With styled-jsx plugins
Next.js ships with styled-jsx allowing you to write scope styled components with full css support. This is important for the modularity and code size of your bundles and also for the learning curve of the framework. If you know css you can write styled-jsx right away.
This example shows how to configure styled-jsx to use external plugins to modify the output. Using this you can use PostCSS, SASS (SCSS), LESS, or any other pre-processor with styled-jsx. You can define plugins in .babelrc. In this case PostCSS was used as an example. PostCSS plugins are defined in package.json.
More details about how plugins work can be found in the styled-jsx readme
