css3 animation is not software. CSS animation is to gradually change elements from one style to another. It is realized through CSS and HTML language; the essence of CSS animation is that the animation properties can gradually change from one style to another. When a value changes to another value, the animation attribute can be used in conjunction with the animation attribute to achieve CSS animation effects.

css3 animation is not software
CSS can animate HTML elements without using JavaScript or Flash! .
What is CSS animation
Animation makes an element gradually change from one style to another.
You can change as many CSS properties as you like.
To use CSS animation, you must first assign some keyframes to the animation.
Keyframes contain the style that an element has at a specific time.
Some CSS properties are animatable, which means they can be used for animations and transitions.
Animated properties can gradually change from one value to another, such as size, quantity, percentage, and color.
@keyframes Rules
If you specify a CSS style in the @keyframes rule, the animation will gradually change from the current style to the new style at a specific time.
For animation to take effect, the animation must be bound to an element.
The following example binds the "example" animation to the
<!DOCTYPE html>
<html>
<head>
<style>
div {
width: 100px;
height: 100px;
background-color: red;
animation-name: example;
animation-duration: 4s;
}
@keyframes example {
from {background-color: red;}
to {background-color: yellow;}
}
</style>
</head>
<body>
<p><b>注释：</b>本例在 Internet Explorer 9 以及更早的版本中无效。</p>
<div></div>
<p><b>注释：</b>当动画结束后，会变回最初的样式。</p>
</body>

React: The Power of a JavaScript Library for Web DevelopmentApr 18, 2025 am 12:25 AMReact 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 AMThe 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 AMReact 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
The Power of React in HTML: Modern Web DevelopmentApr 18, 2025 am 12:22 AMThe application of React in HTML improves the efficiency and flexibility of web development through componentization and virtual DOM. 1) React componentization idea breaks down the UI into reusable units to simplify management. 2) Virtual DOM optimization performance, minimize DOM operations through diffing algorithm. 3) JSX syntax allows writing HTML in JavaScript to improve development efficiency. 4) Use the useState hook to manage state and realize dynamic content updates. 5) Optimization strategies include using React.memo and useCallback to reduce unnecessary rendering.
Understanding React's Primary Function: The Frontend PerspectiveApr 18, 2025 am 12:15 AMReact's main functions include componentized thinking, state management and virtual DOM. 1) The idea of componentization allows splitting the UI into reusable parts to improve code readability and maintainability. 2) State management manages dynamic data through state and props, and changes trigger UI updates. 3) Virtual DOM optimization performance, update the UI through the calculation of the minimum operation of DOM replica in memory.
Frontend Development with React: Advantages and TechniquesApr 17, 2025 am 12:25 AMThe advantages of React are its flexibility and efficiency, which are reflected in: 1) Component-based design improves code reusability; 2) Virtual DOM technology optimizes performance, especially when handling large amounts of data updates; 3) The rich ecosystem provides a large number of third-party libraries and tools. By understanding how React works and uses examples, you can master its core concepts and best practices to build an efficient, maintainable user interface.
React vs. Other Frameworks: Comparing and Contrasting OptionsApr 17, 2025 am 12:23 AMReact is a JavaScript library for building user interfaces, suitable for large and complex applications. 1. The core of React is componentization and virtual DOM, which improves UI rendering performance. 2. Compared with Vue, React is more flexible but has a steep learning curve, which is suitable for large projects. 3. Compared with Angular, React is lighter, dependent on the community ecology, and suitable for projects that require flexibility.
Demystifying React in HTML: How It All WorksApr 17, 2025 am 12:21 AMReact operates in HTML via virtual DOM. 1) React uses JSX syntax to write HTML-like structures. 2) Virtual DOM management UI update, efficient rendering through Diffing algorithm. 3) Use ReactDOM.render() to render the component to the real DOM. 4) Optimization and best practices include using React.memo and component splitting to improve performance and maintainability.
