1
Build launch checklist
Build this first target: <html> (lang="en"); <head> inside <html>; <title> inside <head> containing “Workshop launch guide”; <body> inside <html>. Inspect the structure before checking the lesson.
Hint & worked example
A static page needs clear metadata and crawlable links; testing rendering alone does not verify HTTP behavior or indexing.
The requested elements, attributes, content, and hierarchy exist outside comments.
```
<html lang="en"><head><title>Workshop launch guide</title></head><body></body></html>
```
Common mistake to avoid: A visual appearance alone guarantees the intended HTML meaning.
2
Extend the launch checklist example
Extend your file to include: <html> (lang="en"); <head> inside <html>; <title> inside <head> containing “Workshop launch guide”; <meta> inside <head> (name="viewport", content="width=device-width, initial-scale=1"); <body> inside <html>; <main> inside <body>; <h1> inside <main> containing “Workshop launch guide”. Inspect the structure before checking the lesson.

```
<html lang="en"><head><title>Workshop launch guide</title><meta name="viewport" content="width=device-width, initial-scale=1"></head><body><main><h1>Workshop launch guide</h1></main></body></html>
```
Common mistake to avoid: Replacing semantic elements with generic divs automatically improves accessibility.
3
Verify the complete launch checklist pattern
Finish the pattern with: <html> (lang="en"); <head> inside <html>; <title> inside <head> containing “Workshop launch guide”; <meta> inside <head> (name="viewport", content="width=device-width, initial-scale=1"); <body> inside <html>; <main> inside <body>; <h1> inside <main> containing “Workshop launch guide”; <a> inside <main> (href="/web/") containing “Browse all lessons”. Inspect the structure before checking the lesson.

Understand the pattern

A static page needs clear metadata and crawlable links; testing rendering alone does not verify HTTP behavior or indexing.

Misconceptions to reject

A visual appearance alone guarantees the intended HTML meaning.
Replacing semantic elements with generic divs automatically improves accessibility.

The preview is a sanitized subset, not a full browser compatibility test.

Worked example and expected result

<html lang="en"><head><title>Workshop launch guide</title><meta name="viewport" content="width=device-width, initial-scale=1"></head><body><main><h1>Workshop launch guide</h1><a href="/web/">Browse all lessons</a></main></body></html>

A static page needs clear metadata and crawlable links; testing rendering alone does not verify HTTP behavior or indexing.

Try a variation

Adapt the final example to a different project name while retaining its structure and relationships. A different context still needs a real browser and accessibility check.

Explain it

Which statement correctly explains launch checklist?A visual appearance alone guarantees the intended HTML meaning.Replacing semantic elements with generic divs automatically improves accessibility.A static page needs clear metadata and crawlable links; testing rendering alone does not verify HTTP behavior or indexing.

Apply it elsewhere

You reuse launch checklist in a different project. What must still be verified?Only whether the source code has the same number of lines.The meaning, relationships, and accessible names in the new document.Nothing; passing a single exercise guarantees every future use.

Keep the momentum.

Complete the lab, then explain and apply the pattern.
