Question

<div id="Dvloading" style="float: left;">
        <i id="loadingSpinner" class="icon-spinner icon-spin blue" style="margin-left: 50%; position:absolute ; margin-top: 25%; z-index: 1000; font-size: 800%;"></i>
</div>

这是在页面加载时显示加载图形的代码。它显示在网格视图上方。当网格由大量行组成时，当我向下滚动页面时，我无法看到加载图形。但是当我走到屏幕顶部时，我可以看到加载图形。即使滚动页面，我如何将它始终保持在屏幕中间？

请帮帮我。

Answer 1

试试这个：

.centered {
  position: fixed;
  top: 50%;
  left: 50%;
  margin-top: -50px; //Half of the height of the loading graphic
  margin-left: -50px; //Half of the width of the loading graphic
}
