Heading Tags

HTML provides six levels of headings, each defined by <h1> through <h6>, with <h1> being the most important and <h6> being the least important.

Characteristics of HTML Headings:

<h1>: The largest and most important heading. Typically used for the main title of the page or section.

<h2>: Slightly smaller than <h1>, used for subheadings or section titles.

<h3>: Smaller than <h2>, used for subsections.

<h4>: Even smaller, used for further subdivisions.

<h5>: Smaller than <h4>, used for less significant headings.

<h6>: The smallest heading, used for the least important headings or sub-sections
