What is a proper use of heading structure in HTML?

Using headings hierarchically for organization is essential for creating a clear and accessible content structure in HTML. Headings (h1, h2, h3, etc.) serve not just as design elements but as meaningful indicators of content relationships and hierarchies. When headings are used appropriately, they help convey the organization of the content to both users and assistive technologies, such as screen readers.

Proper heading structure starts with a single h1 element, which typically represents the main title of the document, followed by h2 elements for major sections, h3 elements for subsections, and so forth. This hierarchy provides users with a roadmap to navigate through the content easily, ensuring they can find the information they need quickly. It also plays a crucial role in SEO, as search engines use heading structure to determine the relevance and context of the content.

Using headings randomly or employing a single heading style misses the opportunity to leverage this organizational hierarchy, which can lead to confusion for users, particularly those relying on assistive technologies. Making all headings the same size disregards their semantic purpose and undermines the page's accessibility. Thus, the correct approach is to use headings hierarchically, ensuring that the structure is intuitive and accessible to all users.
