What is HTML?
HTML stands for HyperText Markup Language. It is the skeleton of every single webpage on the internet. Without HTML, your browser would just show a blank white screen — no text, no images, nothing. Not even Google.
The Three Amigos of the Web
HTML 🦴The skeleton — structure and content. "What is on the page?"
CSS 🎨The skin — colors, fonts, layout. "How does it look?"
JavaScript ⚡The muscles — behaviour, clicks, live data. "What does it do?"
Your First Real Webpage
Example 1 — 10 Lines. A Real Webpage.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"/> <title>My First Page</title> </head> <body> <h1>Hello World!</h1> <p>I am learning HTML at CIWeb.</p> </body> </html>
Hello World!
I am learning HTML at CIWeb.
That is literally it. 10 lines = a real webpage that any browser in the world can open.
How Tags Work
Example 2 — Opening, Closing, Self-Closing Tags
<!-- Most tags: opening + content + closing --> <h1>This is a heading</h1> <p>This is a paragraph.</p> <strong>This is bold.</strong> <!-- Self-closing: no content, just attributes --> <br/> <!-- Line break --> <img src="cat.jpg" alt="A cat"/> <!-- Image --> <meta charset="UTF-8"/> <!-- Meta info -->
Rule: Opening =
<p> Closing = </p> (note the /)
The / before the tag name means "end of this tag". Self-closing tags like <br/> need no closing tag because they have no content.
A Real Blog Card in 5 Lines of HTML
Example 3 — Like Cards on CIWeb
<article> <h2>AI Kya Hai? Complete Guide 2026</h2> <p>Artificial Intelligence ek machine ka dimag hai...</p> <a href="blog-ai.html">Read More →</a> </article>
This IS the actual HTML behind blog cards. By Lesson 5 you will build one from scratch.
Fun Fact
There are 1.9 billion websites on the internet. Every single one uses HTML. Facebook, YouTube, Netflix — all HTML at the core. You are learning the language of the entire internet.
Who Made HTML?
Tim Berners-Lee created HTML in 1991 to share scientific documents. He never patented it. He gave it to the world for free. That is why the web exists today and why you can learn it at CIWeb for free.
