Heading structure per WCAG
Screen-reader users jump through the page via the heading list. That is why h1–h6 must reflect the content structure, not the appearance.
Rules
Exactly one h1 per page (the main topic). Do not skip levels (h2 → h4). Do not misuse headings for visual size — that is what CSS is for.
Common mistakes
Several h1s, an h3 as the first heading, a visually large text that is not a heading at all, or a real heading marked up as <p>.
