I’m not a CSS expert, but I would like to make a snippet that would universally set the point size for headers (#, ##, ###, etc.) so I could use that snippet when I try out different templates. I prefer header point size to be the much larger than ordinary body text. So for me, that would be body text==14pt, ### == 16pt, ##==16pt, and #==18pt.
(I searched “header point size snippet” and didn’t find any posts that looked like the answer.)
