Which heading tag is typically used for a subsection of a major section?

The use of heading tags in HTML helps to create a structured hierarchy that aids in both accessibility and SEO. For a subsection of a major section, Heading 3 is the appropriate choice.

When organizing content, the hierarchical structure typically begins with Heading 1 for the main title of the document, followed by Heading 2 for major sections or chapters. Heading 3 then serves as a subsection within one of those major sections, thus effectively indicating a breakdown of topics or ideas within that context.

By using Heading 3 for subsections, it communicates the importance and relationship of the content to both users and assistive technologies. This hierarchy not only improves readability for users but also allows screen readers to navigate the document more effectively, ensuring that vital information is easily accessible.
