Fix margin+padding between title and sub-cards

[ThomDietrich]

Hey there,
Assuming that vertical-stack-in-card should behave and feel identical to the core cards, there is one very obvious difference:

The distance between the title and the first card should certainly be reduced. Equally I would argue to reduce the distance between cards, however I understand that this might squish certain card types together unpleasantly!?

I was able to resolve this by adding the following CSS rule (as applied in the core source). I am not a CSS expert, so please evaluate whether it's the best solution. Thanks!!

vertical-stack-in-card div#states.card-content {
  margin-top: -8px;
  padding-top: 0px;
}

Thank you, I was looking for exactly this. Any expert who could point me how to achieve the same for a specific card using card-mod (or maybe the card "styles" option) ? Thank you !
