我最近从我之前构建它们的人那里接过了一些hubspot页面。在这个特定的页面上，我有两列 - 一列在左边，一列在右边（有灰色背景）。左列目前的内容比右侧更多，因此右列的灰色背景不会一直向下延伸到页面，而是停在其自己内容的底部。没什么大不了的？我只会使用clearfix ..但是clearfix什么都不做。好的，我只会使用JavaScript ...但在尝试不同的脚本后，它也无法正常工作。我试过了clearfix hack的多个版本。
有人可以帮我从右栏中获得这个灰色背景，一直延伸到页面底部（与左栏相同的高度）？我会欠你的债！
以下是页面：http://info.brushresearch.com/end-brushes
这是我使用的最新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 */
这是我正在使用的基本HTML ...

<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>

您可以在父元素中添加类：
<div class="row-fluid " style="position: relative;">
你可以为你的侧边栏做到这一点：
element.style {
background: #ececec;
padding: 20px 80px;
position: absolute;
right: 0;
height: 100%;
/* padding-bottom: 30em; */
}
我尝试了它的作品。
希望有所帮助

感谢您的帮助。所以，为了澄清，我将.row-fluid类添加到具体的元素中？
然后我将提供的CSS代码应用于.sidebar.right？
