An element represents a complete, structured unit in an HTML document. It includes the opening tag, content, and closing tag, forming a distinct part of the document structure, like <'p'>This is a paragraph.<'/p'>.
Structure	Tags exist in pairs, consisting of an opening tag (e.g., <'p'>) and a closing tag (e.g., <'/p'>). Some tags, like line break <'br'>, are self-closing and do not have a closing tag.	Elements encompass the entire structure, including the opening tag, content, and closing tag. The combination of these parts forms a complete HTML element.
Usage	Tags are used to define specific actions or formatting within an HTML document. They act as the fundamental components of HTML elements.	Elements are used to represent structured content within the HTML document. They provide semantic meaning to different parts of the content.
Representation	Tags are the individual markers that appear in the HTML source code, indicating the beginning or end of an element.	Elements are the complete units that users see when viewing a web page. They represent the structured content on the page.
As an example	<'p'>, <'h1'>, <'a'>, <'img'>, <'br'>	<'p'>This is a paragraph.<'/p'>, <'h1'>Heading1<'/h1'>, <'a href="https://example.com"'>Link<'/a'>, <'img src="image.jpg" alt="Image"'>, <'br'>
