Perspective boxes / spacing

Hi all! I am pleased to be here.
Very new to web building and webflow in general.

I have couple of questions, on which some enlightenment would be of great help.

First off I want to use the perspective function in my website so to create a 3d effect when opening the boxes. So far I got to the point where its working and adaptive, but i dont know how to get rid of the space between two elemens, maybe someone has idea how this can be done?

And the second question is, is it always that all the child elements in the perspective box must also be in perspective?

The published version link i attached bellow.
Any answers would be of great help!

Thanks! :pray:
