Method: 1. Use the margin related attributes to set the outer margin for the div (the distance around the periphery of the div box); 2. Use the padding related attributes to set the inner margin for the div (the content loaded in the div box to the edge of the box) (distance between borders)).
The operating environment of this tutorial: Windows 7 system, CSS3&&HTML5 version, Dell G3 computer.
CSS margins (margin)
The box’s margins are divided into four directions: top, right, bottom, and left.
Outside The setting of margin is used to control the distance around the periphery of the box, and does not belong to the scope of the box itself.
The main purpose of the margin is to control the position of the box, so negative values can appear
CSS Margin Attribute
Attribute |
Description |
---|---|
margin | Abbreviation property. Set all margin properties in one statement. |
margin-bottom | Set the bottom margin of the element. |
margin-left | Set the left margin of the element. |
margin-right | Set the right margin of the element. |
margin-top | Set the top margin of the element. |

css padding
The padding of the box is divided into four directions: top, right, bottom and left
- The setting of the padding is used to control the inner margin of the box The distance between the loaded content and the edge of the box (border).
The padding of the box occupies the space inside the box, the minimum is 0, and negative values are not allowed.

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.

React is a JavaScript library for building user interfaces. Its core idea is to build UI through componentization. 1. Components are the basic unit of React, encapsulating UI logic and styles. 2. Virtual DOM and state management are the key to component work, and state is updated through setState. 3. The life cycle includes three stages: mount, update and uninstall. The performance can be optimized using reasonably. 4. Use useState and ContextAPI to manage state, improve component reusability and global state management. 5. Common errors include improper status updates and performance issues, which can be debugged through ReactDevTools. 6. Performance optimization suggestions include using memo, avoiding unnecessary re-rendering, and using us

Using HTML to render components and data in React can be achieved through the following steps: Using JSX syntax: React uses JSX syntax to embed HTML structures into JavaScript code, and operates the DOM after compilation. Components are combined with HTML: React components pass data through props and dynamically generate HTML content, such as. Data flow management: React's data flow is one-way, passed from the parent component to the child component, ensuring that the data flow is controllable, such as App components passing name to Greeting. Basic usage example: Use map function to render a list, you need to add a key attribute, such as rendering a fruit list. Advanced usage example: Use the useState hook to manage state and implement dynamics

React is the preferred tool for building single-page applications (SPAs) because it provides efficient and flexible ways to build user interfaces. 1) Component development: Split complex UI into independent and reusable parts to improve maintainability and reusability. 2) Virtual DOM: Optimize rendering performance by comparing the differences between virtual DOM and actual DOM. 3) State management: manage data flow through state and attributes to ensure data consistency and predictability.

React is a JavaScript library developed by Meta for building user interfaces, with its core being component development and virtual DOM technology. 1. Component and state management: React manages state through components (functions or classes) and Hooks (such as useState), improving code reusability and maintenance. 2. Virtual DOM and performance optimization: Through virtual DOM, React efficiently updates the real DOM to improve performance. 3. Life cycle and Hooks: Hooks (such as useEffect) allow function components to manage life cycles and perform side-effect operations. 4. Usage example: From basic HelloWorld components to advanced global state management (useContext and

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.

React is a JavaScript library developed by Facebook for building user interfaces. 1. It adopts componentized and virtual DOM technology to improve the efficiency and performance of UI development. 2. The core concepts of React include componentization, state management (such as useState and useEffect) and the working principle of virtual DOM. 3. In practical applications, React supports from basic component rendering to advanced asynchronous data processing. 4. Common errors such as forgetting to add key attributes or incorrect status updates can be debugged through ReactDevTools and logs. 5. Performance optimization and best practices include using React.memo, code segmentation and keeping code readable and maintaining dependability
