Now that you have Devise setup with signup and signin links, it's time to add some CSS to those pages.

Styling the Flash Message

What happens when someone tries to sign in with incorrect information? Devise displays an error in the code you added, but there's no CSS to mark it:

  background-color: #f45252;

  background-color: #bef0ff;
