Which term refers to the HTML elements used in a web page including tags and attributes?

The term that refers to the HTML elements used in a web page, including tags and attributes, is indeed 'Tag.' In HTML, tags are the fundamental building blocks that define the structure and content of a web page. Each tag can have attributes that provide additional information about the element, influencing how it is displayed or what behavior it may have.

For example, in the simple tag <a href="https://example.com">Link</a>, the <a> is the tag, while href is an attribute that specifies the destination of the link. Tags can create all sorts of content types, from headings and paragraphs to links and images, and they lay out the content that's visible to users.

Other terms like 'Marker,' 'Container,' and 'Segment' do not broadly define the concept of HTML elements. While 'Container' could refer to elements like <div> that encapsulate other content, it doesn’t encompass the full range of HTML structures like tags and their attributes. Similarly, 'Segment' and 'Marker' lack specific association with the fundamental components of HTML.
