CSS Unused CSS Stages Transitions and Transforms Transitions - WebKit Only

stage 11 challenge 1

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.

<!DOCTYPE html>
    <title>CSS Transitions</title>
    <link rel="stylesheet" href="page.css">
    <link rel="stylesheet" href="style.css">
    <div class="box"></div>
/* Complete the challenge by writing CSS below */

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

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

You're being asked to use the Webkit prefix for your transition, so you'll need to start all of your transition properties with -webkit- in order to pass. Remember to also specify which properties you would like to transition. The challenge asks you to target the border-radius property, so your final .box code would end up looking something like this:

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

or the more compact shorthand:

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

Hope this helps!
