<header> Tag in HTML
FREE
Overview
In HTML, many components or tags are provided for writing the body section, footer section, and so on semantically. Similarly, to include the header section in any portion of the HTML section, HTML5 includes a header tag to indicate that the components included within this tag comprise the header section. If the tags are used correctly, the web browser can tell the difference between HTML and plain text.
HTML tags are essential elements while building webpages. To learn more about such tags in HTML refer here.

How To Use Header Tag In HTML?
The header tag is a block-level element, and it represents introductory content or navigational content on the web pages. It is useful for holding content like website heading, section heading, website's logo, etc.
The basic syntax of the <header> tag is shown below:
Note: A header element represents the header of the content. However, it cannot be used inside the <footer>, <address>, or parent <header> element.
For example, if you paste the below code in HTML Validator you'll get the error.
Error: The element header must not appear as a descendant of the footer element.
Let's see what contents you can include inside the header tag in HTML:
-
Information about the author
Example:
-
Images or logo
Example :
-
Heading elements (h1 to h6)
Example :
Note:
- The <header> element is the visible section on the web pages whereas the <head> element is different from the <header> element which contains metadata that is not shown to the users. Do not confuse the <header> element with the <head> element.
The <header> element is not used for the sectioning of the content, i.e., if you want to create a new section on the web page and separate this section from the rest of the sections available on the web pages, then the <header> element is not the right choice to achieve this.
Instead, the <header> element is primarily used to contain the headings, images or logos, etc. of the surrounding section, but this is not a compulsion to use the <header> element. There can be several <header> elements in one document.
Attributes
The <header> tag does not have any specific attribute. But, like all the other HTML tags, the <header> tag supports the global attributes in HTML5.
Some of the attributes are given below:
- accesskey
- draggable
- contextmenu
- hidden
- style
- xml:lang etc.
