Ask HN: What is your CSS setup in 2017?

PostCSS + sometimes a lightweight helper library such as http://basscss.com/ which provides some really nice defaults.

I like how the Rails Asset Pipeline gives you a single CSS artifact with a cache-busting hash in the name, but I've been trying to use Webpack for some new projects and I was surprised to learn that by default it doesn't create any CSS file, but embeds the CSS in Javascript and injects it at runtime. Is that considered better nowadays? What are the pros and cons? I Googled around a bit but didn't find any answers.

Btw here is a sample webpack config that uses ExtractTextPlugin to get behavior more like the Asset Pipeline, including pulling in Bootstrap and getting correct font references. Maybe someone can use it:
