In sentences (without spaces): “And the government worked fast—internet time—to launch it and to keep it responsive to the American people and the world.”
For all other cases, such as phone numbers (1-202-720-2791).
Use serial commas before a conjunction in a series of items. A serial comma is a comma that comes before the final conjunction (and, but, or) in a list.
Spanish: No serial commas are necessary unless there is a conjunction in a clause immediately before the last conjunction of the sentence; for example, ese vestido es bonito, azul y blanco como querías, y te queda muy bien.
Periods and More
In bulleted and numbered lists, do not use a period or other punctuation after titles or phrases that are not complete sentences (also good for accessibility).
Exclamation points and question marks need to be opened and closed: ¿ ? ¡ !
Punctuation marks are written outside of quotation marks, parentheses, and dashes.
Plural form of organization names or countries are made by using double letters, a period and a space after the first double letters: ferrocarriles (FF. CC.), Estados Unidos (EE. UU.).
If you need to look up some grammar rules, see these helpful resources in English and Spanish:
Use “and” rather than “&” unless there is a compelling reason; for example, an agency’s official name such as Centers for Medicare & Medicaid Services.
If an agency’s acronym is commonly used, place it in parentheses following the agency’s full name on first use, and use the acronym in subsequent instances. FBI, IRS, or FEMA are examples of agency acronyms that are more familiar to people than the full agency name.
Spell out the full name of an agency and programs in listings of federal, state, or local government agencies: General Services Administration, not GSA.
Write acronyms in all caps and without periods between the letters: USDA, not U.S.D.A.
Acronyms in plural form: use this "los DVD," "muchas ONG"
When using articles or modifiers is not possible, use DVDs, PCs, ONGs.
If an English acronym is used, include the acronym, a comma and sigla en inglés (GSA, sigla en inglés).
When including hyperlinks in text, be sure the hyperlinked text is descriptive of its destination and/or purpose. Use unique link titles for each link destination. Provide only as many links that are necessary for users to complete tasks rather than providing too many link options. See additional instructions for Spanish.
Do this: Check with banks or credit unions to compare their current published rates.
Avoid hyperlinking to alternate file formats when possible. If you must link to a PDF, the CMS will automatically add the needed PDF information after the link. The PDF information (PDF, Download Adobe Reader) will only be visible in the published version of the asset.
When indicating that text is a web address in printed content, apply one style enhancement, such as colored, bolded, or underlined text. There isn't one preferred style to use, but no matter which style you choose, apply it consistently.
Full web addresses should be included in printed text, rather than shortened URLs.
While shortened URLs work fine when posted as a link on a website, email, or in the electronic version of a PDF, these character strings may not work for print publication readers who type the shortened URL directly into a browser.
English: Use italics sparingly, because they’re hard to read on a screen.
Spanish: Use quotes or italics only when referring to other language text within a Spanish narrative.
Write email addresses in lowercase and as active links.
American Indians, Alaska Natives, Native Hawaiians, and American Samoans are all Native Americans.
Some government programs and benefits are specifically for American Indians and not for all Native Americans. Follow the wording the agency administering the program uses to describe which programs serve which groups.
Use Mes de la Herencia Nativa Americana when referring to National Native American Heritage Month.
Use Mes del Indio Americano when referring to National American Indian Heritage Month.
