Article Introduction：The key to improving user experience in CSS animation is to choose transition and @keyframes reasonably. 1. Transition is suitable for simple state changes, such as button hover effect, which is achieved by defining attributes, duration, delay and speed curves; 2. @keyframes is suitable for complex animation sequences, such as loading animations, which controls the state of elements at different time points through multiple keyframes. Usage tips include: prioritizing the use of transform and opacity to improve performance, ensuring the initial consistency is consistent with the target state, and setting the ease function reasonably. Frequently asked questions: enable hardware acceleration in a timely manner and reduce nesting, check the property name and initial value when the transition does not take effect, and repeat animation playback can be performed through inf
