htmltype

html tag elements are: 1. The tag occupies one line, and the width and height can be specified as a block tag; 2. The tag is in one line, and the width and height are determined by the content. Only when the content exceeds the width of HTML, Inline tags that can wrap into new lines; 3. Inline block tags that have the characteristics of both inline elements and block elements.

What are the classifications of html tags?

The operating environment of this tutorial: Windows 7 system, CSS3&&HTML5 version, Dell G3 computer.

The types of HTML tags can be divided into three types: block-level tags, inline tags, and inline block tags.

Block-level label:

Block-level label: The label occupies one line, and the width and height can be specified.

Features:

Able to identify width and height
The top, bottom, left and right margins and padding are all valid for it
Can automatically wrap lines
Multiple block element tags are written together, and the default arrangement is from top to bottom
You can use margin:0 auto to center the alignment

Commonly used block elements are:

...

inline Tag:

Inline (row-level) tag: The tag is within a line. The width and height are determined by the content. Only when the content exceeds the width of HTML, it will wrap.

Features:

Unable to set width and height

Margin has no effect up and down, only left and right, padding has effect, Will expand the space; box-sizing:border-box; is invalid because this attribute is for the box model.

Will not wrap automatically

Commonly used inline elements are:

Inline block Tag:

Inline block element (inline-block) has the characteristics of both inline elements and block elements. The code display:inline-block sets the element as an inline block element. (New in css2.1), and tags are such inline block tags.

Features:

Will not wrap automatically

Can set width and height

The default arrangement is from left to right

You can use text-align:center to align the content horizontally and centrally relative to the parent box, such as the img tag, you can use text-align:center , aligned in the center relative to the parent box, margin: 0 auto invalid

arranged horizontally, but all elements will have a gap of 1 space by default because there is a carriage return written between elements in html Newline, browser parsing will parse it into a space.

Commonly used inline block elements are:

,

HTML tag types can be converted:

display:inline;Convert to inline element

display:linline-block;Convert to inline block element

display:block;Convert to block-level elements

React: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AM

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.

The Future of React: Trends and Innovations in Web DevelopmentApr 19, 2025 am 12:22 AM

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: A Powerful Tool for Building UI ComponentsApr 19, 2025 am 12:22 AM

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 React with HTML: Rendering Components and DataApr 19, 2025 am 12:19 AM

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's Purpose: Building Single-Page Applications (SPAs)Apr 19, 2025 am 12:06 AM

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: The Power of a JavaScript Library for Web DevelopmentApr 18, 2025 am 12:25 AM

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

React's Ecosystem: Libraries, Tools, and Best PracticesApr 18, 2025 am 12:23 AM

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 and Frontend Development: A Comprehensive OverviewApr 18, 2025 am 12:23 AM

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
