I use TailwindCSS with my epub project to style the book. However, stuff that are usually legal that Tailwind produces, don't pass the epub checker's validator. I assume that the parser doesn't fully conform to the CSS standard, or there are some limitations in the EPUB standard that I'm missing.
This seems to be an issue with the underlaying epubcheck EPUB validator. Please open an issue with them in their repo: https://github.com/w3c/epubcheck
