In web design and development, CSS (Cascading Style Sheets) and CSS3 are widely used. They are techniques for layout and style presentation. Although CSS and CSS3 may seem similar, there are many differences between them. In this article, we will discuss the differences between CSS and CSS3.
1. The difference between CSS and CSS3
- CSS3 has more modules
CSS3 is more powerful than CSS and can achieve more visual effects . CSS3 includes more modules, such as background module, text module, border module, etc., which means developers can use more attributes and values for style control.
- CSS3 has more style effects
Compared with CSS, CSS3 supports more visual styles. For example, special effects such as shadows, rounded corners, gradients, animations, etc. can all be achieved with CSS3. These new features can expand the presentation and interactive experience of the website.
- CSS3 supports media queries
CSS3 supports media queries and can customize styles according to different devices, resolutions and screen sizes to better adapt to different devices . This makes website responsive design more convenient and flexible.
- CSS3 has better compatibility
CSS3 has better compatibility than CSS. It is compatible with modern browsers such as Mozilla Firefox, Google Chrome, Safari, Opera, etc. These browsers support many CSS3 properties and rules. At the same time, if you use a browser with lower compatibility, CSS3 can also fall back to CSS better.
2. Similarities between CSS3 and CSS
- Both are used to control the style and layout of web pages
CSS and CSS3 are both used to control web pages Style and layout techniques. They allow users to customize the style and layout of web pages, making them look and feel consistent with or distinctive from the entire website.
- Both are referenced in HTML
Both CSS and CSS3 can be referenced in HTML and are used to control the appearance and style of HTML tags. CSS and CSS3 are widely used in the design and development of web pages and are considered one of the fundamental aspects of building a website.
- Both use style rules to define styles
Both CSS and CSS3 use style rules to define styles. Style rules consist of selectors and declaration blocks. In a style rule, the user can specify a selector and then define the styles that apply to the selector in the declaration block.
Conclusion
Although CSS and CSS3 are both used to control the style and layout of web pages, there are many differences between them. CSS3 has more modules and style effects, and has better compatibility. But at the same time, CSS3 and CSS also have many similarities. Users can choose which technology to use based on specific needs and browser compatibility.

HTML and React's Integration: A Practical GuideApr 21, 2025 am 12:16 AMHTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.
React and HTML: Rendering Data and Handling EventsApr 20, 2025 am 12:21 AMReact efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.
The Backend Connection: How React Interacts with ServersApr 20, 2025 am 12:19 AMReact interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.
React: Focusing on the User Interface (Frontend)Apr 20, 2025 am 12:18 AMReact is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React in the HTML: Building Interactive User InterfacesApr 20, 2025 am 12:05 AMReact can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.
React: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AMReact 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 AMReact'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.
