我只需要在内容中显示预加载器＆＃39; div，但preloader隐藏了整个页面。结构网站：

1. 标题
2. 菜单
3. 内容（此处我需要预加载器）
4. 页脚

我无法找到，我需要插入预加载器的代码......

使用FontAwesome微调器的简单解决方案。使用的颜色仅用于可视化。

$(".spinner").delay(1400).fadeOut();

header,
nav,
footer {
  width: 100%;
  height: 50px;
}

header {
  background-color: red;
}

nav {
  background-color: blue;
}

footer {
  background-color: green;
}

.content {
  width: 100%;
  height: 200px;
  position: relative;
}

.spinner {
  width: 100%;
  height: 100%;
  background-color: purple;
  text-align: center;
  display: table;
}

.spinner i {
  display: table-cell;
  vertical-align: middle;
  color: white;
}
