Thanks very much for this. Yes, it seems you're right about the latter.

I've already been haughtily reprimanded today by a Sigil developer on here for not basically already knowing how to solve the problem I was raising - and have since found elsewhere online lots of references to how Sigil isn't very user-friendly etc. So, with that in mind, my apologies if this seems like an ignorant question, but can I ask: What do you mean by "change the CSS class used for the notes in the stylesheet..."? I mean, I know what all of those things mean individually; I'm just not sure how I should change the code. Would you be able to point me to any simple online guide to this kind of stuff?

A sort of side-note: It seems that resources for people who want to publish their own book but aren't too familliar with coding are pretty good, if the text in question is very simple - a novel, maybe with a few displayed passages and one or two pictures. But if you need to do anything more sophisticated, involving notes and other bits of paraphernalia that scholarly books require, there's not much out there. I guess people learn what they need to do within publishing houses, but, if you're a freelance, all of the books (and there are hardly any in the last few years) that purport to teach you how to put together an epub file using CSS/HTML, "from scratch", etc., basically seem to assume you just want to format a very simple novel. Again, if you know of any general resources for more advanced, complex texts, I'd be very grateful to know.

I'd pay decent money for a good, comprehensive video course that really went into detail.
