How to use the html header?

There are for example 2 completely different sections, one section there is another section of reviews for example with information about the team...each section starts with a header h1 and h1 by, for example, there are headers smaller, that is, in the section I pointed out the h1 and h2 title , typeset next section that is below where I can no longer use h1 and h2 or can? just know that after the title example h3 no h1 heading, this rule applies to sections or even the entire layout?

"H1" or "h1" is not "html header" and "tag to indicate a header in the text." They can be put anywhere.

There is an optional rule:
  • H1 is the document title
  • H2 is a section header
  • H3 are headings of subsections
and so on...

Well, if I correctly understand the question.
