Using the CSS will-change Property for Performance Optimization
Article Introduction：Will-change cannot be abused because it will cause additional resource consumption in the browser and prevent optimization. Its function is to inform the browser elements in advance that they will change, thereby triggering optimization mechanisms such as layer improvement and hardware acceleration. However, if you use a large number of elements or unnecessary animations, it will cause excessive memory usage and page jamming. Suitable for frequent moving UI elements (such as sliding menus, pop-up windows), drag elements, complex scrolling animations and other scenarios. Correct usage includes: specifying specific attributes instead of all; adding dynamically when necessary and removing them in time after the animation ends; and implementing mouseenter addition, mouseleave delay removal and other methods to reduce resource usage in combination with JS.
