Is there any way to edit the layout of standard webparts?

[Erik Wettergren]

I find it hard to get a consistent layout of our pages since different webparts take up different amount of space. Some, like Stream and Forms webparts, have lots of unnecessary whites pace, and others do not. I would really like to have the ability to tweak the layout of any webpart somehow, kind of like using JSON for formatting list columns.

Any ideas?

No, it's not possible

OK - what I suspected.

Thanks for a very clear answer :)
