HTML Introduction
Learn what HTML is and why it is the foundation of every web page.
Syntax
<tagname>content</tagname>HTML stands for HyperText Markup Language. It is the standard language used to create and structure content on the web.
HTML is not a programming language — it is a markup language. It uses tags to tell the browser how to display text, images, links, and other content.
What you can do with HTML
- Describe the structure of a web page.
- Add headings, paragraphs, lists, links, and images.
- Build forms, tables, and interactive content.
Every website you visit — from a simple blog to a large app — is built on HTML.

When to use it
- A developer writes HTML to structure the homepage of a small business website.
- A content team uses HTML to mark up blog articles so browsers display headings and paragraphs correctly.
- A student creates a personal portfolio page using HTML as the skeleton before adding CSS styles.
