QUESTION
I'm trying to clean up notifications for a client site and was wondering if the notification pattern that Stack Exchange employs has a name that I can use to search for more examples.
ANSWER
The terms I see the most are "message bar", "notify bar" and "notification bar".
There are tons of examples with Google using the terms above. Below are a few.
