Hi everyone!

I’m currently using Tailwindcss 3.x with Jekyll(+jekyll-postcss gem). Has anyone here upgraded to Tailwindcss 4.0?

If so, I’d appreciate it if you could share your story.

I just upgraded my template project to Tailwind v4, you can see the [diff here on GitHub](https://github.com/chrisgrande/jekyll-with-tailwind/commit/4c06d20e3c9857367dc1ab4b9dde58fc2eb03bab). I use the jekyll-postcss-v2 gem. Besides the technical, there are a few [renamed](https://tailwindcss.com/docs/upgrade-guide#renamed-utilities) and removed utilities, i.e. `shadow-sm` → `shadow-xs`, etc…

Thanks! That’s really helpful.

> I switched to jekyll-postcss-v2 and it easily solved the issues I had with upgrading. Also, it looks like using tailwindcss4 with jekyll-postcss-v2 is a good combination.
