As for the transition effect of vue, the official overview given by vue is as follows.

Vue provides many different application transition effects when inserting, updating or removing DOM.

Includes the following tools:

1. Automatically apply class in CSS transition and animation

2. You can use the third-party CSS animation library together, such as Animate. css

3. Use JavaScript to directly manipulate DOM in the transition hook function

4. You can use the third-party JavaScript animation library together, such as Velocity. js

There are many examples given in it, but when the examples are given to "multiple element transition", there is no case code. Here, this part of the case in vue official document is supplemented by one part.

Here's my code
