The HTML <h1> through <h6> Tags are used to define headings in an HTML document. The <h1> tag is the highest-level heading and the <h6> tag is the lowest-level heading.

Headings are used to giving structure to an HTML document and make it easier for users to navigate and understand the content. They also help search engines understand the hierarchy and importance of the content on a page.

Here is an example of how to use the <h1> through <h6> Tags:

<h1>Heading 1</h1>
<h2>Heading 2</h2>
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>

The text within a heading tag is usually displayed in a larger and bolder font than the surrounding text. The exact appearance of the headings will depend on the style sheet that is applied to the HTML document.

It’s important to use headings appropriately and in a logical order. The <h1> the tag should be used for the main heading on a page, and the <h2> through <h6> tags should be used for subheadings in descending order of importance.
