What is a section header?

A section header is a title or label that identifies and introduces a section in a document or webpage. It is usually placed at the top of the section and indicates the topic or subject matter covered. Section headers can also be used to break up lengthy documents into more manageable chunks and make it easier for readers to navigate and locate specific information. They can be formatted in a variety of ways, including bold, underlined, or in a larger font size. In technical writing or academic papers, section headers may follow a specific format or numbering system to indicate the hierarchy of the information.
