Can a heading tag have an ID?

An id on a <header> tag assigns an identifier to the header. The identifier must be unique across the page.

How many headings should you have to identify content?

In practice, on most web pages, you'll likely only need between one and three heading levels. Try to ensure that each heading level accurately identifies the structure of your page content: The level should reflect the depth of a section.

Does header have a closing tag?

The basic tag is written like this <header></header> with the header content nested inside the opening and closing tags. This could include the section's heading (an <h1> - <h6> element), but this is optional.

How do you structure headings?

Use headings hierarchically , with the <h1> representing the most important idea on the page, and sub-sections organized with <h2> level headings. Those sub-sections can themselves be divided with <h3> level headings, and so on. It is best to plan out a heading structure before composing a page.
