我的网站：http ://web.njit.edu/~dp257/boilerplate/website.html#

我希望我的侧栏下降到页脚的顶部或与我的内容相同的长度。我所以我不想使用 JQuery 或类似的东西。我确定它必须在 CSS 中应该是一个简单的修复，但我正在消隐。

   <div id = "wrapper">
   <header id="name" align="center">MY IS117 Website</header>
   <div id="primary_links" align="center">
      <ul>
         <li><a href="#">Menu 1</a></li>

你想让你的侧边栏在右边吗？与您的内容高度相同？如果这是正确的，您可以float: right;在您的#sidebar. 将您的内容和侧边栏放在一个新的 div 中，给他一个类，例如：.wrapper。并在.wrapper. 如果高度改变，背景会改变，背景也会重复。

.wrapper {
width: 100%;
background: url('yourimage') repeat;
/* float: left; */
overflow: hidden;
}

我希望你明白这一点。如果你愿意，我也可以给你举个例子。

编辑：您可以使用float left, 给父 div 孩子的高度。或者你可以使用overflow: hidden;.

利用：

  1. 对于#sidebar：clear: right;
  2. 对于#footer：clear: both;

在您的页脚到底部和侧边栏到右侧之后。

添加div环绕#content和#sidebar。我打电话给 div #content-sidebar-wrap。添加display:table到#content-sidebar-wrap和添加display:table-cell到#content和#sidebar。

#content-sidebar-wrap{
display:table;
height:100%;
}

#content {
width: 508px;
padding-left: 23px;
padding-right: 23px;
border: 1px solid;
float: left;
display:table-cell;
}

#sidebar {
width: 338px;
float: left;
border: 1px solid;
height:100%;
display:table-cell;
}

一个简单的方法让这个正常工作，只是添加一些巨大padding-bottom的.sidebar，然后用相同的（但负面的）来对抗它margin-bottom。只需确保将 设置overflow:hidden为包装类。我建议您同时移动header外包装footer。

现在试试这个

#wrapper {
background: none repeat scroll 0 0 #B3D4FC;
margin-left: auto;
margin-right: auto;
width: 898px;
}
#primary_links {
background: none repeat scroll 0 0 #FFFFFF;
border: 1px solid;
height: 75px;
line-height: 75px;
}

#name {
background: none repeat scroll 0 0 #FFFFFF;
border: 1px solid;
margin-left: auto;
margin-right: auto;
padding-left: 31px;
padding-right: 31px;
}

#sidebar {
background-color: #ADD8E6;
border: 1px solid;
float: right;
width: 290px;
}
