Headings in HTML are used to define the hierarchy and structure of the content on a web page. There are six different heading tags available in HTML, ranging from <h1> to <h6>. Here’s how you can use these tags:

1 – <h1> tag: The <h1> tag is used for the main heading of the page, and should only be used once per page. Here’s an example:
<h1>Welcome to my Website</h1>


2 – <h2> to <h6> tags: The <h2> to <h6> tags are used for subheadings, with <h2> being the second-level heading and <h6> being the sixth-level heading. These tags should be used in descending order of importance to define the hierarchy of the content. Here’s an example:

<h2>About Us</h2>
<h3>Our Team</h3>
<h4>John Smith</h4>
<h5>Marketing Manager</h5>
<h6>Phone: 123-456-7890</h6>
In this example, "About Us" is the second-level heading, "Our Team" is the third-level heading, "John Smith" is the fourth-level heading, "Marketing Manager" is the fifth-level heading, and "Phone: 123-456-7890" is the sixth-level heading.


It’s important to use heading tags properly to ensure that your content is well-structured and easily understood by users and search engines. Remember to use the appropriate heading level for the content, and to only use each heading level once per page in a hierarchical order.
