}

.rotating {
    -webkit-transform: rotate(360deg);
    -webkit-transition-duration: 1s;

Problem:

The code provided doesn't initiate the rotation animation as expected.

Solution:

To achieve continuous rotation using CSS, we need to employ an animation. In this case, we use the @keyframes rule to define the animation and the animation CSS property to apply it.

Updated Code:

<code class="css">@-webkit-keyframes rotating /* Safari and Chrome */ {
  from {
    -webkit-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  to {
    -webkit-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}
@keyframes rotating {
  from {
    -ms-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -webkit-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  to {
    -ms-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
    -webkit-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}
.rotating {
  -webkit-animation: rotating 2s linear infinite;
  -moz-animation: rotating 2s linear infinite;
  -ms-animation: rotating 2s linear infinite;
  -o-animation: rotating 2s linear infinite;
  animation: rotating 2s linear infinite;
}</code>

This updated code defines the rotating animation, which consists of a 360-degree rotation over a duration of 2 seconds. The infinite iteration count setting ensures that the animation repeats indefinitely.
