Installation

Install dependencies

npm i framer-motion clsx tailwind-merge @radix-ui/react-label @tabler/icons-react

Add util file

utils/cn.ts
import { ClassValue, clsx } from "clsx";
import { twMerge } from "tailwind-merge";
 
export function cn(...inputs: ClassValue[]) {
  return twMerge(clsx(inputs));
}

Modify the config file to add a plugin and a box shadow

tailwind.config.ts
const defaultTheme = require("tailwindcss/defaultTheme");
 
const colors = require("tailwindcss/colors");
const {
  default: flattenColorPalette,
} = require("tailwindcss/lib/util/flattenColorPalette");
 
/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ["./src/**/*.{ts,tsx}"],
  darkMode: "class",
  theme: {
    // rest of the code
    extend: {
      boxShadow: {
        input: `0px 2px 3px -1px rgba(0,0,0,0.1), 0px 1px 0px 0px rgba(25,28,33,0.02), 0px 0px 0px 1px rgba(25,28,33,0.08)`,
      },
    },
  },
  plugins: [addVariablesForColors],
};
 
function addVariablesForColors({ addBase, theme }: any) {
  let allColors = flattenColorPalette(theme("colors"));
  let newVars = Object.fromEntries(
    Object.entries(allColors).map(([key, val]) => [`--${key}`, val])
  );
 
  addBase({
    ":root": newVars,
  });
}
