                Tailwind v4 polyfill / browser compatibility configuration
              
          

        

      

        


      

      

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


What it does


    

  • Effectively getting browser support down to Chrome 99 (and basically everything supporting @layer)
    • 

  • 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
    •
