Hi @bedribulut

I’m not knowledgable enough about the topic, but have you read @horusofoz’s longer explanation in this forum?

Help needed with Introducing a complete toolchain

I think I finally found the fix. tldr: Follow the instructions as provided but before running the transformation with npx parcel src/index.html, add "postcss-preset-env": "^6.7.0", to package.json. Long version I repeated the steps in the instructions of Introducing a complete a toolchain too many times to count. I worried I must be making an error in copying somewhere but even copy/pasting commands and file content repeated the same errors. I posted here and to Stackoverflow seeking guidance…

Maybe this shines a bit of light on it.
