The problem here is that steemit allows for breaking the markdown syntax, and we don't. I can probably fix most of these things (the only problem being time).
Concerning the captions, this is something I can't fix. You are using both a multiple-hastag and a "sub" environment. As a result, we got a tiny result here. This is not really a bug but a feature of the font choice. using only the sub part should be sufficient, no?
I guess the real underlying problem might be that you can't write something that will look the same on every site. Perhaps I should preface my posts with 'this post is best viewed at steemstem.io' and give a direct link to the post (tough I'd have to post it first!), as the very first line of the post, when I manage to get things looking right.
EDIT: Cos often my captions are long, and if I don't do the hashtag and sub, the lines spill over on top of each other and are unreadable. I experimented till I got something that worked. But on steemstem.io a different rationale might work better.
