The operating environment of this article: Windows 7 system, HTML5 version, Dell G3 computer.
Origin of HTML:
The full English name of HTML is Hyper Text Markup Language, which is hypertext markup language. HTML is a markup language created in 1990 by Tim Berners-Lee, the inventor of the Web, and his colleague Daniel W. Connolly. It is an application of the standard generalized markup language SGML. Hypertext documents written in HTML are called HTML documents, which can be independent of various operating system platforms (such as UNIX, Windows, etc.). Using HTML, the information that needs to be expressed is written into HTML files according to certain rules, recognized by a dedicated browser, and these HTML files are "translated" into identifiable information, that is, the web page you see now.
Since 1990, HTML has been used as the information representation language of the World Wide Web. Files described using HTML need to be displayed through a web browser. HTML is a language for creating web page files. It uses markup instructions (tags) to display images, sounds, pictures, text animations, movies and other content. In fact, every HTML document is a static web page file. This file contains HTML instruction codes. These instruction codes are not a programming language, but a markup structure language that layouts the display position of data in a web page. It is easy to learn. Easy to understand and very simple. The universal application of HTML brought about the technology of hypertext - jumping from one topic to another, jumping from one page to another, and linking files to hosts around the world with the click of a mouse. Hypertext Transfer Protocol provides The rules that browsers follow and the operations they perform when running HTML documents. The formulation of HTTP enables browsers to have unified rules and standards when running hypertext.
A hypermedia document on the World Wide Web (www) is called a page (foreign language: page). The page that is the starting point for an organization or individual on the World Wide Web is called the homepage (foreign language: Homepage) or homepage. The homepage usually includes pointers (hyperlinks) to other related pages or other nodes. The so-called hyperlink is a Uniform Resource Locator (Uniform Resource Locator, foreign language abbreviation: URL) pointer, by activating (clicking) it, the browser can easily obtain new web pages. This is also one of the most important reasons why HTML is widely used. An organic collection of pages that is logically viewed as a whole is called a website (Website or Site). Hypertext Markup Language (English abbreviation: HTML) is a markup language designed for "web page creation and other information that can be viewed in a web browser."
The essence of a web page is hypertext markup language. By combining the use of other Web technologies (such as scripting languages, public gateway interfaces, components, etc.), powerful web pages can be created. Therefore, Hypertext Markup Language is the basis of World Wide Web (Web) programming, which means that the World Wide Web is built on hypertext. Hypertext Markup Language is called Hypertext Markup Language because the text contains so-called "hyperlink" points.
Definition
Hypertext markup language is an application under the standard universal markup language. It is also a specification and a standard. It uses markup symbols to mark what is to be displayed. various parts of the web page. The web page file itself is a text file. By adding tags to the text file, you can tell the browser how to display the content (such as how to process text, how to arrange pictures, how to display pictures, etc.). The browser reads the web page files in order, and then interprets and displays the marked content according to the tags. The error will not be pointed out for wrongly written tags, and the interpretation and execution process will not be stopped. The compiler can only analyze the cause of the error through the display effect. and error location. However, it should be noted that different browsers may have different interpretations of the same tag, and thus may have different display effects.

React: A Powerful Tool for Building UI ComponentsApr 19, 2025 am 12:22 AMReact 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 AMUsing 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 AMReact 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.
