Hello colleagues! Please be loyal, I know about Google.
Does anyone know of good sources of important information on Web Design? Now you need to find typography guides, learn these basics. For deepening, I think it will not be difficult to find the necessary literature on your own.

Answer 2

As for grids - the question is not simple.
The most complete description, in order to understand the principle itself, can only be found in the literature on printing (most often, book). In the 70s-80s, even a separate excellent book-album was published, in my opinion, it was called "Modular Grid".
Search the archives of design and printing magazines: Print Magazine, [HOW], etc. There were problems in the books of Krichevsky (or articles, I don’t remember exactly).
