我有一个我正在开发的网站，我应该先完善布局。但是我现在面临着列没有一直到底的问题。我已经阅读了关于如何从另一个人那里获得 CSS 中的 3 列布局的教程 http://www.ejeliot.com/blog/61
问题是我还是迷路了。任何人都可以看看这个简单的模板 (www.centuryautosd.com/help.asp) 并制作 CSS，以便无论此页面有多高，列都向下延伸吗？数据是动态生成的，因此高度要求会随着浏览的每个页面不断变化。 这是真实页面的链接:www.centuryautosd.com/help.asp
谢谢!

这使用了 http://www.ejeliot.com/samples/equal-height-columns/example-4.html 中描述的技术您链接的页面的每个列都有一个负的底部边距，然后是一个 overflow hidden 的容器以隐藏粗糙的边缘。我没有将该技术应用于中间列，因为看起来该列总是最长的，但是如果您最终遇到中间列不是最长的情况并导致布局问题，您可以通过包括应用相同的技术
margin-bottom: -2000px;
padding-bottom: 2000px;
符合它的风格。
总而言之，我所做的是添加一个包含布局中三列的容器 div。然后，我为容器添加了一个隐藏的溢出，并将上面显示的边距和填充添加到列中。
