Three implementation methods: 1. Use the style attribute in the html tag to define the css style; 2. Write the css style in the "" tag in the header of the html file; 3. , introduce external CSS style files through the "" tag.
The operating environment of this tutorial: Windows7 system, CSS3&&HTML5 version, Dell G3 computer.
CSS styles are referenced in 3 ways. They are defined inline, linked to internal CSS and linked to external CSS.
1. Inline definition
Inline definition, that is, using the object's style attribute within the object's tag to define the applicable style sheet attributes. The format is defined as: <p style="content"></p>
, the following example
The browser displays the content at this time
2. Link to internal CSS
The link within CSS is made by <style></style> The
tag pair is placed in . There is a type attribute type in
<style type="text/css"> /*这里写CSS内容*/ </style>
The example is as follows:
The rendering is as follows:
3. Link external CSS
css external link is to place the CSS file outside the web page, and make the CSS file effective for the style of this web page through the link , which is equivalent to in C language .h
file. The attributes in
include type, rel, and href, where type is fixed to text/css
, and rel (ie, style sheet) is fixed to stylesheet
. href naturally refers to the address of the css file. The syntax format is:
<link type="text/css" rel="stylesheet" href="css文件的存放地址">
The sample code is as follows:
The content of web.css is
The effect is as follows

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.

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.
