• <header> - Defines a header for a document or a section
• <nav> - Defines a set of navigation links
• <section> - Defines a section in a document
• <article> - Defines an independent, self-contained content
• <aside> - Defines content aside from the content (like a sidebar)
• <footer> - Defines a footer for a document or a section
• <details> - Defines additional details that the user can open and close on demand
• <summary> - Defines a heading for the <details> element
