@Quoth - yeah, I wasn't just referring to the html tag <blockquote> but rather more broadly to the concept of "blockquotes": blocks of quoted text within the body of a main text. (In fiction, this is often going to be something like quoted verse or epistolary text.) I was trying to understand the strongly stated proscription against
all margins, as I'm struggling to see how that would work. As I said, no margins at all would result in headings running into body text (with perhaps font-size as the only distinguishing factor between them?) and ditto for blockquoted text. But maybe I'm not correctly visualizing the JSWolf's formatting implications.
