Complete HTML Tutorial
Master HTML - the standard markup language for creating web pages
Getting Started with HTML
HTML (HyperText Markup Language) is the foundational language used to create and structure content on the web. Whether you're building a personal blog, a corporate website, or a web application, HTML provides the basic structure that allows content to be displayed in a browser.
What is HTML?
HTML is not a programming language—it's a markup language. It tells the browser how to display text, images, videos, and other forms of content. HTML uses elements (also called "tags") to wrap and identify pieces of content so they appear or behave in a certain way.
What You'll Learn
- What HTML is and why it's important
- How HTML documents are structured using tags
- Basic HTML elements like headings, paragraphs, and links
- How to create and view your first HTML page
- How HTML works with CSS and JavaScript to create dynamic websites
HTML in Action: Your First Web Page
Let’s look at a basic HTML page. This example shows the simplest structure needed for a functional web page.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My First Page</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is my first HTML page.</p>
</body>
</html>
Explanation:
- <!DOCTYPE html> – Declares the document type and HTML version.
- <html> – Root element of the HTML document.
- <head> – Contains metadata like the page title and character encoding.
- <title> – The title shown on the browser tab.
- <body> – Contains all the visible content of the webpage.
- <h1> – A top-level heading.
- <p> – A paragraph of text.
How to Create Your First HTML Page
- Open a simple text editor (like Notepad, VS Code, or Sublime Text).
- Copy the example code above into the editor.
- Save the file as
index.html. - Open the file in your browser by double-clicking it.
Why Use HTML?
- Foundation of all web pages: Every website starts with HTML.
- Easy to learn: Its syntax is simple and beginner-friendly.
- Cross-browser support: All modern browsers support HTML5.
- Works with CSS & JavaScript: HTML provides structure, CSS handles style, and JavaScript adds interactivity.
- Essential for developers: Every front-end developer must know HTML.
Fun Fact 💡
HTML was created by Tim Berners-Lee in 1991. It has evolved significantly over the years, with HTML5 being the latest major standard, supporting video, audio, and rich semantic tags.
What’s Next?
Now that you know the basics of what HTML is and what it does, the next step is to dive into the structure of an HTML document and start learning about individual elements in detail.
HTML Introduction
What is HTML?
HTML stands for HyperText Markup Language. It is the core technology used to create the structure of web pages. HTML uses a system of tags to mark up and organize content such as text, images, links, and multimedia elements.
The term HyperText refers to the ability to link to other documents or resources on the web, while Markup Language refers to the way text is annotated with tags to define how it should appear or behave.
Why is HTML Important?
Without HTML, a browser wouldn't know how to render the content on a web page. HTML works in tandem with CSS (for styling) and JavaScript (for interactivity) to form the foundation of all websites and web apps.
Key Characteristics
Markup Language
HTML uses tags like <h1>, <p>, and
<a> to define and label elements such as headings,
paragraphs, and links.
Structure
HTML outlines the document's content and hierarchy, helping browsers and developers understand how data is organized.
Universal Standard
HTML is supported by all modern web browsers and devices, making it a universal standard for web development.
Interactive with Other Tech
HTML integrates seamlessly with CSS for styling and JavaScript for dynamic functionality, forming the web development trio.
Basic Components of an HTML Page
- DOCTYPE Declaration – Tells the browser which HTML version to use (e.g.,
<!DOCTYPE html>for HTML5). - <html> – The root element that contains all content.
- <head> – Contains meta-information like the page title, charset, and linked resources.
- <body> – The section where all visible content like text, images, and buttons is placed.
Try it yourself:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My Page</title>
</head>
<body>
<h1>Welcome!</h1>
<p>Edit this code to practice.</p>
</body>
</html>Browser Preview
Welcome!
Edit this code to practice.
Did You Know? 🧠
The first version of HTML was created by Tim Berners-Lee in 1991. It originally had only 18 tags! Today’s HTML5 supports multimedia, semantic elements, offline storage, and much more.
HTML Versions
- HTML 4.01: Widely adopted version before HTML5.
- XHTML: Stricter, XML-based syntax.
- HTML5: Current standard with support for video, audio, canvas, and APIs.
Next Steps
Now that you've been introduced to HTML, the next section will guide you through the history of HTML, showing how it evolved into what we use today.
HTML History
The Evolution of HTML
HTML has come a long way since its inception in 1991. From a simple markup language with only a handful of tags, it has evolved into a powerful foundation for the modern web. Here's a brief look at its journey through the years:
HTML 1.0
Developed by Tim Berners-Lee, HTML 1.0 introduced the concept of
hyperlinks and basic text formatting. It had only 18 tags like
<p>, <a>, <br>, and
<h1>.
HTML 2.0
This version was the first official specification published by the IETF (Internet Engineering Task Force). It standardized existing HTML practices and added support for forms, tables, and basic formatting.
HTML 3.2
Published by the W3C, HTML 3.2 introduced new elements like
<table>, <applet>, and
<script>. It added support for scripting (JavaScript) and better
control over page layout and text flow.
HTML 4.01
This version introduced three "flavors": Strict, Transitional, and Frameset. It
promoted the separation of content and style by encouraging the use of CSS, and
deprecated many presentational tags (like <font>).
XHTML
XHTML was a reformulation of HTML 4.01 using XML syntax. It required stricter coding practices (like closed tags and lowercase elements) but wasn't widely adopted due to browser inconsistencies.
HTML5
HTML5 revolutionized web development. It introduced semantic elements
(<header>, <article>), native support for
multimedia (<audio>, <video>), offline
storage, and powerful APIs like geolocation, drag-and-drop, and canvas for graphics.
HTML5.2 and Beyond
Modern HTML is continuously evolving. New elements like <dialog>
and expanded accessibility support have been added. The focus is now on performance,
mobile-friendliness, and progressive web apps (PWAs).
Summary
- HTML 1.0: The birth of the web with basic tags and hyperlinks.
- HTML 2.0–4.01: Rapid growth with new features and layout tools.
- XHTML: XML-based strict standard (less adopted).
- HTML5: Semantic, multimedia, and application-level features.
- Today: HTML continues to power the modern web with regular updates and improvements.
Fun Fact: The W3C (World Wide Web Consortium) and WHATWG (Web Hypertext Application Technology Working Group) now collaboratively maintain the HTML standard.
