Casing conventions and guidelines to make the content consistent and readable.

Sentence case

Sentence case is the most used case and is easiest to scan. When writing in sentence case, only capitalize the first letter of the sentence.

  • All headings
  • All text
  • Buttons, links, and calls-to-action

Title case

Only use title case for titles of published works, proper nouns, and, if necessary, job titles. When writing in title case, capitalize most words except:

  • Articles (a, an, the)
  • Coordinating conjunctions (and, but, for)
  • Short words (fewer than four letters and not a “major” word: nouns, verbs, adjectives, adverbs, and pronouns)
  • Prepositions (at, by, from)

All caps

Never write in all caps. All caps text is difficult and stressful to read. Screen readers also struggle to recognize all caps text. Screen readers will identify each individual letter instead of the word the letters are spelling.

All caps text is only acceptable in pretitles and product names. When writing in all caps, do not use the caps lock setting. The components will set the text so that it presents as all caps while remaining discernible to screen readers.
