Container

The container centers your content horizontally. It's the most basic layout element.

While containers can be nested, most layouts do not require a nested container.

Fluid

A fluid container width is bounded by the maxWidth prop value.

import * as React from 'react';
import CssBaseline from '@mui/material/CssBaseline';
import Box from '@mui/material/Box';
import Container from '@mui/material/Container';

export default function SimpleContainer() {
  return (
    <React.Fragment>
      <CssBaseline />
      <Container maxWidth="sm">
        <Box sx={{ bgcolor: '#cfe8fc', height: '100vh' }} />
      </Container>
    </React.Fragment>
  );
}

<Container maxWidth="sm">

Fixed

If you prefer to design for a fixed set of sizes instead of trying to accommodate a fully fluid viewport, you can set the fixed prop. The max-width matches the min-width of the current breakpoint.

import * as React from 'react';
import CssBaseline from '@mui/material/CssBaseline';
import Box from '@mui/material/Box';
import Container from '@mui/material/Container';

export default function FixedContainer() {
  return (
    <React.Fragment>
      <CssBaseline />
      <Container fixed>
        <Box sx={{ bgcolor: '#cfe8fc', height: '100vh' }} />
      </Container>
    </React.Fragment>
  );
}

<Container fixed>
