What Is HTML?
Whenever you open a website, the page you see is built using HTML. It defines the structure of web pages by organizing text, images, links, videos, forms, and other content.
HTML stands for HyperText Markup Language. It is the standard markup language used to create and structure web pages on the internet.
In simple words, HTML is the skeleton of a website. Just as a human skeleton gives shape to the body, HTML gives structure to a web page. CSS is used to style the page, and JavaScript adds interactivity.
Whether you’re creating a personal blog, business website, e-commerce store, or web application, HTML is the first language every web developer learns.

Why Is HTML Important?
HTML is the foundation of every website. Without HTML, browsers would not know how to display web content.
Reasons Why HTML Is Important
- Creates the structure of web pages
- Displays text, images, videos, and links
- Works with CSS and JavaScript
- Supported by all modern web browsers
- Easy to learn for beginners
- Essential for web development
- Helps improve website accessibility and SEO when used correctly
How Does HTML Work?
HTML uses tags to tell the browser how different parts of a webpage should be organized.
The process works like this:
- You write HTML code in a text editor.
- Save the file with the .html extension.
- Open the file in a web browser.
- The browser reads the HTML code.
- The browser displays the webpage.
Browsers interpret HTML—they do not display the code itself.
Basic Structure of an HTML Document
Every HTML page follows a basic structure.
<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset=”UTF-8″>
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
<title>My First Web Page</title>
</head>
<body>
<h1>Welcome to HTML</h1>
<p>This is my first HTML page.</p>
</body>
</html>
Explanation
- <!DOCTYPE html> – Declares the document as HTML5.
- <html> – The root element of the webpage.
- <head> – Contains metadata such as the title and character encoding.
- <title> – Displays the page title in the browser tab.
- <body> – Contains all visible webpage content.
Common HTML Tags
HTML includes many tags for different types of content.
Heading Tags
