Introduction to HTML

What is HTML?

Welcome to your first step in our interactive HTML course! If you’ve ever asked “What is HTML?” or wanted to learn HTML free, you are in the right place. Every website you visit, from a simple blog to a complex web application, is built using HTML. This HTML tutorial will teach you the core concepts of web development with hands-on examples.

HTML stands for HyperText Markup Language.

• HyperText means that it contains links (hyperlinks) that connect webpages to one another.
• Markup Language means it uses “tags” to annotate text, telling the web browser how to structure and display the content.

HTML is not a programming language like Python or JavaScript. Instead, it is a structural language. It tells the browser, “This is a heading,” “This is a paragraph,” or “This is an image.”

The Three Pillars of the Web

To understand HTML’s role, it helps to see how it works alongside the two other core web languages: CSS and JavaScript.

Think of building a webpage like building a house:

1. HTML (The Structure): This is the foundation, walls, and roof. It defines where the rooms are and what they are used for. In a webpage, HTML defines the text, images, links, and layout structure.
2. CSS (The Styling): This is the paint, decorations, and interior design. CSS (Cascading Style Sheets) makes the HTML look beautiful by adding colors, fonts, spacing, and animations.
3. JavaScript (The Behavior): This is the electricity and plumbing. JavaScript adds interactivity, allowing the page to respond to user actions (like clicking a button, submitting a form, or fetching live data).

How HTML Works

HTML uses tags to label pieces of content. Most tags have an opening tag and a closing tag, wrapping around the content they affect.

Syntax / Structure

<tagname>Content goes here...</tagname>

Code Example

Here is a very simple example of an HTML tag making text a paragraph:

<p>This is a paragraph of text.</p>

Code Explanation:

• <p> is the opening tag. It tells the browser that a paragraph is starting.
• This is a paragraph of text. is the actual content.
• </p> is the closing tag. It has a forward slash / to indicate that the paragraph has ended.

Try It Yourself

You can write HTML and see it render immediately in your browser.

Key Takeaways

• HTML (HyperText Markup Language) is the standard markup language for documents designed to be displayed in a web browser.
• HTML provides the structure of a webpage.
• HTML works alongside CSS (for styling) and JavaScript (for interactivity).
• HTML uses tags (like <p> and </p>) to structure content.
