Why I am wrong?

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.

.box { border-radius: 15px; background: #4682B4; }

.box:hover { background: #F08080; border-radius: 50%; -webkit-transition-property:border-radius; -webkit-transition-duration:2s; -webkit-transition-timing-function:linear; -webkit-transition-delay:1s; }

Transition properties go on the element itself not it's hover state.

Something tells me that you can't transition from an initial pixel value to a percentage value... try changing the border-radius value in the hover state to a px value?
