Presence of headings 

Headings should be used to provide better navigation in the document. There is a possibility that "P" tags, which have been styled to look like titles and sub-titles, have been used instead of heading tags. This quality check warns if the document contains no headings.

To resolve this quality check, use headings for titles and sub-titles.
