I wanted to use Tailwind for styling. The next.js app I created with thirdweb 's tools uses Pages Routing which is no longer recommended and I had a hard time getting Tailwind to work. So I created a new next.js app and installed Tailwind, as recommended on their docs.

Create Next.js app and Install Tailwind

npx create-next-app@latest
cd my-project
npm install -D tailwindcss postcss autoprefixer npx tailwindcss init -p

After adding tailwind app/global.css looked like this

@tailwind base;
@tailwind components;
@tailwind utilities;

:root {
  --foreground-rgb: 0, 0, 0;
  --background-start-rgb: 214, 219, 220;
  --background-end-rgb: 255, 255, 255;
}

@media (prefers-color-scheme: dark) {
  :root {
    --foreground-rgb: 255, 255, 255;
    --background-start-rgb: 0, 0, 0;
    --background-end-rgb: 0, 0, 0;
  }
}

body {
  color: rgb(var(--foreground-rgb));
  background: linear-gradient(to bottom,
      transparent,
      rgb(var(--background-end-rgb))) rgb(var(--background-start-rgb));
  padding: 2rem 4rem;
}

Add the Thirdweb and Solana Components

After installing I added the the Solana and Thirdweb dependencies to package.json

"dependencies": {
    ...,
    "@solana/wallet-adapter-react": "^0.15.24",
    "@solana/wallet-adapter-react-ui": "^0.9.22",
    "@solana/wallet-adapter-wallets": "^0.19.5",
    "@thirdweb-dev/auth": "^3.2.22",
    "@thirdweb-dev/react": "^3",
    "@thirdweb-dev/sdk": "^3"
}

Add ThirwebProvider

In /app/page.tsx I added <ThirdwebProvider> and the other components from day 4 that made it possible to claim an NFT.
