This question was first raised in 2012, but the responses provided didn't address my specific situation (smooth transition for rearranging wrapped content).
"After removing an item from a flexbox, the remaining items snap into their new positions immediately instead of animating.
Given that the items are changing position, I would expect transitions to be applied.
I've already set the transition property on all elements involved (the flexbox and its children).
Is there a way to animate modifications (additions & deletions) in a flexbox?"
I'm particularly focused on animating the movement of flexbox items that wrap onto other rows/columns.
The desired final functionality would be similar to what is offered by Metafizzy's Isotope plugin.
