Inconsistent behavior when working with default styles

[jonschr]

So, I'd like to add some default styles for AB containers (just to speed up adding sections on sites). This works pretty well, and here's the scss I'm using, which affects the backend and frontend and mostly works fine (I'm sure it can be improved):

All it does it set padding and max innerwidth defaults, on both frontend and backend, for a fullwidth container block when that container block is not nested within anything.

Here's the issue I run into: on both the frontend and backend of the site, updating the padding values overrides my styles here. Perfect! Except when the padding is set to 0px on any side. If I set the padding to top 20%, bottom 0%, left 10%, right 10% using the Gutenberg UI, then the markup on the frontend only outputs the top, left, and right values – when the value is 0, it doesn't output at all.

And that's actually the key here. An empty selection shouldn't be treated the same as 0% (not outputting anything). Empty means "default," not "0."

In short, my question is whether that's a change you'd consider making.
