ページの内容は、公式にあるSticky footer with fixed navbarの内容をほぼコピペしただけです。

src/App.jsx

import { useState } from 'react'
import reactLogo from './assets/react.svg'

function App() {
  const [count, setCount] = useState(0)

  return (

    <footer class="footer mt-auto py-3 bg-light">

}

export default App

これで yarn dev して http://localhost:5173/ をブラウザで開きます。
