When to Avoid Contractions
There are times to not use a contraction.
- Many contractions are a combination of a word and "not." We want to tell customers what they can do, not what they can’t. Remember to use a positive voice when you can. Do this: Please enter an amount. Not this: You can’t save an expense report unless you enter an amount.
- Don’t start a question with a negative contraction.
- Don’t use contractions that can have multiple meanings, such as "they’d" (they had or they would) or "you’d" (you had or you would).
Lists
When creating a numbered or bulleted list, follow these rules:
- Introduce a list with a clear, descriptive sentence or phrase.
- Use numbered lists only when the sequence or count of items is important.
- Write list items to have approximately similar line lengths.
- Use parallel sentence construction for list items. Meaning, make sure each list item starts with the same part of speech (e.g., noun, verb) and that they are all either fragments or complete sentences.
- Avoid repeating the same word(s) at the beginning of each list item.
- Keep formatting consistent.
- Stay with full sentences (capitalize + punctuation) or stay with phrases (no period)
- Capitalizing the first word will help scanning.
Periods
Periods are used for complete sentences. Not all complete sentences will have periods. Refer to the Usage section of UI Copy, Page Elements, & Components for specific usage.
Truncation
In general, try to avoid truncation. However, space restrictions and/or localization often require us to put text into spaces where it will not always fit.
Some common places where truncation may occur:
- A breadcrumb in the navigation area may exceed the space allowed
- Information in a table column may not fit, even with wrapping
- Options in a drop-down menu may be wider than the menu window
The general rule is to truncate the end of the word with an ellipsis (…) and show the full text on hover. When wrapping multiple lines of text, use a "Show more" link at the end to expand the text and a "Show less" link to collapse the text.
Breadcrumbs
Try to maintain at least the current page and the top-level page when shortening breadcrumbs. Priority is given to not truncate the items next to the current page to give the user the most relevant context.
For example:
Earth > North America > United States > Washington > Bellevue
Earth > … > United States > Washington > Bellevue
Earth > … > … > Washington > Bellevue
Earth > … > … > … > Bellevue
… > … > … > … > Bellevue
… > Bellevue
… > Bel…
Email Addresses
Try to not truncate email addresses. If you must, truncate from the domain end. Always show the full email address on hover.
For example:
reallylongname@company.com
reallylongname@comp…
really…
