Hey there! I'm as surprised as you to see this as being marked as unrecognized because it does work in browsers 😅

Do you have some info on how to reproduce this? I've tried to run it inside a Vite playground (using the @tailwindcss/vite package) with both postcss and lightningcss as the configured preprocessor and I never saw this warning (neither in dev mode nor in production).

Would be cool if we can track down where the parsing goes wrong and send a fix upstream.

I'm also seeing this error in a nuxt 3 project. My versions are:

nuxt: 3.14.1592,
tailwindcss: 4.0.0-beta.7
@tailwindcss/vite: 4.0.0-beta.7
vite: 5.4.11

@benfeather are u using nuxt/ui v3?

[benfeather]

@simonmaass No, i'm not using any UI library.

I think it was a problem with the vite css processor, the problem was solved when I switched from postcss to lightningcss

Has anyone solved this issue?
