Pop a menu or shop window open with a bounce that does not flip it when closing

A little overshoot makes a window feel alive, but the same bounce on the way out can push it past nothing and show it mirrored for a moment, or leave an invisible window that still catches clicks. Here is how to open lively and close cleanly.

Why this works

Overshoot feels lively on the way in, but on the way out it pushes the picture past nothing and turns it inside out. Using different springs for opening and closing, and stopping at zero, keeps the playfulness where it belongs.

When not to use it

Skip the bounce for windows that open often or hold serious things, like settings, warnings or purchase confirmations. The extra swing slows people down, so use a quick plain fade that is finished at once.
