我最近接管了一些来自我之前构建它们的人的hubspot页面。在这个特定的页面上，我有两列 - 一个在左边，一个在右边（有一个灰色的背景）。当前左栏的内容比右栏的内容多，因此右栏的灰色背景不会一直延伸到页面的下方，而是停在其内容的底部。没什么大不了的？我只会使用clearfix ..但是clearfix没有任何作用。好吧，我只会使用JavaScript ...但在尝试使用不同的脚本后，它也无法正常工作。我已经尝试了多个版本的clearfix hack。为什么clearfix无法在此列上工作？
有人可以帮我从右栏中获得这个dang灰色背景，一直延伸到页面的底部（与左栏相同的高度）吗？我会在你的债务！
这里的页面：http://info.brushresearch.com/end-brushes
下面是我用的是最新的CSS代码：
.z-clearfix:after {
visibility: hidden;
display: block;
font-size: 0;
content: " ";
clear: both;
height: 0;
}
.z-clearfix { display: inline-block; }
/* start commented backslash hack \*/
* html .z-clearfix { height: 1%; }
.z-clearfix { display: block; }
/* close commented backslash hack */
下面是我使用的基本HTML ...
<div class="z-clearfix">

<p>Industrial and automotive applications include cleaning parts, polishing dies, and removing carbon deposits from piston heads, cylinders, and valve seats.</p>
<h4>Types of End Brushes</h4>

</ul>
<p>Most end brushes have carbon steel or stainless steel filaments. Nylon, abrasive nylon, and brass filaments are available for some solid end brushes.</p>
<p>End brushes also differ in terms of end-style. Brushes with standard ends are great for general-purpose use. Banded tools have less trim and produce less flare. End brushes with coated cups protect the workpiece from contact with the metal body. </p>
