我使用http://www.dynamicdrive.com/style/layouts/item/css-liquid-layout-32-fluid-fluid-fixed/ 作为起点。我希望其中一列始终在顶部保持可见。我把{位置：固定；top: 0} 在右列 css 中，但这并没有达到我想要的效果。它只是使正确的列内容消失了。

如何实现我想要的（仅使用 css，最好不要使用 javascript，至少不要使用 jquery）。

以下是总代码。仅对原始行进行了 2 行修改。

您的 CSS 将第三列放在屏幕左侧，这就是它不可见的原因。更改您的 CSS 从

#rightcolumn {
   top: 0;
   position: fixed;
   float: left;
   width: 200px;
   margin-left: -200px; 
   background: #FDE95E;
}

到

#rightcolumn {
   top: 0;
   position: fixed;
   width: 200px;
   right: 0;
   background: #FDE95E;
}
