    top: 0px;
    width: 100%;
    height: 100%;
    z-index: 1000;
}
.circle {
  width: 80px;
  height: 80px;
  border-radius: 40px;
  box-sizing: border-box;
  border: solid 10px rgba(255, 255, 255, 0.2);
  border-top-color: #FFF;
  animation: spin 1s infinite linear;
}

  }
  50% {
    transform: translate(0, 65px);

Hello, to center one element vertically and horizontally inside another, you should put these styles:

.circle{
  left:50%;
  top:50%;
  position: relative;
  margin-left:-40px; /* -1/2 width */
  margin-top:-40px; /* -1/2 height */
}

This solution is compatible with all browsers, both old and modern. The left margin should be - (half the width of the element), and the margin at the top should be - (half the element height).

I put your code in this fiddle for example, with the correction
