HTML <header> Tag

The <header> tag defines the header of a page or a section. It usually contains a logo, search, navigational links, etc.

This tag doesn’t present a new section in the outline. A <header> element commonly contains the heading (an <h1>–<h6> element) of a surrounding section. However, this is not required.

The <header> tag is one of the HTML5 elements. In an HTML document, it is allowed to use several <header> tags, which can be placed in any part of it.

It is not permitted to place the <header> tag inside the <footer> and <address> elements, and in another <header> tag.

Syntax

The <header> tag comes in pairs. The content is written between the opening (<header>) and closing (</header>) tags.

<!DOCTYPE html>
