user interface library that provides predefined and customizable React components for faster and easy web development, these Material-UI components are based on top of Material Design by Google.
React MUI How To Customize is the process of modifying the default styles and behavior of components in the Material-UI library to fit the specific needs of a project or application. This customization can include changes to colors, typography, layout, and other design elements to match the look and feel of the project.
How To Customize Content:
- One-off Customization: It refers to making small changes to the default styling of a specific component in a single instance, rather than creating a global theme or customizing all instances of a particular component. This can be done by using the ‘sx’ prop, Overriding styles with class names, or with State classes.
- Reusable Component: It refers to a component that can be used in multiple places throughout an application, rather than being specific to a single location or page. These components can be customized using the ‘styled’ function that overrides the default styles for a specific component.
- Global theme overrides: It refers to the process of customizing the default styling of all components in an application by creating a global theme. This can be done by using the ‘createTheme’ function to create a new theme object that overrides the default values for various styling options, such as colors, typography, and spacing. Once a theme is created, it can be passed to the ‘ThemeProvider’ component,
- Global CSS override: It refers to the process of customizing the default styling of all components in an application by applying global CSS styles. This can be done by importing a CSS file containing custom styles into the root of the application, or by using the ‘GlobalStyles’ component to create a global style component that can be used to apply styles to specific elements or classes throughout the application.
Creating React Project:
Step 1: Create React app by writing the below code in any command line.
npx create-react-app app_name
Step 2: Then, we have to move into the folder we will be working on.
cd project_name
Step 3: We will be installing the @mui/material library for working on our project.
npm install @mui/material @emotion/react npm install @emotion/styled @mui/icons-material
Project Structure:
Folder Structure
Steps to run the application: Write the below code in the terminal to run the server:
npm start
Example 1: Below is the code for styling a Box component using the ‘sx’ prop.
- App.js
Javascript
import styled from "@emotion/styled"; import { Box } from '@mui/material';   const Text = styled.div`     padding-left: 10px;     padding-right: 5px; `;   const Logo =   const SimpleExample = () => {     return (         <Box sx={{             width: '200px', height: '400px', boxShadow: 2,             margin: '10px', bgcolor: '#9dedb2'        }}>             <img src={Logo} alt='GFG logo' width='200px'                height='200px' />             <Text>A Computer Science portal for neveropen.                 It contains well written, well thought and                 well explained computer science and programming                 articles.             </Text>         </Box>     ); }   export default SimpleExample; |
Output:
Simple example using ‘sx’ prop
Example 2: Below is the code for making a Reusable Slider component using Global CSS override.
- App.js
Javascript
import * as React from 'react'; import { Slider, Box } from '@mui/material'; import { alpha, styled } from '@mui/material/styles'; import GlobalStyles from '@mui/material/GlobalStyles';   const SuccessSlider = styled(Slider)(({ theme }) => ({     width: 250,     color: theme.palette.error.main,     '& .MuiSlider-thumb': {import * as React from 'react'; import { Slider, Box } from '@mui/material'; import { alpha, styled } from '@mui/material/styles'; import GlobalStyles from '@mui/material/GlobalStyles';   const SuccessSlider = styled(Slider)(({ theme }) => ({     width: 250,     color: theme.palette.error.main,     '& .MuiSlider-thumb': {         '&:hover, &.Mui-focusVisible': {             boxShadow: `0px 0px 0px 8px ${alpha(theme.palette.error.main, 0.16)}`,         },         '&.Mui-active': {             boxShadow: `0px 0px 0px 14px ${alpha(theme.palette.success.main, 0.16)}`,             color: theme.palette.success.main         },     }, }));   const Example = () => {     return (         <Box sx={{             boxShadow: 2,             margin: '50px',             width: '350px',             textAlign: 'center'        }}>             <GlobalStyles styles={{ h1: { color: 'purple' } }} />             <h1>This is a Slider</h1>             <SuccessSlider defaultValue={30}                 valueLabelDisplay='on'                sx={{ margin: '20px' }} />         </Box>     ) }   export default Example;         '&:hover, &.Mui-focusVisible': {             boxShadow: `0px 0px 0px 8px ${alpha(theme.palette.error.main, 0.16)}`,         },         '&.Mui-active': {             boxShadow: `0px 0px 0px 14px ${alpha(theme.palette.success.main, 0.16)}`,             color: theme.palette.success.main         },     }, }));   const Example = () => {     return (         <Box sx={{ boxShadow: 2,                    margin: '50px',                    width: '350px',                    textAlign: 'center' }}>             <GlobalStyles styles={{ h1: { color: 'purple' } }} />             <h1>This is a Slider</h1>             <SuccessSlider defaultValue={30}                            valueLabelDisplay='on'                            sx={{ margin: '20px' }} />         </Box>     ) }   export default Example; |
