Background color only

Any style of alert box can be made to be background-color only. Use background-color only alerts only for immediate feedback, such as in single-page applications or Ajax forms. They shouldn’t be used for static alert messaging.

See this in Storybook

  • Some users might not be able to distinguish differences in the background color or see the color at all. Don’t rely on color alone to convey context.
  • Messaging should be direct and concise. Aim for one or two lines.
  • Don’t use headings for background-color only alerts.

Full-width alerts

Full-width alerts are used only for emergency or urgent communications and should appear below the main navigation.

More about full-width alerts

  • Only available in info or warning variants.
  • Content inside alert remains aligned to the main page grid container. This might not be apparent on this site in smaller screens.
  • Use for emergency or very urgent communications only. For example, a hurricane alert; government shutdown affecting VA services, etc. Emergency homepage alerts notify Veterans, VA employees, and the public of events that affect VA services or site features.
  • To ensure that customers always know they can find critical service information in this area, don’t use emergency homepage alerts for general press, outreach, or administrative messages.
  • Don’t stack - max is one full-width alert per page at any one time. (If multiple emergency issues occur at once, combine the message and link out to a landing page or to individual affected medical centers, for example.)
  • Can be used on homepage or, in true emergencies, on lower-level pages.

Usability

When to use alerts

Use Alert boxes to notify users of the status of the site, which may or may not require a user’s response. This includes errors, warnings, and general site updates. Use Alert boxes to alert users that something they need needs to be correct or to confirm successful completion of a task.

When to consider something else

  • On long forms, always include in-line validation in addition to any error messages that appear at the top of the form.
  • If an action will result in destroying a user’s work (for example, deleting an application) use a more intrusive pattern, such as a confirmation modal dialogue, to allow the user to confirm that this is what they want.

How to use alerts

When the user is required to do something in response to an alert, let them know what they need to do and make that task as easy as possible. Think about how much context to provide with your message. A notification of a system change may require more contextual information than a validation message. The message should be concise, in plain language, and adhere to VA.gov voice and tone principles. Don’t use jargon and computer code in the message.

  • Be polite in error messages — don’t place blame on the user.
  • Users generally won’t read documentation, but they’ll read a message that helps them resolve an error; include some educational material in your error message.
  • But don’t overdo it — too many notifications will either overwhelm or annoy the user and are likely to be ignored.
  • Allow a user to dismiss a notification wherever appropriate.
  • Don’t include notifications that aren’t related to the user’s current goal.
  • Don’t stack alerts one after the other.
  • If the alert appears within the page body content, it should be co-located with relevant content.

Accessibility considerations

Use the ARIA role="alert" to inform assistive technologies of a time-sensitive and important message that isn’t interactive. If the message is interactive, use the alertdialog role instead. Don’t visually hide alert messages on the page and then make them visible when they are needed. Users of older assistive technologies may still be able to perceive the alert messages even if they are not currently applicable.
