我试图实现这个CSS动画，但不知道该怎么做。我想围绕圆圈旋转顶部边框，但整个过程包括文本旋转。我只想在360度旋转顶部边框。以下是我的代码段：

＆＃13;
＆＃13; 
div#skill {
    /*background: url(../img/white.jpg) center no-repeat;
    background-size: cover;*/
    background-color: rgba(144, 0, 64,0.8);
    color: #fff;
    padding: 10px 0;
}

div#skill h3 {
    color: #fff;
    text-transform: none;
}

div#skill .row {
    margin-right: -15px;
    margin-left: -15px;
    padding: 15px 150px;
}

div#skill .circle {
    height: 120px;
    width: 120px;
    border: 5px solid #ccc;
    border-top-color: orange;
    border-radius: 60px;
    background-color: #74002f;
    /*Making the top border to spin*/
    animation: spin 2s linear infinite;
}

div#skill .circle:after {
    content: url(../img/icons/arrow-point-to-right.png);
    position: absolute;
    top: 25px;
    right: 0;
}

div#skill .circle.last:after{
    display: none;
}

.circle .caption {
    font-weight: bold;
    padding: 20px 24px;
}

.caption h6 {
    font-size: 15px;
}


/*Animation on circle*/
@keyframes spin {
    from {transform: rotate(0deg);}
    to {transform: rotate(360deg);}
}

解决方案是制作另一个div，它将位于.circle position:absolute;之后，它将如何“占用”.circle大小但不包含.circle内容。

div#skill {
  /*background: url(../img/white.jpg) center no-repeat;
  background-size: cover;*/
  background-color: rgba(144, 0, 64,0.8);
  color: #fff;
  padding: 10px 0;
}

div#skill h3 {
  color: #fff;
  text-transform: none;
}

div#skill .row {
  margin-right: -15px;
  margin-left: -15px;
  padding: 15px 150px;
}

div#skill .circle {
  position:relative;
  height: 120px;
  width: 120px;
  border: 5px solid #ccc;
  /*border-top-color: orange;*/
  border-radius: 50%;
  background-color: #74002f;
}

div#skill .circle:after {
  content: url(../img/icons/arrow-point-to-right.png);
  position: absolute;
  top: 25px;
  right: 0;
}

div#skill .circle.last:after{
  display: none;
}

.circle .caption {
  font-weight: bold;
  padding: 20px 24px;
  position:relative;
  z-index:1; 
}

.caption h6 {
  font-size: 15px;
}

.circle-rotate {
  height: 100%;
  width: 100%;
  border-top: 5px solid orange;
  border-radius: 60px;
  background-color: #74002f;
  /*Making the top border to spin*/
  animation: spin 2s linear infinite;
  position:absolute;
  top:0;
  left:0;
}
