3. When some content on the page changes state in response to user operations;
4. When some content transitions between several states;
5. Guide the user to perform a certain When doing some operations, or drawing their attention to some very important information.
When animation should not be used:
1. When certain operations require users to repeat operations frequently;
2. When the device cannot fully display the animation effect (that is, the Animation will occupy a lot of computer resources and affect performance);

1. Whether the animation is suitable for your target customers;
2. Whether the animation is practical;
3. Whether the animation enhances the user experience;
4. Whether the animation runs at an appropriate speed.
