1
Build named sections
Build this first target: <section>; <h2> inside <section> (id="schedule") containing “Schedule”. Inspect the structure before checking the lesson.
Hint & worked example
A section groups a distinct topic. aria-labelledby can give the region its name from a visible heading.
The requested elements, attributes, content, and hierarchy exist outside comments.
```
<section><h2 id="schedule">Schedule</h2></section>
```
Common mistake to avoid: A visual appearance alone guarantees the intended HTML meaning.
2
Extend the named sections example
Extend your file to include: <section> (aria-labelledby="schedule"); <h2> inside <section> (id="schedule") containing “Schedule”. Inspect the structure before checking the lesson.
Hint & worked example
A section groups a distinct topic. aria-labelledby can give the region its name from a visible heading.
The requested elements, attributes, content, and hierarchy exist outside comments.
```
<section aria-labelledby="schedule"><h2 id="schedule">Schedule</h2></section>
```
Common mistake to avoid: Replacing semantic elements with generic divs automatically improves accessibility.
3
Verify the complete named sections pattern
Finish the pattern with: <section> (aria-labelledby="schedule"); <h2> inside <section> (id="schedule") containing “Schedule”; <p> inside <section> containing “Practice begins at ten.”. Inspect the structure before checking the lesson.
Hint & worked example

```
<section aria-labelledby="schedule"><h2 id="schedule">Schedule</h2><p>Practice begins at ten.</p></section>

Understand the pattern

A section groups a distinct topic. aria-labelledby can give the region its name from a visible heading.

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

<section aria-labelledby="schedule"><h2 id="schedule">Schedule</h2><p>Practice begins at ten.</p></section>

A section groups a distinct topic. aria-labelledby can give the region its name from a visible heading.

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 named sections?Replacing semantic elements with generic divs automatically improves accessibility.A section groups a distinct topic. aria-labelledby can give the region its name from a visible heading.A visual appearance alone guarantees the intended HTML meaning.

Apply it elsewhere

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

Keep the momentum.

Complete the lab, then explain and apply the pattern.
