This is a simple Tailwind plugin to expose all of Tailwind's colors, including any custom ones, as custom css properties on the :root element.
There are a couple of main reasons this is helpful:
- You can reference all of Tailwind's colors—including any custom ones you define—from handwritten CSS code.
- You can define all of your colors within the Tailwind configuration, and access the final values programmatically, which isn't possible if you did it the other way around: referencing custom CSS variables (defined in CSS code) from your Tailwind config.
