Alerts follow the same naming convention as all other components. The four main types of alerts you will use have the following class names

• .alert-success

  Use this to indicate that the application has completed something in the background or successfully saved a work item.

• .alert-info

  It's rare to need to alert the user of some information using the alert notification system. But if the need arises this is the class

• .alert-warning

  Use this to indicate potential problems with something the user is doing

  Do not use these alerts to validate input/forms. For that we use inline error messages!
• .alert-danger

  Use this to alert the user to some error or problem in the application. Again do not use this as part of any form validation!
