Change cards internal padding

Sorry it’s kind of a dumb question, but I can’t figure out how to do it. I can easily change it’s external padding/margins, but not the internal one for whatever reason. Any help is appreciated

Create a class in your css file like this
.no-padding {
padding: 0 !important;
}

In your html element, add that class.
Or other situation that could help is to verify if the element inside the card doesn’t a margin. If so change padding to margin: 0 !important; for that specific element.
