React cannot parse css because when webpack configures the loader of the "css/less" file, modularization is not enabled by default or due to the incorrect introduction method. The solution: 1. Change the loader configuration of webpack ; 2. Introduce it through "@import '~antd/dist/antd.css';" in the "index.css" file.
The operating environment of this tutorial: Windows 10 system, react18.0.0 version, Dell G3 computer.
What should I do if react cannot parse css?
#react Modular introduction of external css files does not take effect Problem handling
When introducing external css/less files into react, if you directly Import=》import “./search.less”;
Just use className directly when using it, as shown below:
But if you use this Import styles =》import styles from “./search.less”;
You will find that the styles do not take effect, as shown below:
The reason is, When webpack configures the loader of css/less files, modularization is not enabled by default. The introduction of this modular approach requires changing the loader configuration of webpack, as shown below:
Introducing antd style into React does not take effect?
When writing code, I think it is more convenient to use antd components (although antd is also very airtight)
This has happened before, because I downloaded antd The problem that arises is that the source using npm cannot be used in China. You can use Taobao's mirror source. If it still doesn't work, use the hotspot of your mobile phone to download it.
But this time there was a problem that the antd style did not take effect. I installed antd several times. I tried npm, cnpm, and yarn, but the problem still persisted. Nope
So I searched online, but none of the solutions seemed to be right. Then I went to the official website to check the introduction method
There is the following statement:
My code is written in other folders under scr, and the js file does not create a corresponding css file. There should be no need to introduce antd/dist/antd.css
So I thought it should be introduced in the css of the entry file index file, and it became
Solution:
1. Check whether antd is introduced successfully
Try a few more times. If there are too many warns, it means it is suspended
npm i antd cnpm i antd yarn add antd
2. Introduce in the index.css file:
@import '~antd/dist/antd.css';

To integrate React into HTML, follow these steps: 1. Introduce React and ReactDOM in HTML files. 2. Define a React component. 3. Render the component into HTML elements using ReactDOM. Through these steps, static HTML pages can be transformed into dynamic, interactive experiences.

React’s popularity includes its performance optimization, component reuse and a rich ecosystem. 1. Performance optimization achieves efficient updates through virtual DOM and diffing mechanisms. 2. Component Reuse Reduces duplicate code by reusable components. 3. Rich ecosystem and one-way data flow enhance the development experience.

React is the tool of choice for building dynamic and interactive user interfaces. 1) Componentization and JSX make UI splitting and reusing simple. 2) State management is implemented through the useState hook to trigger UI updates. 3) The event processing mechanism responds to user interaction and improves user experience.

React is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.

The relationship between HTML and React is the core of front-end development, and they jointly build the user interface of modern web applications. 1) HTML defines the content structure and semantics, and React builds a dynamic interface through componentization. 2) React components use JSX syntax to embed HTML to achieve intelligent rendering. 3) Component life cycle manages HTML rendering and updates dynamically according to state and attributes. 4) Use components to optimize HTML structure and improve maintainability. 5) Performance optimization includes avoiding unnecessary rendering, using key attributes, and keeping the component single responsibility.

React is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent

React is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.

React combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.
