Headings must not be empty
Headings in a page define the page structure and are an outline of the page's contents. Headings that have no text inside are a mistake.
Likely an empty heading has been used to add extra vertical space or to add a decorative element such as the gray bar under some K-State headings.
Why is this important
Search engines rely on headings to understand the meaning and structure of a page.
Assistive technologies such as screen readers use headings to aid user navigation of a page. For example, screen readers typically have a keystroke that will skip to the next heading.
