This gist may be your full solution or just the starting point for making your Tailwind v4 projects backwards compatible.

What it does

• Convert @property rules into good old CSS vars
• Pre-compute oklab() functions
• Pre-compute color-mix() functions (+ replace CSS vars inside them beforehand)
• Remove advanced instructions (colorspace) from gradients
• Provide support for nested CSS (used by dark mode or custom variants with &)
• Transform translate, scale, rotate properties to their transform: ... notation
• Add whitespace to var fallbacks var(--var,) > var(--var, ) to help older browsers understand

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.
