HTML tags are element names surrounded by angle brackets:-
TWO TYPES OF TAGS IN HTML:-
  • PAIRED TAGS (Open AND Close    Ex:-  <HTML> </HTML>)
  • UNPAIR TAGS (Ex:-  <br>)
HTML tags normally come in pairs like <p> and </p>
The first tag in a pair is the start tag, the second tag is the end tag
The end tag is written like the start tag, but with a forward slash inserted before the tag name

Tip: The start tag is also called the opening tag, and the end tag the closing tag.
