Why does CSS3 have animation function? Analysis from the perspective of performance and customizability

In recent years, with the rapid development of Internet technology, the design of web pages has increasingly focused on user experience and visual effects. In order to achieve richer interactive effects, CSS3 introduced animation functions. This article will analyze why CSS3 has animation functions from two perspectives: performance and customizability.

First of all, performance is a factor that cannot be ignored. Traditional web animation is usually implemented through JavaScript, but because JavaScript is an interpreted language, it runs slowly. CSS3 animations are processed by the browser's rendering engine, which can perform animation effects faster. This is because CSS3 animation is implemented through hardware acceleration, and the browser can use the computer's GPU to accelerate rendering, with higher performance. In contrast, using JavaScript to implement animation may cause page freezes and performance issues, affecting the user experience.

Secondly, CSS3 animations are more customizable. CSS3 provides a wealth of animation effects and operation properties. Developers can customize animation speed, delay, pause, repeat and other parameters according to their own needs. In addition, CSS3 also supports keyframe animation, which can set different styles at different points in time to achieve more complex animation effects. In contrast, using JavaScript to implement animation requires writing tedious code and is less flexible. CSS3 animation can be implemented through a concise CSS style sheet, making the adjustment of animation effects more convenient and faster.

In addition, CSS3 animation also provides better cross-platform support. Because CSS3 animations are parsed and rendered by the browser, consistent animation effects can be achieved across various devices and browsers. Whether on the desktop or mobile, whether the user is using a mainstream browser such as Chrome, Firefox, Safari or Edge, CSS3 animations can run well. This provides developers with wider applicability and a better user experience.

However, despite the many advantages of CSS3 animation, there are also some shortcomings. First of all, CSS3 animation is relatively cumbersome to implement complex animation effects. Developers need to write more CSS code and conduct compatibility testing between different browsers, which may require additional work and time costs. Secondly, since CSS3 animation is processed by the browser, the running effect and performance will also be affected by the browser version and device performance. On some low-end devices, CSS3 animations may be stuck and delayed.

To sum up, from the perspective of performance and customizability, CSS3’s animation function is of great significance. CSS3 animation can better achieve rich interactive effects and improve user experience and visual effects. Because CSS3 animations have higher performance and better customizability, developers can more easily achieve the animation effects they want and maintain consistency across various devices and browsers. However, developers also need to pay attention to its limitations when using CSS3 animations, and choose animation effects reasonably to avoid unnecessary performance consumption. Overall, CSS3 animation brings more possibilities and flexibility to web design and is a very valuable technology.
