How to modify html
In today's digital world, web design and programming are very important skills. By understanding HTML (Hypertext Markup Language), you can easily create your own website or modify an existing one. Let's discuss how to modify HTML.
First, open the web page you want to modify. You can open the web page source code by right-clicking the page in your browser and selecting "View Source" or by opening a text editor. Once you have the source code for your web page, you can start making changes.
Secondly, understand the structure of HTML code. HTML consists of various tags and attributes. Tags tell the browser how to display text or images, and attributes tell the browser how to display tags. For example,
is a title tag, and attributes can be used to change the color or size of the title. Other commonly used tags include
(paragraph tag), (image tag), (link tag), etc.
Next, you can start making modifications. For example, if you wanted to change the color of the heading, you could use the attribute like this:
This is a red heading
If you want to add an image to your web page, you can use the image tag, as shown below:
Among them, the "src" attribute specifies the URL address of the image, and the "alt" attribute is an alternative text that will be displayed when the image cannot be loaded.
Finally, check your changes. After you've made all the changes, save the file and refresh the browser to see if your changes have taken effect. Also, if you're not sure if the modifications you've made are correct, you can use an HTML validator to check if there are problems with your code.
In general, HTML is an easy language to learn. As long as you have certain skills and experience, you can easily create and modify web pages. I hope this article was helpful and empowered you to better leverage this skill to create better user experiences and visuals.

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.

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 components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.

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.

The React ecosystem includes state management libraries (such as Redux), routing libraries (such as ReactRouter), UI component libraries (such as Material-UI), testing tools (such as Jest), and building tools (such as Webpack). These tools work together to help developers develop and maintain applications efficiently, improve code quality and development efficiency.

The advantages of React are its flexibility and efficiency, which are reflected in: 1) Component-based design improves code reusability; 2) Virtual DOM technology optimizes performance, especially when handling large amounts of data updates; 3) The rich ecosystem provides a large number of third-party libraries and tools. By understanding how React works and uses examples, you can master its core concepts and best practices to build an efficient, maintainable user interface.

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.

React's main functions include componentized thinking, state management and virtual DOM. 1) The idea of componentization allows splitting the UI into reusable parts to improve code readability and maintainability. 2) State management manages dynamic data through state and props, and changes trigger UI updates. 3) Virtual DOM optimization performance, update the UI through the calculation of the minimum operation of DOM replica in memory.
