function addSkin(checked) {
  const html = document.getElementsByTagName('html')[0];
  html.dataset.theme = checked ? 'dark' : 'light';
  html.className = checked ? 'dark' : '';
}

      {
        test:/\.css$/,
        use: [{ loader: MiniCssExtractPlugin.loader,},
          { loader: "css-loader", options: { modules:true }},
          { loader: "postcss-loader"}
        ]
      },

 ConfigProvider.config({
    theme: {
      bodyBackground: 'rgb(20,20,20)',
      primaryColor: '#25b864', // 全局主色
    },
  });

import styled from 'styled-components'
 
const Title = styled.h1`
    font-size: 1.5em;
    text-align: center;
    color: palevioletred;
`;
// 相当于  const Title = styled.h1(xx)
const Wrapper = styled.section`
    padding: 4em;
    background: papayawhip;
`;
    render () {
        return (
            <Wrapper>
                <Title>Hello styled-components</Title>
            </Wrapper>
        )
    }

.override-ant-btn {
