CSS边栏高度100%

css

数小时以来,我一直在脑海中摸索,试图找出这个问题,并认为这一定是我所缺少的。我已经在网上搜索过,但没有发现有效的方法。HTML是:

<body>
  <div id="header">
    <div id="bannerleft">
    </div>

    <div id="bannerright">
      <div id="WebLinks">
        <span>Web Links:</span>
        <ul>
          <li><a href="#"><img src="../../Content/images/MySpace_32x32.png" alt="MySpace"/></a></li>
          <li><a href="#"><img src="../../Content/images/FaceBook_32x32.png" alt="Facebook"/></a></li>
          <li><a href="#"><img src="../../Content/images/Youtube_32x32.png" alt="YouTube"/></a></li>
        </ul>
      </div>
    </div>
  </div>
  <div id="Sidebar">
    <div id="SidebarBottom">
    </div>
  </div>
  <div id="NavigationContainer">
    <ul id="Navigation">
      <li><a href="#">Nav</a></li>
      <li><a href="#">Nav</a></li>
      <li><a href="#">Nav</a></li>
      <li><a href="#">Nav</a></li>
      <li><a href="#">Nav</a></li>
      <li><a href="#">Nav</a></li>
    </ul>
  </div>
  <div id="Main">
    <!-- content -->
  </div>
</body>

我的完整CSS是:

* {
  margin: 0px;
  padding: 0px;
}

body {
  font-family: Calibri, Sans-Serif;
  height: 100%;
}

#header {
  width: 100%;
  z-index: 1;
  height: 340px;
  background-image: url("../../Content/images/bannercenter.gif");
  background-repeat: repeat-x;
}

#header #bannerleft {
  float: left;
  background-image: url("../../Content/images/bannerleft.gif");
  background-repeat: no-repeat;
  height: 340px;
  width: 439px;
  z-index: 2;
}

#bannerright {
  float: right;
  background-image: url("../../Content/images/bannerright.gif");
  background-repeat: no-repeat;
  width: 382px;
  height: 340px;
  background-color: White;
  z-index: 2;
}

#Sidebar {
  width: 180px;
  background: url("../../Content/images/Sidebar.png") repeat-y;
  z-index: 2;
  height: 100%;
  position: absolute;
}

#SidebarBottom {
  margin-left: 33px;
  height: 100%;
  background: url("../../Content/images/SidebarImage.png") no-repeat bottom;
}

#NavigationContainer {
  position: absolute;
  top: 350px;
  width: 100%;
  background-color: #bbc4c3;
  height: 29px;
  z-index: 1;
  left: 0px;
}

#Navigation {
  margin-left: 190px;
  font-family: Calibri, Sans-Serif;
}

#Navigation li {
  float: left;
  list-style: none;
  padding-right: 3%;
  padding-top: 6px;
  font-size: 100%;
}

#Navigation a:link, a:active, a:visited {
  color: #012235;
  text-decoration: none;
  font-weight: 500;
}

#Navigation a:hover {
  color: White;
}

#WebLinks {
  float: right;
  color: #00324b;
  margin-top: 50px;
  width: 375px;
}

#WebLinks span {
  float: left;
  margin-right: 7px;
  margin-left: 21px;
  font-size: 10pt;
  margin-top: 8px;
  font-family: Helvetica;
}

#WebLinks ul li {
  float: left;
  padding-right: 7px;
  list-style: none;
}

#WebLinks ul li a {
  text-decoration: none;
  font-size: 8pt;
  color: #00324b;
  font-weight: normal;
}

#WebLinks ul li a img {
  border-style: none;
}

#WebLinks ul li a:hover {
  color: #bcc5c4;
}

我希望侧边栏可以随着页面内容的高度而扩展,而将侧边栏底部的图像始终保留在侧边栏的底部。
