Hey @SBurnett28
"I could be misunderstanding how this parameter works as I imagined it would output "
I think this is the case. If you don’t zero out the border values in the theme settings HS will not do it for you. Thus allowing the default values to be rendered.
HubSpot has done a very good job of ensuring that you must be explicit when working with the style fields.
If you have any questions please don’t hesistate to reach out!
