In text editors, html, etc. the default mode of sub title spacing seems to quite equal. Why is that?
To clarify, we have an end paragraph of a subsection and a new subsection with title and opening paragraph. Looking like this:
p1
h3
p2
Now the spacing between p1 and h3, and, h3 and p2 is usually by default equal or near to equal. Why is that? Is there some typography lesson to be had? To me it just looks plain wrong.
