026 * The h2 element represents a second-level heading in a document or section. It is used to
027 * mark up subsections or secondary headings that are hierarchically below h1 elements. The h2
028 * element is typically used to organize content into major sections and is important for
029 * creating a logical document structure. It is typically rendered in a smaller font size than
030 * h1 but larger than h3 elements.
