What to read about indents, fonts in layouts and layout in Web design?

Question

css

I have been developing and layout for a long time. But still did not understand the laws of indentation, the percentage of the font height and other things. How to know what is the distance between lines of text, what are the distances between headings H1 H2, etc. Between list items. Between paragraphs P Indents subblocks.
What to read to understand exactly how it should be? Because I don't think designers do everything by sight. Of course, there are typographic frameworks, but as the font changes, the meaning is immediately lost.
It is also interesting about typography, the selection of the number of fonts, styles. How to limit yourself, how much?
Of course, there are many similar books, but studying everything is stupid. You need to start with the basic and best, and then you yourself understand what to study next.
Thank you.

Answer 2

Read Dmitry Kirsanov's web design. By typography, you can look at a selection of books on Lebedev's website (you can find it yourself in Google), but be careful, there are also complex books that you should not start with.
How to make it beautiful on paper - the book is good, but boring, I mastered it on the second try. In addition, there is mainly for printing (as the name implies), but you seem to need a web.
