changing text padding in CSS

hi,

All headings and paragraphs seem to have padding (a H3 heading, for instance, is followed by some 6px of padding).

How can I change this? Advanced styling doesn’t have options to change it.

If I use CSS, will this work:
h3 {
padding: 0px 0px
}

and where exactly should I add this extra CSS code?

Thanks!
