Notifications are one of the most used parts of each website. You may need them when a user signs up, selects something, or etc. Adding effects to them makes them more perfect. The following code provides three different alert boxes to preview success messages, warnings and information. They have close buttons. When they are clicked, the related boxes fade out. See the demo!
