What HTML is
HTML (HyperText Markup Language) is the language you use to describe the structure of a page. It does not care about colors or layout — that is CSS — but about what is on the page: headings, text, images, links, buttons.
Basic syntax
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Hello</title>
</head>
<body>
<h1>Welcome</h1>
<p>A <a href="/about">first page</a>.</p>
</body>
</html>Key concepts
- Tags: open and close (
<p>...</p>). - Attributes: add info (
href,alt,lang). - Nesting: tags can contain other tags.
Using the right tag for the right content is the foundation of accessibility and SEO.
