Commenter “elle” is trying to find a book that’s “kind of like a manual on how to design interiors.”
Like why you use a space break, why you indent certain amounts, why chapters start new right and things that break down the skeleton of a book. It’s something that is never really taught and you kind of do these things without a reason why, its simply because “you just do.” Do you know why a part opener always starts new right backed blank? I don’t. I just know it does.
Why do we have double breaks? Why does the text start flush left afterwards?
Anyone? Anyone? The usual books I recommend are The Elements of Typographic Style and The Complete Manual of Typography, but neither of these goes into the reasons behind design conventions, as far as I can recall.
