所以我正在遵循 Youtube 上关于reactJS的教程,youtuber告诉我将CSS文件导入到我的index.css中,然后它应该正确显示网站的渲染,但是,当我复制CSS并导入到我的 App.js 和 Index.js 中没有弹出任何内容,有人知道如何处理这个问题吗? React 版本的风格是否不同?我还缺少其他设置吗?
这里是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; }
这是我的 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();
最后,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 应导入到index.js 文件中。所以你可以直接删除app.js中的导入。
由于您使用“./index.css”作为路径导入,因此您需要确保index.css文件与index.js位于同一文件夹中(我认为它是src文件夹)。
