Question

当我向下滚动浏览器时，我正试图让div保持在右上角。在桌面上查看它看起来不错。但是当在平板电脑上观看时，这是一团糟。是否有一种更优雅的方式来定位div，使用户在所有屏幕中向下滚动时看到。我正在使用Bootstrap。这是DEMO 这是HTML引导代码：

Answer 1

<div class="container">

  <div class="row">
    <div style="position:fixed;top:20px;float:left;left:0px;"class="col-sm-8">

Answer 2

据我所知，没有CSS解决方案可以为旧移动浏览器实现position: fixed容器。您可以编写一个javascript来调整容器在每个滚动事件上的位置，但这在iOS上不能很好地工作，因为iOS仅在滚动完成后才会触发onscroll事件，而不是在滚动时触发。这意味着容器在滚动后跳转到固定位置而不是停留在那里。

然而，有一些高级JS库使用虚假滚动容器模拟滚动行为，并绕过所描述的问题，例如： http://cubiq.org/iscroll-5
