javascript - How can I use CSS @media for responsive with makeStyles on Reactjs Material UI?

Question

const useStyles = makeStyles(theme => ({
  wrapper: {
    width: "300px"
  },
  text: {
    width: "100%"
  },
  button: {
    width: "100%",
    marginTop: theme.spacing(1)
  },
  select: {
    width: "100%",
    marginTop: theme.spacing(1)
  }
}));

Is there a way to use CSS @media at the above variable?

if impossible, how can I make my custom css for responsive?

Below is an example showing two ways of specifying media queries within makeStyles (further down is a v5 example using styled). You can use up, down, only, and between functions in theme.breakpoints (which generate the media query strings for you based on the breakpoints specified in the theme), or you can use media queries directly.

import React from "react";
import Button from "@material-ui/core/Button";
import { makeStyles } from "@material-ui/core/styles";

const useStyles = makeStyles(theme => ({
  button: {
    color: "white",
    [theme.breakpoints.down("xs")]: {
      marginTop: theme.spacing(1),
      backgroundColor: "purple"
    },
    [theme.breakpoints.between("sm", "md")]: {
      marginTop: theme.spacing(3),
      backgroundColor: "blue"
    },
    "@media (min-width: 1280px)": {
      marginTop: theme.spacing(5),
      backgroundColor: "red"
    }
  }
}));
export default function App() {
  const classes = useStyles();
  return (
    <Button className={classes.button} variant="contained">
      Hello World!
    </Button>
  );
}

Below is a similar example using v5 of Material-UI. This has been adjusted to use styled instead of makeStyles and the usage of theme.breakpoints.down and theme.breakpoints.between has been adjusted based on the changes in behavior for those functions (down is now exclusive of the specified breakpoint rather than inclusive and the end breakpoint for between is also now exclusive, so for both of those the breakpoint specified needs to be one up from what would have been used in v4). Also, the min-width of the media-query that is specified directly has been adjusted from 1280px to 1200px to match the new value of the lg breakpoint in v5.

import React from "react";
import Button from "@material-ui/core/Button";
import { styled } from "@material-ui/core/styles";

const StyledButton = styled(Button)(({ theme }) => ({
  color: "white",
  [theme.breakpoints.down("sm")]: {
    marginTop: theme.spacing(1),
    backgroundColor: "purple"
  },
  [theme.breakpoints.between("sm", "lg")]: {
    marginTop: theme.spacing(3),
    backgroundColor: "blue"
  },
  "@media (min-width: 1200px)": {
    marginTop: theme.spacing(5),
    backgroundColor: "red"
  }
}));
export default function App() {
  return <StyledButton variant="contained">Hello World!</StyledButton>;
}
