This sort of stuff was difficult to figure out when I was learning HTML/CSS, do you know of any guides which list similar rules and how to make "proper" use of properties like borders, padding, typography etc?
Not to make a value judgement on ebooks, but I just really like physical books sometimes - if it was on Amazon I likely would have bought it.
Again, not a value judgement on the content - I'm sure it's great (I'm a paid and happy user of TailwindUI)
