使用React-JSS中的父伪类修改子类

import React from 'react';
import { createUseStyles } from 'react-jss';

const useStyles = createUseStyles({
  parent: {
    '&:hover': {
      // 父伪类:hover，当鼠标悬停在父元素上时应用的样式
      backgroundColor: 'red',
    },
  },
  child: {
    color: 'blue',
  },
});

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

  return (
    <div className={classes.parent}>
      <span className={classes.child}>我是子元素</span>
    </div>
  );
};

export default MyComponent;
