What Is HTML? The Basic Language of Every Website

HTML (HyperText Markup Language) is the standard code used to build and structure every web page — it tells a browser what each piece of content is: a heading, a paragraph, an image, or a link. HTML is not a programming language; it is a markup language, meaning it labels content so the browser knows how to display it. Every website you visit, from Google to YouTube, is built on a foundation of HTML.

How HTML Works

HTML works through tags — short keywords wrapped in angle brackets that mark where a piece of content starts and ends. For example, <h1>My Page</h1> creates a big heading, while <p>Hello!</p> makes a paragraph. Most tags come in pairs: an opening tag like <p> and a closing tag like </p>, with the content in between.

Think of HTML as the skeleton of a web page. Just as bones give a body its shape before muscles and skin are added, HTML gives a page its structure before colours (CSS) and interactivity (JavaScript) are layered on top. A child can write a real, working web page with only a few tags — for instance, <h1> for a title and <img> to show a picture. There are around 100 HTML tags in common use, but a beginner needs only a handful to build their first page.

Why It Matters for Kids

HTML is often the very first "code" children write, because they see results instantly — type a tag, refresh the browser, and their words appear on screen. This quick feedback builds confidence and supports the digital-skills goals in Malaysia's KSSR and STEM curriculum. Learning HTML also introduces structured thinking that carries into every other language.
