Introduction to HTML Headings

A. Definition of HTML Headings

In HTML, headings are defined using specific tags that range from <h1> to <h6>. These tags are used to create a hierarchy in your content, allowing users to understand the flow and importance of the information presented.

Headings are crucial for several reasons:

• Structure: They organize content into sections.

HTML provides six levels of headings, each with a specific purpose. The choice of which heading to use depends on the importance of the section it represents. Here’s a quick overview of the heading tags:

Tag	Level	Description
<h1>	1	Main Heading, usually the title of the page

<h4>	4	Smaller heading, used for further subdivisions
<h5>	5	Even smaller heading
<h6>	6	Least important heading

The <h1> tag represents the most important heading. There should only be one <h1> on any page, typically used for the main title.

The <h2> tag is used for secondary headings under the main title.

<h2>About Us</h2>
