Hey Ammar,

You want to set the transition-property as well as the transition-duration, but you only need to do this on the main class and not the pseudo-class.

.button {  
  background: #4682B4;
  transition-property: background; 
  transition-duration: .4s;
}

.button:hover {
    background: #356690;
}

You're doing this in the main class because the transition-duration is the same for both hover and exit, and therefore doesn't need to be declared (duplicate code) twice. While your code will work in the real world, the challenge wants to see that you know it can be done this way (which is better because it is DRY).

Hope that helped. Keep Coding! :)
