I am creating a react app where I use vite, tailwind and shadcn ui and get an error

Question

I get an error in my react app; I am creating a react app where I use vite tailwind and shadcn ui

[plugin:vite:css] [postcss] C:/Users/DENZEN Computer/OneDrive/Documents/React-30-Days-Challenge/SastaInsta/src/globals.css:3:1: The bg-dark-1 class does not exist. If bg-dark-1 is a custom class, make sure it is defined within a @layer directive.

This error mentions that bg-dark-1 is not a class but it is a class.

I also check network tab and I see that the globals.css file is not load and error 500. I don't now what is the problem here

I want to set up the react app with vite, tailwind, and shadcn. I just install the button from shadcn and place it to my code

I can't see any references to bg-dark-1 in your codebase or in the tailwind documentation for background colors

You could either use a predefined color (like bg-slate-950 for a dark color), or add a custom one in your tailwind.config.js like so:

/** @type {import('tailwindcss').Config} */
module.exports = {
  theme: {
    colors: {
      'dark': {
        1: '#07090c',
        2: '#25323f',
        // ...
      },
      // ...
    },
  },
}

(as explained further in tailwinds documentation here)
