1
Build complete page outline
Build this first target: <header>; <nav> inside <header> (aria-label="Primary"); <a> inside <nav> (href="/web/") containing “Web”. Inspect the structure before checking the lesson.
Hint & worked example
A clear page outline separates site navigation, the primary task, and supporting information.
The requested elements, attributes, content, and hierarchy exist outside comments.
```
<header><nav aria-label="Primary"><a href="/web/">Web</a></nav></header>
```
Common mistake to avoid: A visual appearance alone guarantees the intended HTML meaning.
2
Extend the complete page outline example
Extend your file to include: <header>; <nav> inside <header> (aria-label="Primary"); <a> inside <nav> (href="/web/") containing “Web”; <main>; <h1> inside <main> containing “Workshop outline”; <section> inside <main>; <h2> inside <section> containing “Practice”; <p> inside <section> containing “Build an accessible page.”. Inspect the structure before checking the lesson.
Hint & worked example
A clear page outline separates site navigation, the primary task, and supporting information.
The requested elements, attributes, content, and hierarchy exist outside comments.
```
<header><nav aria-label="Primary"><a href="/web/">Web</a></nav></header>
<main><h1>Workshop outline</h1><section><h2>Practice</h2><p>Build an accessible page.</p></section></main>
```
Common mistake to avoid: Replacing semantic elements with generic divs automatically improves accessibility.
3
Verify the complete complete page outline pattern
Finish the pattern with: <header>; <nav> inside <header> (aria-label="Primary"); <a> inside <nav> (href="/web/") containing “Web”; <main>; <h1> inside <main> containing “Workshop outline”; <section> inside <main>; <h2> inside <section> containing “Practice”; <p> inside <section> containing “Build an accessible page.”; <footer>; <p> inside <footer> containing “End of workshop.”. Inspect the structure before checking the lesson.

Misconceptions to reject

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

Worked example and expected result

<header><nav aria-label="Primary"><a href="/web/">Web</a></nav></header>
<main><h1>Workshop outline</h1><section><h2>Practice</h2><p>Build an accessible page.</p></section></main>
<footer><p>End of workshop.</p></footer>

A clear page outline separates site navigation, the primary task, and supporting information.

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

Apply it elsewhere
