Hello Team,
I am not sure if this is a bug or if it is by design. When using a Cards template in Classic Report and switching Layout to FLOAT then the last card in the list is always a few pixels larger (high) than the rest of the cards.
You can also see that in the Universal Theme demo (https://apex.oracle.com/pls/apex/apex_pm/r/ut/card-templates)
Thanks,
Lior
