Hi, could you post your Tailwind config?

[martijndewit]

It's kind of big, so I removed the color and font declaration. tailwind.config.ts:

import type { Config } from 'tailwindcss'
import defaultTheme from 'tailwindcss/defaultTheme'
import colors from 'tailwindcss/colors'
import fluid, { extract, screens } from 'fluid-tailwind'
import typography from '@tailwindcss/typography'
import forms from '@tailwindcss/forms'
import containerQueries from '@tailwindcss/container-queries'

export default <Partial<Config>>(<unknown>{

  content: {
    extract,
  },

    clear: false,
    space: false,

Thanks, are you using @nuxtjs/tailwindcss too?

Hi, I also get the same error in both 3.14.0 and the current latest 3.14.159. And yes, I'm also using @nuxt/tailwindcss via nuxt/ui

[barvian]

Hi, I just pushed fluid-tailwind@1.0.4 which should fix this. Please comment if you're still experiencing issues 👍

[martijndewit]

Seems to be resolved! Thank you!
