Don’t use end punctuation in headlines, headings, subheadings, UI titles, or UI text. If the end of a sentence is a link, do not include the period in the link.
End all sentences with a period, even if they’re only two words. Put one space, not two, after a period.
Be brief—make every word count
Be brief. Make every word count.
In bulleted and numbered lists, end each list item with a period if:
- Any item forms a complete sentence when combined with the list introduction that precedes the colon.
- Exception: Don’t use periods if all the items are UI labels, headings, subheadings, or strings.
- Any item by itself is a complete sentence.
- Don’t use semicolons, commas, or conjunctions (and, or, but) at the end of list items. List items will either end with a period or not.
