Header Element: Sectional Header Content
The <header> HTML element is used to define the introductory section of a document or a section within it, such as an article, a page, or a section of a webpage. This element typically contains navigational links, headings, logos, or other introductory content. The <header> is a semantic element that helps organize content, providing a clear structure and context for the section it introduces.
