The HTML Skeleton
Concept
The HTML Skeleton
Every HTML page starts with a doctype, then html, head, and body tags. The head holds metadata and the body holds visible content.
The doctype isn't a tag in the usual sense — it's a signal that tells the browser to render the page in modern standards mode instead of an old quirks mode meant for compatibility with ancient pages.
- Explain the core idea behind The HTML Skeleton.
- Predict output before running a change.
- Test one realistic and one unusual input.
- Use the result to make the next decision.
- 1. Read one concept.
- 2. Change the example.
- 3. Run, compare, and explain.
- 4. Complete the challenge below.
Self-check before continuing
Without looking at the example, describe what changes when you modify one input in The HTML Skeleton. Then reopen the editor and prove your explanation with a small test.
You are ready to continue when you can predict, test, and explain the result.
Your turn
Write a minimal HTML page with your name as the title and a heading that says Welcome.
Ask about this lesson or your next move. The guide explains the path without taking the work away from you.
