I thought the following, which I said in another posting, might be of interest here:HTML, in its page design aspects, is essentially the same as the system of markup codes that is used in the field of book publishing. We call first-level headings "h1," second-level ones "h2," etc. and similarly for all other design elements of a book.
This system was in use in book publishing long before it was used on the Internet!
