Capital letters are typically used at the start of a sentence and for proper nouns.
Headings
Headings always use sentence-case (not title-case), excluding H1 page headings which are all-caps.
Note: No full stops on the end of any headings - see Headings and subheadings.

Always use sentence-case for:
Navigation menus (unless linking a branded product).
CTA buttons and hyperlinks (no full stops but fine to use question marks)
Validation or error messages
Form fields
Numerical amounts
Capitalisation

Branded names (but not generic names of products or services)
Page meta titles (for SEO)
Guides
Holidays - see People & Diversity for more.
Days and months
Geographical names
Languages

Job titles (official titles only)

Lower-case
Always use lower-case for:

Online terms
Capitalisation rules do not apply when a formal name is written in lower or upper case.
States and territories
States and territories have each word capitalised.
Countries
Take note of the way we refer to certain countries.
- China – use China, not PRC
- United Kingdom - use UK or United Kingdom, not England or Great Britain
- United States - use US or United States, not USA, America or United States of America.
Note: For H1 headings, US reads as ‘us’, so use U.S.
