What is HTML?

Understand what HTML stands for, how it works, and its role in building web pages.

What is HTML?

HTML stands for HyperText Markup Language. It is the standard language used to create and structure content on web pages.

Breaking Down the Name

WordMeaning
HyperTextText that contains links to other text or pages — clicking a link takes you somewhere else
MarkupA way of annotating text to define its structure — using "tags" to label content
LanguageA set of rules and syntax that browsers understand

What Does HTML Do?

HTML tells the browser what each piece of content is. It does not control how things look (that's CSS) or how things behave (that's JavaScript). HTML defines structure.

  • This text is a heading
  • This text is a paragraph
  • This is a link
  • This is an image
  • This is a list

HTML Is NOT a Programming Language

A common misconception: HTML is not a programming language. It cannot make decisions, loop through data, or perform calculations. It is a markup language — it simply describes the structure of content.

How HTML Works

  1. You write HTML code in a text file (with a .html extension)
  2. You open that file in a web browser
  3. The browser reads (parses) the HTML
  4. The browser renders the page visually on screen

A Quick Example

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

When you open this in a browser, you see a large heading that says "Hello, World!" followed by a paragraph.

The Role of HTML in Web Development

Think of building a house:

  • HTML = the structure (walls, rooms, doors, windows)
  • CSS = the decoration (paint, wallpaper, furniture placement)
  • JavaScript = the functionality (electricity, plumbing, smart home features)

All three work together, but HTML comes first.

Key Takeaways

  • HTML stands for HyperText Markup Language
  • It defines the structure and content of web pages
  • It is not a programming language — it's a markup language
  • Browsers read HTML files and render them visually
  • HTML works alongside CSS (styling) and JavaScript (interactivity)
