01. Welcome to HTML and the Web

HTML is the foundation of every website. In this lesson, you will learn what HTML does, how browsers read it, and how to create your first HTML file.

Learning objectives

• Explain the role of HTML in a website.
• Recognize elements, tags, and attributes.
• Create and open an index.html file.

HTML, CSS, and JavaScript

HTML provides structure, CSS controls presentation, and JavaScript adds behavior. Think of HTML as the frame of a building, CSS as its visual design, and JavaScript as its interactive systems.

Your first element

<h1>Hello, world!</h1>
<p>This is my first web page.</p>

An element usually has an opening tag, content, and a closing tag. Some elements, such as images, do not wrap text.

Practice activity

1. Create a folder named html-course.
2. Create a file named index.html.
3. Add the example above, save it, and open it in your browser.
