Donut spinner

Creates a donut spinner that can be used to indicate the loading of content.

HTML

<div class="donut"></div>

CSS

@keyframes donut-spin {
  0% { transform: rotate(0deg); }
  100% { transform: rotate(360deg); }
}
.donut {
  display: inline-block;
  border: 4px solid rgba(0, 0, 0, 0.1);
  border-left-color: #7983ff;
  border-radius: 50%;
  width: 30px;
  height: 30px;
  animation: donut-spin 1.2s linear infinite;
}

Explanation

Use a semi-transparent border for the whole element, except one side that will serve as the loading indicator for the donut. Use animation to rotate the element.
