1. Let’s first take a look at the difference between the

tag and the
tag:

The

2. Let’s now look at another aspect of the difference between the header tag and the footer tag:

header element:

represents a set of instructive content for its nearest parent element. The parent element of the header may be a sectioning element (artic, section, aside, etc.) or a root element (body element). When the closest parent element of the header element is the body element, the header element represents a set of instructive content for the entire HTML page. If there is a new area of content in the HTML document, you can add header elements according to the needs of the content. Doing so will improve the semantics of the document.

footer element:

represents the content of the supplementary description of its nearest parent element. The parent element of footer may be a section element or a root element.

The content of the footer element is usually related to the content of the current region, such as: relevant links, copyright information, etc. of the content of the current region.

When the nearest parent element of the footer element is the body element, then the footer element represents the supplementary description of the entire HTML page.

The footer element is usually used to mark some extended information of the page content, such as appendices, terms, version information, license agreement, or other content.

Here is another example of the difference between header tags and footer tags:
