In HTML, headings are used to define the structure and hierarchy of your web page content. They allow you to organize your content into different sections and convey the importance of each section. HTML provides six levels of headings, ranging from <h1> to <h6>, with <h1> being the highest level and <h6> the lowest.
Headings should be used to indicate the main sections of a web page. For example, you might use a <h1> tag for the page title,a <h2> tag for the main heading of the page, and <h3> tags for the subheadings of the main heading.
It is important to use headings consistently throughout your web page. This will help users to understand the structure of your page and to find the information they are looking for.
Examples
<!DOCTYPE html>
<html lang="en">
<head>
<title>My Heading-Only Web Page</title>
</head>
<body>
<h1>Main Heading</h1>
<h2>Subheading 1</h2>
<h3>Sub-subheading 1.1</h3>
<h4>Sub-sub-subheading 1.2</h4>
<h5>Sub-sub-subheading 1.3</h5>
<h6>Sub-subheading 1.4</h6>
</body>
