- Buttons should be sentence case. Only capitalize trademarks, brand names, or abbreviations that require it.
- Make the copy actionable (verb-like). For example, Continue might be preferable to Next. Better yet is something that suggests the specific action a user is taking. Avoid lazy terms like Submit.
- Avoid punctuation whenever possible. That means ampersands, commas, as well as ellipses.
- Articles (a, the) should be used sparingly on buttons. Keep the action to the point.
