Which tags define headings in HTML, ranging from h1 to h6?

The correct answer refers to heading tags in HTML, which include a range from h1 to h6. These tags are fundamental in structuring content on a webpage, allowing for hierarchical organization of information.

The h1 tag represents the most important heading, while h2 through h6 denote progressively less significant headings. This system not only helps with visual presentation but is also crucial for search engine optimization (SEO) and accessibility, as it provides a clear outline of the content structure to both users and search engine crawlers.

The other choices do not accurately describe this function. Header tags may colloquially refer to headings, but they are not the correct term recognized in HTML documentation. Title tags specifically pertain to the title element within the head of an HTML document and do not relate to headings. Section tags refer to the

element used to define sections in an HTML document but do not correspond to heading levels. Thus, heading tags is the most accurate and relevant term to describe the range of headings used in HTML.
