In this pen here:
I have an h1 element and h3 element. There is a gap between these two elements that appears, which is different from that gap that would occur between two lines of text, either plainly in the body or within a P element. Why is this and how can I affect the gap? Is this gap the same gap that would be rendered between separate elements? Is there a way to affect the gap only between a certain set of/ two particular elements?
