Hi @NoCodeDev, thanks for the great question.
At the moment it is not yet possible natively to make an evaluation of some conditions when an interaction occurs, i.e. it is not possible to have one interaction trigger another interaction (or not trigger) based on the other element’s value or style.
I am looking forward to great things in the future, take a peek at what’s coming: Announcing Memberships, Logic, and more at No-Code Conf 2021 | Webflow Blog
With custom code you can use for example, the jQuery click event by class name to trigger the interaction that is also using class based targeting.
Then in custom code you could do your conditional logic and trigger the interaction necessary to make the cards flip or not, such as “if two cards match that have some same value or attribute etc, then both should be visible, else trigger the card flip to hide the card face”
Just thinking out loud on this, I try to do most things using nocode, and it is easy to use click events to trigger mouse click interactions.
Webflow allows to use custom code in the following places:
1. In the Head or Footer of custom code in Project or Page settings
2. In a Custom Code Embed element placed in the page body on the canvas
3. In a Rich Text field in the CMS
I hope this helps to give some idea there.
