What is HTML?

Learn how HTML tags describe the structure of a web page.

You will learn

  • Understand what HTML does
  • Use opening and closing tags
  • Nest elements correctly

HTML (HyperText Markup Language) is the skeleton of every website. It is not a programming language — it describes what is on the page: headings, paragraphs, images, and links.

Tags come in pairs

Most tags wrap content: <p>Hello</p>. The opening tag starts the element, the closing tag ends it with a slash.
