I'm working on refactoring some sites in ECSS right now. I can report back when done if you care enough! As of now, you can look into the ecss.info CSS on github if you want a taste. Not large-ish, but still representative I'd say. https://github.com/efficientcss/ecss.info https://github.com/efficientcss/ecss.info As for the "just-in-time" CSS, I include the link tag directly in the component itself. Could be Web component or any other type. Yes, the link tag is repeated, but the browser does not download/interpret the file again since it's cached. Been experimenting with this in the past year and I only see advantages. First, there's a lot less unused CSS in any page (for instance, on Tailwind's front page there is something like 80% unused CSS as per Google coverage tool). Second, you have a live link to the CSS in your component file (I use Vim but I know VS Code can follow sources too).
