Don't include periods in short phrases or single sentences

Do not include periods in alert banner messages that are short phrases or single sentences. This helps keep the text quicker to read and easier to parse.

If the message must be more than one sentence in order to convey the alert's information, use a period at the end of each sentence.

Keep text concise and clear

Keep an alert banner's message concise while still being clear, using either a short phrase or a complete sentence that describes what's happening and what someone needs to know.

Whenever possible, include an in-line action for a user to take so that they can readily address the issue explained in the message.
