Chapter 1 — Introduction to HTML

What is HTML?
HyperText Markup Language — the standard language for creating web pages. It defines the structure and content of a page using elements (tags).
Basic building blocks:
- Element = <tag>content</tag> (most have opening & closing tags).
- Attributes add extra info: <a href="url">link</a>.
Document structure (skeleton): <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Page Title</title> </head> <body>  </body> </html>
Head vs Body:
- <head>: metadata, page title, links to CSS, meta tags.
- <body>: visible content (text, images, links).
Common text elements: headings (<h1>–<h6>), paragraphs (<p>), line breaks (<br>), horizontal rule (<hr>).

Why semantic HTML matters: accessibility, SEO, and maintainability (use elements for their intended purpose).
