Open this article and note the Attempt 1 and Attempt 2 headings. Most likely, the heading line will be broken in to two, so you should see something like this:
Attempt 1: App-controlled access
(realms)
(Sorry, Tangled won't let me paste a screenshot.)
Particularly, note the spacing between the two lines of the heading. My suggestion is that we should reduce this, because headings in general should be tighter than body text. Typographer Oliver Schöndorfer demonstrates the rationale for this in this video and this article.
If you think this makes sense, I'll be happy to experiment with different values, test across different publications and come up with a PR.
Thanks yeah I think this could make sense! Main thing is we'd want to test across both drafts (editor) and published posts, and the handful of different default font options. I think there may be some inconsistencies with things like overall header size in drafts vs published posts as well, probably useful to keep an eye out if you take a closer look for a PR.
