 confirmation by clicking and disappears quickly. It is centered and has a
 neutral gray color.

+Warnings are messages of medium importance. They are displayed with colors that
 are neither neutral nor too distractive. A warning is displayed for 1.5 seconds,
 but the user can click the message box to dismiss it. The user can continue to
 interact with the application while the warning is displayed.

+Error messages are notifications that require the highest user attention, with
 alert colors, and they require the user to click the message to dismiss it. The
 error message box does not itself include an instruction to click the message,
 although the close box in the upper right corner indicates it visually. Unlike
 with other notifications, the user can not interact with the application while
 the error message is displayed.

++
+Tray notifications are displayed in the "system tray" area, that is, in the
 lower-right corner of the browser view. As they do not usually obscure any user
 interface, they are displayed longer than humanized or warning messages, 3
 seconds by default. The user can continue to interact with the application
 normally while the tray notification is displayed.
