In CSS3, you can use the "animation-timing-function" attribute to set the animation rotation speed. This attribute is used to specify how the animation will complete a cycle and set the speed curve of the animation. The syntax is "element {animation- timing-function:speed attribute value;}".
The operating environment of this tutorial: Windows 10 system, CSS3&&HTML5 version, Dell G3 computer.
How to set animation rotation speed in css3
animation-timing-function specifies how the animation will complete a cycle.
The speed curve defines how long it takes for the animation to change from one set of CSS styles to another.
Speed curve is used to make changes smoother.
Default value: ease
The syntax is:
animation-timing-function: value;
The mathematical function used by animation-timing-function is called cubic Bezier curve, speed curve. With this function, you can use your own values, or use one of the predefined values:
Property values are as follows:
linear The speed of the animation from start to end Are the same. Test
ease Default. The animation starts at a slow speed, then speeds up, then slows down before ending. Test
ease-in The animation starts at a slow speed. Test
ease-out The animation ends at a slow speed. Test
ease-in-out The animation starts and ends at a slow speed. Test
steps(int,start|end) specifies the number of intervals (steps) in the time function. There are two parameters. The first parameter specifies the number of intervals of the function, which is a positive integer (greater than 0). The second parameter is optional and indicates whether the animation is continuous from the beginning or end of the time period. The meanings are as follows: start: means to start directly. end: Default value, indicating an abrupt end.
cubic-bezier(n,n,n,n) The own value in the cubic-bezier function. Possible values are numeric values from 0 to 1.
The example is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
.div1{
width:100px;
height:100px;
background-color:pink;
animation:fadenum 5s;
animation-timing-function:ease-in-out;
}
@keyframes fadenum{
100%{transform:rotate(360deg);}
}
.div2{
width:100px;
height:100px;
background-color:pink;
animation:fadenums 5s;
animation-timing-function:linear;
}
@keyframes fadenums{
100%{transform:rotate(360deg);}
}
</style>
</head>

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.
React in Action: Examples of Real-World ApplicationsApr 17, 2025 am 12:20 AMReact is widely used in e-commerce, social media and data visualization. 1) E-commerce platforms use React to build shopping cart components, use useState to manage state, onClick to process events, and map function to render lists. 2) Social media applications interact with the API through useEffect to display dynamic content. 3) Data visualization uses react-chartjs-2 library to render charts, and component design is easy to embed applications.
Frontend Architecture with React: Best PracticesApr 17, 2025 am 12:10 AMBest practices for React front-end architecture include: 1. Component design and reuse: design a single responsibility, easy to understand and test components to achieve high reuse. 2. State management: Use useState, useReducer, ContextAPI or Redux/MobX to manage state to avoid excessive complexity. 3. Performance optimization: Optimize performance through React.memo, useCallback, useMemo and other methods to find the balance point. 4. Code organization and modularity: Organize code according to functional modules to improve manageability and maintainability. 5. Testing and Quality Assurance: Testing with Jest and ReactTestingLibrary to ensure the quality and reliability of the code
React Inside HTML: Integrating JavaScript for Dynamic Web PagesApr 16, 2025 am 12:06 AMTo integrate React into HTML, follow these steps: 1. Introduce React and ReactDOM in HTML files. 2. Define a React component. 3. Render the component into HTML elements using ReactDOM. Through these steps, static HTML pages can be transformed into dynamic, interactive experiences.
The Benefits of React: Performance, Reusability, and MoreApr 15, 2025 am 12:05 AMReact’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: Creating Dynamic and Interactive User InterfacesApr 14, 2025 am 12:08 AMReact 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.
