Flexbox layour with listing of articles

I learn flexbox and need help with fiddle : https://jsfiddle.net/6y4akmL3/
it was 1 hostel with header, content, commands footer with cells “cell 2:1:1” : https://jsfiddle.net/26fet4vu/
I tried to remake it in listing of hostels and wrap them with hostel_items_listings_container class and hostel_item_container
for any hostel item, but with it commands footer with cells “cell 2:1:1” lost its position at bottom of any block item : https://prnt.sc/oac0yz
Could you please to take a look ?
