Integrate header, nav, main and footer into a coherent document. Semantic structure should describe meaning, not visual appearance.
Correct example✓
<!doctype html>
<html lang="en">
<head><meta charset="UTF-8"><title>Local workshop</title></head>
<body>
<header><h1>Local workshop</h1><nav><a href="#services">Services</a></nav></header>
<main id="services"><h2>Services</h2><p>Support for local projects.</p></main>
<footer><p>Contact: workshop@example.com</p></footer>
</body>
</html>
The header introduces the page, nav groups primary links, main contains the dominant content and footer holds closing information. One h1 names the page and one main identifies its primary region.
