Pop-up block effect?

Question

Vue.js

On pure css, and js I know several implementation methods, I wonder how to make a pop-up window on Vue.
There is a button, our block behind the screen, when you press the button, a window pops up from below. Click on the button in the window, and the window floats back down the screen.
Can you please tell me how to do this in Vue?

Answer 1

transition + one variable in state
That's all you need.
