所以我正在遵循Youtube 上關於reactJS的教程,youtuber告訴我將CSS文件導入到我的index.css中,然後它應該正確顯示網站的渲染,但是,當我複製CSS並導入到我的App .js 和Index.js 中沒有彈出任何內容,有人知道如何處理這個問題嗎? React 版本的風格是否不同?我還缺少其他設定嗎?
這裡是index.css:
@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@300;400&display=swap'); * { box-sizing: border-box; margin: 0; padding: 0; } body { font-family: 'Poppins', sans-serif; } .container { max-width: 500px; margin: 30px auto; overflow: auto; min-height: 300px; border: 1px solid steelblue; padding: 30px; border-radius: 5px; } .header { display: flex; justify-content: space-between; align-items: center; margin-bottom: 20px; } .btn { display: inline-block; background: #000; color: #fff; border: none; padding: 10px 20px; margin: 5px; border-radius: 5px; cursor: pointer; text-decoration: none; font-size: 15px; font-family: inherit; } .btn:focus { outline: none; } .btn:active { transform: scale(0.98); } .btn-block { display: block; width: 100%; } .task { background: #f4f4f4; margin: 5px; padding: 10px 20px; cursor: pointer; } .task.reminder { border-left: 5px solid green; } .task h3 { display: flex; align-items: center; justify-content: space-between; } .add-form { margin-bottom: 40px; } .form-control { margin: 20px 0; } .form-control label { display: block; } .form-control input { width: 100%; height: 40px; margin: 5px; padding: 3px 7px; font-size: 17px; } .form-control-check { display: flex; align-items: center; justify-content: space-between; } .form-control-check label { flex: 1; } .form-control-check input { flex: 2; height: 20px; } footer { margin-top: 30px; text-align: center; }
這是我的 App.js 和 Index.js
import React from 'react'; import ReactDOM from 'react-dom/client'; import App from './App'; import reportWebVitals from './reportWebVitals'; import './index.css'; const root = ReactDOM.createRoot(document.getElementById('root')); root.render( <App /> ); // If you want to start measuring performance in your app, pass a function // to log results (for example: reportWebVitals(console.log)) // or send to an analytics endpoint. reportWebVitals();
最後,App.js :
import Header from "./components/Header"; import Tasks from "./components/Tasks"; import './index.css'; function App() { return ( <div className="Container"> <Header title='Orpheus Research'/> <Tasks /> </div> ); } export default App
index.css 應匯入到index.js 檔案。所以你可以直接刪除app.js中的導入。
由於您使用“./index.css”作為路徑導入,因此您需要確保index.css檔案與index.js位於同一資料夾中(我認為它是src資料夾)。
