Introduction to Web Development

Web development is built on three core technologies: HTML (structure), CSS (design), and JavaScript (logic). HTML defines the skeleton of every webpage.


You will learn how browsers read HTML, convert it into DOM, and render it visually.


Goal: Understand WHAT HTML is and WHY it matters.

Code Example
<!DOCTYPE html>
<html>
  <body>
    <h1>Hello World</h1>
  </body>
</html>
