According to MDN,

HTML (HyperText Markup Language) is the most basic building block of the Web. It defines the meaning and structure of web content. Other technologies besides HTML are generally used to describe a web page's appearance/presentation (CSS) or functionality/behavior (JavaScript).

Take this analogy for example
HTML serves as the structural base for any website, just like how human beings have no form without a skeletal structure, websites are formless as well without HTML.

Examples of HTML only websites include



<!DOCTYPE html> is a tag that declares the type of the document.


<html> is the container for all the HTML elements on a webpage(except the Doctype).


<head> is a container for information about the document.


<title> defines the title for the document.


<body> contains the body content of the document.
