Heading

A heading is a section title that labels what follows and shows how a page is organized. In HTML they're ranked from H1 down to H6, nesting like an outline: for example, a page will often have one main H1, with H2s for major sections, and H3s for sub-sections, and so on.

Headings are more than bigger, bolder text. They carry structure that a screen reader uses to navigate and that a search engine reads to understand your page. Skipping levels for visual effect breaks that meaning, so keep the order honest and let styling handle the looks.
