HTML Headings

<h1>Heading 1 — Page title</h1>
<h2>Heading 2 — Section title</h2>
<h3>Heading 3 — Subsection</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6 — Smallest heading</h6>SEO & Accessibility Rules
- Use only one h1 per page — it is your page title.
- Do not skip levels (e.g. don't go h1 → h3).
- Use headings for structure, not for visual size (use CSS for size).
Search engines use your h1 to understand what the page is about. Make it descriptive.
