HTML Introduction


HTML is a markup language for building Web pages.


What is HTML?

  • HTML stands for Hyper Text Markup Language
  • HTML is the standard markup language for building Web pages across internet
  • HTML describes the structure of a Web page
  • HTML consists of a series of tags and elements
  • HTML elements instruct the browser how to display a Web Page

A Simple HTML Document

Example Explained

  • The <!DOCTYPE html> declaration tells us and browser that this document is an HTML document
  • The <html> element is the root element of an HTML page or document
  • The <head> element contains meta tags , cdn and link files of the HTML page
  • The <title> element specifies a title for the HTML page (which is shown in the browser's title bar or in the page's tab)
  • The <body> element defines the main part of the html document, and is a container for all the visible contents, such as headings, paragraphs, images, hyperlinks, tables, lists, etc.
  • The <h1>this tag creates a large heading
  • The <p> this tag creates a paragraph

What are HTML Elements?

An HTML element includes everything between its opening tag and closing tag.

<tagname> Content goes here... </tagname>

The HTML element is everything from the start tag to the end tag:

<h1> My First Heading </h1>
<p> My first paragraph. </p>
Start tag Element content End tag
<h1> My First Heading </h1>
<p> My first paragraph. </p>
<br> none none

Note: Certain HTML elements, such as the <br> element, don't contain any content. These elements are known as empty elements. Unlike other elements, empty elements don't have an end tag.


Web Browsers

A web browser (such as Chrome, Edge, Firefox, or Safari) is designed to read HTML documents and show them accurately.

A web browser doesn't show the HTML tags, but it relies on them to figure out how to show the webpage.

View in Browser


Note: The information within the <body> section appears on a web browser. The content inside the <title> element is visible either on the browser's title bar or in the tab for the page.
