我正在通过 CSS 背景使用字体真棒旋转图标来加载页面。

    /* Styles go here */
.loading-icon {
  position: relative;
  width: 20px;
  height: 20px; 
  margin:50px auto;
}

.loading-icon:before {
  content: "\f110";
  font-family: FontAwesome;
  font-size:20px;
  position: absolute;
  top: 0; 
}
<!DOCTYPE html>
<html>

<head>
  <link data-require="fontawesome@*" data-semver="4.5.0" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.css" />
  <link rel="stylesheet" href="style.css" />
</head>

<body>
  <div class="loading-icon"></div>
</body>

</html>

该图标在页面中成功呈现，但它是静态的。我如何使用以令人敬畏的字体为背景的动画旋转图标？请协助。

你应该使用fa fa-spinner fa-spin.

请参阅：字体真棒示例

例子： 

/** CSS **/
@import url('https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.css');
<!-- HTML -->
<div class="fa fa-spinner fa-spin"></div>

正确答案：更新 CSS，如下所示。

    /* Styles go here */
.loading-icon {
  position: relative;
  width: 20px;
  height: 20px; 
  margin:50px auto;
  -webkit-animation: fa-spin 2s infinite linear;
  animation: fa-spin 2s infinite linear;
}

.loading-icon:before {
  content: "\f110";
  font-family: FontAwesome;
  font-size:20px;
  position: absolute;
  top: 0; 
}
<!DOCTYPE html>
<html>

<head>
  <link data-require="fontawesome@*" data-semver="4.5.0" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.css" />
  <link rel="stylesheet" href="style.css" />
</head>

<body>
  <div class="loading-icon"></div>
</body>
