      float: left;
    }

    ${Item}:hover {
      text-decoration: underline white;
      cursor: pointer;
    }
  }
`;

Configuration

.babelrc

{
    "plugins": [
      "styled-components-mqpacker"
    ]
}

This plugin uses postcss and css-mqpacker to extract media queries from styled components and puts them into the injectGlobal block. If injectGlobal is not used it will be created.
