(h1 and h2 level headings automatically display in all caps). Use title case for most headings, capitalizing the first and last words of the heading and all major words in between. This includes nouns, pronouns, verbs, adverbs, and adjectives.

Articles (a, an, the) and short prepositions (e.g., in, on, at) are typically not capitalized unless they are the first or last word of the heading.

Capitalize brand names and product names according to the brand’s or product’s preferred capitalization style. Example: “Introducing the New iPhone 13”

These categories may follow AP style formatting which entails only capitalizing the first letter of the heading unless proper nouns are included or other words that require capitalization.

The title of a page will always be labeled as an h1 element. There should only be one h1 element per page. Paragraph text that belongs to the page as a whole may immediately follow the h1 without a child element, but additional paragraphs of copy would be required to belong to an additional heading level beyond the h1.

Any headings that fall into the body content besides the title will be labeled as h2 headings. They are considered children elements to the parent (page). Consecutive heading sections that deal with different subject matter would both be labeled as h2.

An h3 element is used when a section is added that is a subset of the h2 section. H3 is considered a child of h2, so it’s subject matter is segmented but related to its parent section.

The website supports up to semantic levels of h6, following the same parent-child relationship. Not all paragraphs are required to have a heading, but ones that do should have their relationship considered to decide what heading level should be used.

Headings in some block styles will appear different. Semantic headings are built into blocks with the most predictable use in mind.
