Hi there! If you've ever built a React app and found it difficult to make your layout look good on both desktop and mobile, you're not alone. Good news? Material UI (aka MUI) makes it easy to create responsive design with its powerful Grid system. Let’s see how you can create a completely responsive layout using MUI Grid, step by step, with code you can copy and customize.

Why Use Material UI Grid?

MUI's Grid is based on top of CSS Flexbox, and it works on a 12-column layout system. It means you can divide your layout into sections without much stress, and control different section's behaviour on different screen sizes. Now you don't have to write separate CSS media queries all over the place.

Quick Setup

If you’re new:

npx create-react-app mui-grid-demo
cd mui-grid-demo
npm install @mui/material @emotion/react @emotion/styled

Done? Now, you can move ahead. Open up your App.js or any component, and let’s go.

Basic Grid Layout

Check out this simple responsive layout with 3 boxes:

import React from "react";
import { Grid, Box } from "@mui/material";

const ResponsiveGrid = () => {
  return (
    <Grid container spacing={2}>
      <Grid item xs={12} sm={6} md={4}>
        <Box p={2} bgcolor="primary.main" color="white">Box 1</Box>
      </Grid>
      <Grid item xs={12} sm={6} md={4}>
        <Box p={2} bgcolor="secondary.main" color="white">Box 2</Box>
      </Grid>
      <Grid item xs={12} sm={12} md={4}>
        <Box p={2} bgcolor="error.main" color="white">Box 3</Box>
      </Grid>
    </Grid>
  );
};

export default ResponsiveGrid;

What's happening here?

• xs={12}: Full width on extra-small screens (mobile)

• sm={6}: Half width on small screens (like tablets)

• md={4}: One-third width on medium screens and up (desktops)

Boom! Here you built a layout that adapts to screen sizes.

Nested Grids

You can even nest grids inside other grids:

<Grid item xs={12}>
  <Grid container spacing={1}>
    <Grid item xs={6}>Nested Grid 1</Grid>
    <Grid item xs={6}>Nested Grid 2</Grid>
  </Grid>
</Grid>

Useful when you have to break things down within a section.

Styling with Box

MUI’s Box component is the best thing for you. You can quick style by adding padding, colors, margins, borders, all using the sx prop or shorthand props like p, m, bgcolor, etc.

<Box p={2} bgcolor="info.main" color="white" borderRadius={2}>
  Styled Box
</Box>

Want More Control?

Try it:

• alignItems, justifyContent on Grid container

• display="flex" in Box for layout adjustments.

• hidden component to hide/show stuff based on screen size

Conclusion

Now you dont have to write a single media query to create a responsive UI, MUI’s Grid system makes it possible. The result is clean, predictable, and works great. Next time you’re building a dashboard, landing page, or product listing, no need to stress out use Grid.

Frequently Asked

Q. How does the MUI Grid system work in React?

A. The MUI Grid system is based on a 12-column layout using CSS Flexbox. You can control how components adjust across the grid at different screen sizes by assigning column widths to components with props like xs, sm, md, etc.,. With this you can create responsive designs without writing custom media queries.​

Q. How do I make a responsive layout using MUI Grid?

A. To create a responsive layout with MUI Grid, wrap your components in a Grid container and specify the column span for each item at various breakpoints. For example:​

<Grid container spacing={2}>
  <Grid item xs={12} sm={6} md={4}>
    {/* Content */}
  </Grid>
</Grid>

In this setup, the grid item spans full width on extra-small screens, half width on small screens, and one-third width on medium and larger screens.​

Q. Can I nest Grids inside other Grids in MUI?

A. Yes, you can place a Grid container inside a Grid item to create complex layouts. This approach is useful for structuring components hierarchically and managing spacing effectively.​
