Is v3 compatible with tailwindcss v2? Have you tried upgrading tailwindcss to v3 too?

[mariemattick1999]

Yes, I tried that to, but it didn't change anything

I think this is because you are using an old config (v2) which is not compatible with v3 in which the closures evaluation has changed:

v2:

module.exports = {
  theme: {
    backdropBlur: (theme) => theme('blur'),
  }
}

v3:

module.exports = {
  theme: {
    backdropBlur: ({ theme }) => theme('blur'),
  }
}
