It can contain the aforementioned headings, table of contents, logo or information about the author. There is often more than one header element in an HTML document, but each must be in a different section advertising database It should contain information useful in terms of introducing the main content or in terms of navigation. A header is a container tag for other elements.

HTML Header - Elements
The <header> tag does not replace H1-H6 headings. At most, it can contain them. It is sometimes confused with <head>, which is the section in the code where the <title> and <description> tags are located , and where, for example, the Google tag code is inserted.
