What is a heading?

A heading is a title or heading given to a section of a document, webpage, or other publication. Headings are typically formatted in a larger or bold font size and are used to provide a brief summary or introduction to the content that follows. They are often used to break up long blocks of text and make it easier for readers to navigate and understand the information presented. Headings can also help improve the search engine optimization (SEO) of a webpage or document by making it easier for search engine algorithms to understand the content and rank it accordingly.
