@richtabor Getting some strange behavior with the padding controls. Not sure this feature is ready to use yet.

Color controls are working well!

[richtabor]

Currently there's no programmatic indicator of the padding controls (like there are for most other attributes), so our theme's default padding is overriding the functionality of the inline styles. I opened an issue on the Gutenberg repo WordPress/gutenberg#24337 to get one added; that way we can check for that class and contain our padding styles as the default/standard application (as it should be) and if a user applies a custom padding, it'll be 100% right.

Works perfectly
