Remove Material UI icon margin

问题

Does anyone know how to remove the margin from material UI icons!? I want for mobile to remove that margin, which is margin-left: -4px and margin-right: 8px ? Is there anyway to override it with classes? The code below is not working:

personIcon: {
    color: theme.palette.primary.main,
    fontSize: "27px !important",
    [theme.breakpoints.down("xs")]: {
      margin: "0px !important",
    },
  },

In addition I want to override it only for the current component. ;]

You need to target the startIcon customization point, as documented here.

In my example I just used SvgIcon so I don't have to fiddle around with looking for the icons module. You can import Person from @material-ui/icons/person

const { Button, makeStyles, SvgIcon, createMuiTheme } = MaterialUI;

const theme = createMuiTheme();
const useStyles = makeStyles((theme) => ({
  icon: {
    '&& > svg': {
      fontSize: 27,
    },
    [theme.breakpoints.down('xs')]: {
      margin: 0,
    },
  },
}));

const NoMargin = () => {
  const classes = useStyles();

  return (
    <Button
      classes={{ startIcon: classes.icon }}
      startIcon={
        <SvgIcon>
          <path d="M12 12c2.21 0 4-1.79 4-4s-1.79-4-4-4-4 1.79-4 4 1.79 4 4 4zm0 2c-2.67 0-8 1.34-8 4v2h16v-2c0-2.66-5.33-4-8-4z" />
        </SvgIcon>
      }
    >
      click me
    </Button>
  );
};

ReactDOM.render(<NoMargin />, document.getElementById('root'))

Try this :

personIcon: {
    color: theme.palette.primary.main,
    fontSize: "27px !important",
    [theme.breakpoints.down("xs")]: {
      "& > *": {
         margin: 0,
       },
    },
},
