transitions and transforms

Using the prefix for WebKit-based browsers, create a transition for the border-radius property of .box. Give the transition a duration of 2 seconds, a delay of 1 second, and a timing function that maintains a linear motion.

  transition-delay: 1s;
  transition-timing-function: linear;

Hi Angeline,

You have to add "webkit" and border-radius missing on the function property

.box {
    border-radius: 15px;
    background: #4682B4;
    -webkit-transition: border-radius;
    -webkit-transition-duration: 2s;
    -webkit-transition-delay: 1s;
    -webkit-transition-timing-function: linear; 
 }

.box:hover {
    background: #F08080;
    border-radius: 50%;
}
